f(x) = 2x - 1 , x= 1/2, - 1/2
Answer:
p(1/2)= 0 , p(-1/2)= -2
Step-by-step explanation:
p(1/2)= 2(1/2)-1
= 1-1
= 0
p(-1/2) = 2(-1/2)-1
= -1-1
= -2

Answer:
10
Step-by-step explanation:
Since T is the midpoint of PQ, we know that PT = TQ, therefore:
3x + 1 = 5x - 5
-2x = -6
x = 3
Since PT = 3x + 1, the answer is PT = 3 * 3 + 1 = 10.
what situations would solve by graphing be your preferred choice? Give an example.
In what situations would solve by substitution be your preferred choice? Give an example.
In what situations would solve by elimination be your preferred choice? Give an example.
Write a linear system that can be solved by any of the three methods.
Answer:
1) The solve by graphing will the preferred choice when the equation is complex to be easily solved by the other means
Example;
y = x⁵ + 4·x⁴ + 3·x³ + 2·x² + x + 3
2) Solving by substitution is suitable where we have two or more variables in two or more (equal number) of equations
2x + 6y = 16
x + y = 6
We can substitute the value of x = 6 - y, into the first equation and solve from there
3) Solving an equation be Elimination, is suitable when there are two or more equations with coefficients of the form, 2·x + 6·y = 23 and x + y = 16
Multiplying the second equation by 2 and subtracting it from the first equation as follows
2·x + 6·y - 2×(x + y) = 23 - 2 × 16
2·x - 2·x + 6·y - 2·y = 23 - 32
0 + 4·y = -9
4) An example of a linear system that can be solved by all three methods is given as follows;
2·x + 6·y = 23
x + y = 16
Step-by-step explanation:
What are the two solutions to the absolute value equation |2x+3|=7
Step-by-step explanation: We can solve the equation |2x + 3| = 7 by
first splitting things up into two separate equations.
The first equation will look just like the original problem,
minus the absolute value signs and we have 2x + 3 = 7.
The second equation will look just like the first, only the right
side will be changed to a negative and we have 2x + 3 = -7.
Now solve each equation from here.
In our first equation, subtract 3 from both sides to get 2x = 4.
Then divide both sides by 2 and x = 2.
In our second equation, subtract 2 from both sides to get 2x = -10.
Now, divide both sides by 2 and we have x = -5.
So either x = 2 or x = -5.

zero equals four plus n over 5
Answer:
n=-20
Step-by-step explanation:
[tex]0 = 4 + \frac{n}{5} \\ ⟶ 0 - 4 = \frac{n}{5} \\ ⟶ - 4 \times 5 = n \\ ⟶ - 20 = n[/tex]
Answer:
-20
Step-by-step explanation:
Zero equals four plus n over 5
Solving for n:
0 = 4 + n/5n/5 + 4 = 0n/5 = -4 ⇒ subtract 4 from both sidesn = -4*5 ⇒ multiply by 5 both sidesn = -20 ⇒ answerWrite the set of all real numbers except 100 in set builder notation. PLEASE ANSWER FAST

Step-by-step explanation:
The set of all real numbers except for 100 in set builder notation (assuming the variable is x) is:
[tex]\{x|x\in\mathbb{R},x\neq100\}[/tex]
The very first x represents the variable.
The second with the R represents the number. Here, we want all real numbers.
And the third is the constraint. We want all real numbers except for 100.

PLEASE HELP BRAINLIEST FOR WHOEVER ANSWERS CORRECTLYYYYYYYYYYYYYYY the perimeter P of a square is four times the length of one side s, which can be expressed as P = 4s. is (13,51) a solution of this equation? if not, find a solution that uses one or the other of the given values
Answer:
No, but (13,52) is
Step-by-step explanation:
To find this you need to understand what (13,51) means.
13 = x coordinate
51 = y coordinate
If you plug 13 into the equation given (P = 4s) you get 52. Therefore, (13,51) is not a solution but instead (13,52) is.
This means each of the four sides has a length of 13 units.
I hope this helps!
-TheBusinessMan
Answer:
P = 52
Step-by-step explanation:
51 = 13(4) 13x4=52
51 does not equal 52 there fore those values are immensely incorrect. However you may state 52 as the perimeter therefore allowing 52 1to equal 13(4).
New solution 52 =13(4)
nwhat is the range of data set for 8 1 7 6 14
Answer:
14-1=13 range= 13
Step-by-step explanation:
The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.
Find how much interest $10,000 earns in 2 years in a certificate of deposit paying 8.5% interest compounded quarterly
The interest earned in 2 years is $
Answer:
Interest earned in two years is approximately $1,837
Step-by-step explanation:
A= P( 1+r/n)^nt
Where,
A= principal + interest
P= principal= $10,000
r= interest rate = 8.5%
t= Time = 2years
n = periods = 4
A= P( 1+r/n)^nt
= 10,000(1+0.085/4)^4*2
= 10,000( 1 + 0.0213)^8
= 10,000(1.0213)^8
= 10,000(1.1837)
=11,837
A= $11,837
The interest earned in two years is
A = p + I
A - P = I
$11,837 - $10,000 = I
$1,837 = I
I= $1,837
Interest earned in two years is approximately $1,837

Creating a Function from a Mapping The mapping shows a relationship between input and output values. Which ordered pair could be removed to make this relation a function? Input Output O (-5, 0) O (-1, -3) -5 O (4, -2) 2 -3 O (6,-1) -1 -2 ī ņ ņ na v v • 4 2 6
I'm not sure what some of the ordered pairs are in what you wrote, but a function is when each input has one output. So, for every x there is one y. The x values can not repeat. So, remove one of two ordered pairs where the x value is repeating.

Simplify the rational expression(picture and choices attached)! 15 points and will give Brainliest. Due soon.
Answer:
The answer should be:
[tex]=\frac{8x^3-18x}{3x+2}[/tex]
The closest answer is A, so I'll go with that.
Step-by-step explanation:
So we have the rational expression:
[tex]\frac{4x^3-9x}{2x-7}\div\frac{3x^2+2x^2}{4x^2-14x}[/tex]
First, remove the division sign. To do so, turn the division into multiplication and flip the second term:
[tex]\frac{4x^3-9x}{2x-7}\cdot \frac{4x^2-14x}{3x^2+2x}[/tex]
Now, simplify. From the first term, in the numerator, factor out a x. On the second term, factor out a 2x in the numerator and a x in the denominator:
[tex]\frac{x(4x^2-9)}{2x-7}\cdot\frac{2x(2x-7)}{x(3x+2)}[/tex]
Multiply straight across:
[tex]\frac{x(4x^2-9)(2x)(2x-7)}{(2x-7)(x)(3x+2)}[/tex]
Cancel out the (2x-7):
[tex]\frac{x(4x^2-9)(2x)}{x(3x+2)}[/tex]
Cancel out the x:
[tex]\frac{(2x)(4x^2-9)}{(3x+2)}[/tex]
At this point, we can factor the (4x^2-9) term, but we won't be able to cancel it out. Thus, this is the simplest it can get.
To get the answer, expand the numerator:
[tex]=\frac{8x^3-18x}{3x+2}[/tex]
Thus, the answer is...
A?
Answer:
The right solution is option a : [tex]\frac{8x^2 - 18}{3x+2}[/tex]
Step-by-step explanation:
We have to simplify the following rational expression,
[tex]\frac{4x^3-9x}{2x-7}[/tex] ÷ [tex]\frