Can someone help me with this problem please??? If ƒ( x ) = x 2 + 1 and g( x ) = 3 x + 1, find 2 · ƒ(4). A. 18 B.34 C.65
Answer: B
Step-by-step explanation:
They've given you two functions f(x) = x^2 + 1 and g(x) = 3x +1 And they are you to find 2 * f(4) then g(x) is not needed so input in 4 for the function f(x) and multiply the output by 2.
F(4) = 4^2 + 1
F(4) = 16 +1
f(4) = 17
17 * 2 = 34
Answer:
B.34Step-by-step explanation:
[tex]f( x ) = x^ 2 + 1 \\ g( x ) = 3 x + 1\\\\f(4) \times 2 = ?\\f(4) = 4^2 +1\\\\=( 16+1) \times 2\\\\= 17\times 2\\\\= 34[/tex]
Solve -4(x + 1) – 3 = -3(x - 4).
Answer:
x =-19
Step-by-step explanation:
[tex]-4(x + 1) - 3 = -3(x - 4).\\\\\mathrm{Expand\:}-4\left(x+1\right)-3:\quad -4x-7\\\\\mathrm{Expand\:}-3\left(x-4\right):\quad -3x+12\\-4x-7=-3x+12\\\\\mathrm{Add\:}7\mathrm{\:to\:both\:sides}\\-4x-7+7=-3x+12+7\\\\Simplify\\-4x=-3x+19\\\\\mathrm{Add\:}3x\mathrm{\:to\:both\:sides}\\-4x+3x=-3x+19+3x\\\\Simplify\\-x=19\\\\\mathrm{Divide\:both\:sides\:by\:}-1\\\frac{-x}{-1}=\frac{19}{-1}\\\\Simplify\\x=-19[/tex]
Answer:
We have this equation:
-4(x+1) - 3 = -3(x-4)
First of all, we solve the paretheses:
-4x - 4*1 - 3 = -3x - (-3*4)
-4x - 4 - 3 = -3x + 12
-4x -7 = -3x + 12
We sum 7 on both sides and 3x on both too:
-4x - 7 + 7 + 3x = -3x + 12 + 3x + 7
-4x + 3x = 12 + 7
-x = 19
x = -19
Now we can verify:
-4(-19+1) - 3 = -3(-19-4);
-4(-18) - 3 = -3(-23);
72 - 3 = 69 (TRUE)
How do I solve this?

The function h(x)=4/3x-1 represents the composite h(x)=f(g(x)).if f(x)=2x-1,what is g(x)
Answer:
[tex]g( x) = \frac{2}{3}x[/tex]
Step-by-step explanation:
Given:
Composite Function:
[tex]h( x)=f( g( x))[/tex]
Also,
[tex]h( x)=\frac{4}{3}x-1[/tex]
To find:
[tex]g( x ) = ?[/tex]
Solution:
First of all, let us learn about a composite function.
Composite function [tex]f( g( x))[/tex] means to write [tex]g( x)[/tex] in place of [tex]x[/tex] in the function [tex]f( x)[/tex].
Let [tex]g( x) = y[/tex]
So, [tex]f( g( x))[/tex] = [tex]f( y )[/tex].
Therefore,
[tex]h( x) =f( g( x)) = f( y)[/tex]
So, [tex]f( y) = 2y-1[/tex]
We have to solve for [tex]y[/tex] in terms of [tex]x[/tex] to find the value of [tex]g(x)[/tex]:
[tex]\Rightarrow \frac{4}{3}x-1 = 2y-1\\\Rightarrow 2y=\frac{4}{3}x\\\Rightarrow y = \frac{2}{3}x[/tex]
Hence, the answer is [tex]g( x ) = \frac{2}{3}x[/tex].
Checking whether the answer is correct or not:
[tex]f( g( x)) = f( \frac{2}{3}x) = 2\times \frac{2}{3}x -1 = \frac{4}{3}x-1[/tex]
which is [tex]h( x)[/tex].
Hence, our answer [tex]g( x ) = \frac{2}{3}x[/tex] is correct.
The g(x) of the function is:
g(x) = (2/3)x
How to find what g(x) is?A function is a relationship between inputs where each input is related to exactly one output.
Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
We have:
h(x) = (4/3)x - 1
h(x) = f(g(x))
f(x) = 2x - 1.
Thus, we can say:
h(x) = f(g(x)) = 2*g(x) - 1
(4/3)x - 1 = 2g(x) - 1
(4/3)x - 1 + 1= 2g(x)
(4/3)x = 2g(x)
(4/3)x * 1/2 = g(x)
(2/3)x = g(x)
g(x) = (2/3)x
Therefore, g(x) = (2/3)x.

Answer:
Y=40
X=67
Step-by-step explanation:
In a cross line problem, one part of the cross, (such as 63°) is always the same on the other side. (like y+23° and 63°. This means Y=40 because 40+23 is 63.
To find x, you must know that 360° is all the way around in degrees. you know that 126° (63 +63) is already taken up. So you subtract 126 from 360 and then multiply the answer by 1/2 because you trying to find the bottom total.(360-126)=234(1/2)= 117 Lastly, you find X in the equation 2x-17=117.

Step-by-step explanation:
A contains √3 --> irrational number because 3 is not a square number
For other choices:
- All numbers in the form a/b (a,b are integer numbers) are rational numbers
- √36, √9, √4, √25, √49, √100 are integer numbers because (36, 9, 4,....) are square numbers
- All given decimal numbers can be written in the fraction form
0.5 = 1/2
39.77 = 39 + 77/100 = 3977/100
0.15151578 and 0.00010001 are finite decimals, 0.303030... is infinite repeating decimal, so technically they are rational numbers.
A rectangular pool is twice as
long as it is wide. What are the
dimensions of the pool if the
perimeter is 48 yd?
Step-by-step explanation:
L=2B
P=2(L+B)
48=2(2B+B)
48=2(3B)
48=6B
B=8yd
L=2*8
=16yd
Answer:
length * width = 16 yd * 8 yd
or
length = 16 yd
width = 8 yd
Step-by-step explanation:
take the rectangular pool to have sides a (length) and 2a (width).
we are told that the length is as twice as its width, therefore,
Perimeter is given by (a + 2a) × 2 = 48 yd
Divide both sides by 2 ⇒ [tex]\frac{((a + 2a) * 2)}{2} = \frac{48 yd}{2}[/tex] ⇒ a + 2a = 24 yd
⇒3a = 24 yd
Divide both sides by 3 ⇒ [tex]\frac{3a}{3} = \frac{24 yd}{3}[/tex] ⇒ a = 8 yd
therefore, the width of the pool is 8 yd and its length is 16 yd (Twice as long as it is wide)
Which of the following options correctly represents the complete factored form of the polynomial?
Answer:
B
Step-by-step explanation:
f(x)=(x-3)(x²+2x+2)
when solve for x using quadratic formula fo x in (x²+2x+2):
x=(-b±√b²-4ac)/2a a=1,b=2,c=2
x=-1±i
f(x)=(x-3)(x+1-i)(x+1+i)
The complete factored form of the polynomial is F(x) = (x - 3)(x + 1 + i)(x + 1 - i).
To find the complete factored form of the polynomial F(x) = x³ - x² - 4x - 6, we can factor it using various methods such as synthetic division or factoring by grouping.
Factoring the polynomial, we get:
F(x) = (x + 3)(x - 1)(x + 2)
Comparing the factored form with the options provided:
A. F(x) = (x + 3)(x + 1)(x - 1)
This option does not match the factored form of the polynomial.
B. F(x) = (x - 3)(x + 1 + i)(x + 1 - i)
f(x)=(x-3)(x²+2x+2)
When solve for x using quadratic formula fo x in (x²+2x+2):
x=(-b±√b²-4ac)/2a
x=-1±i
f(x)=(x-3)(x+1-i)(x+1+i)
So, the is the required factored form.
C. F(x) = (x - 3)(x + 1 + i)(x - 1 - i)
This option does not match the factored form of the polynomial.
D. F(x) = (x + 3)(x + 1 + i)(x + 1 - i)
This option does not match the factored form of the polynomial.

Suppose that PR=47. Solve for x and find the lengths of PQ, and QR.
Please show all work and not just the answers.
Answer:
x = 10
PQ = 27
QR = 20
Step-by-step explanation:
You can add up PQ and QR and set it equal to PR. Solve for x.
(2x + 7) + (2x) = 47
2x + 7 + 2x = 47
4x + 7 = 47
(4x + 7) - 7 = 47 - 7
4x = 40
4x/4 = 40/4
x = 10
Now, use the solved x-value to find PQ and QR.
PQ = 2x + 7
PQ = 2(10) + 7
PQ = 20 + 7
PQ = 27
QR = 2x
QR = 2(10)

How does the experimental probability of choosing a yellow tile compare with the theoretical probability of choosing a yellow tile
Answer:
The experimental probability is the same as the theoretical probability.
Step-by-step explanation:
The given data is:
color observed frequency relative frequency
Red 15 3/10
Blue 12 6/25
Green 8 4/25
Yellow 10 1/5
Purple 5 1/10
The experiment was repeated 50 numbers of times.
Solution:
Theoretical probability is basically what is expected to happen without experimenting and experimental probability is what actually happens as a results of an experiment.
Theoretical probability = favorable outcomes / all possible outcomes
Experimental probability = no. of times outcome occurs / no. of times
experiment is performed The experimental probability and theoretical probability are same i.e. 1/5
This can be seen from the table:
Experimental probability = 1/5
As the experiment is performed 50 times and the outcome (yellow tile) occurs 10 times so using the formula of experimental probability:
10/50 = 1/5
Now as given, there are 5 number of tiles (red,blue,green,yellow,purple) so number of possible outcomes is 5. Yellow tile among these 5 tiles is 1. So the favorable outcomes is 1. So looking at the given formula of theoretical probability:
1/5
So
experimental probability = 1/5
theoretical probability = 1/5
Hence the experimental probability is the same as the theoretical probability.

Set the two sides equal to each other and solve for x!
① -2x + 81 = 61
② 9x - 58 = 5
③ 21 + 10x = 3x + 28
④ 9x - 42 = 2x
(I already put them in the correct forms based on each images But here's the images anyways, just in case.)
Answer:
1. x = 10 2. x = 7 3. x = 1 4. x = 6
Explanation:
1. -2x + 81 = 61 (Subtract 81 from 61)
-2x = -20 (Divide)
x = 10
2. 9x - 58 = 5 (Add 58 to 5)
9x = 63 (Divide)
x = 7
3. 21 +10x = 3x + 28 (Rearrange expression)
21 - 28 = 3x - 10x (Combine like terms)
-7 = -7x (Divide)
x = 1
4. 9x - 42 = 2x (Rearrange)
9x - 2x = 42 (Combine like terms)

Hi May I know how to solve this?
Answer:
k = 3/4
Step-by-step explanation:
Parallel lines have the same slope so first, we need to find the slope of 8x + 6 = 2y. To do so, we can do the following:
8x + 6 = 2y
2y = 8x + 6
y = 4x + 3 (This is now in slope intercept form - y = mx + b where m = slope and b = y-int.)
Therefore, the slope is 4. Now, we can do:
3x = ky - 10
3x - 10 = ky
(3x / k) - (10 / k) = y
y = (3x / k) - (10 / k) (where k ≠ 0)
Now that the second line is in slope-intercept form, we can set the two x terms equal to each other, therefore:
3x / k = 4x
3x = 4x * k
3x / 4x = k
k = 3/4

Work Shown:
d = distance between (-3,1) and (5,-2)
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-3-5)^2 + (1-(-2))^2}\\\\d = \sqrt{(-3-5)^2 + (1+2)^2}\\\\d = \sqrt{(-8)^2 + (3)^2}\\\\d = \sqrt{64 + 9}\\\\d = \sqrt{73}\\\\d \approx 8.5440037\\\\d \approx 8.5\\\\[/tex]
Alternatively, you can plot the two points on the same xy grid. Then form a right triangle with the two points as the endpoints of the hypotenuse. Use of the pythagorean theorem will result in getting the same approximate distance. The distance formula is effectively the same as the pythagorean theorem, but just in a different form.

Answer:
(a) aₙ = 22 + 6(n - 1)
(b) The 14th row has 100 seats
Step-by-step explanation:
1. (a) Remember that an arithmetic series has the general formula a + (n - 1)d. Here a = the first term, and d = difference between first and second term, or in other words the difference between the nth and (n + 1)th terms.
aₙ = 22 + 6(n - 1)
This is our iterative rule for this arithmetic series, aₙ = 22 + 6(n - 1).
(b) Here n = the row number. We want to know the row number that has 100 seats. Let's equate the expression '22 + 6(n - 1)' to 100, and solve for n.
100 = 22 + 6(n - 1),
100 = 22 + 6n - 6,
100 = 16 + 6n,
6n = 84,
n = 84 / 6 = 14
=> the 14th row has 100 seats
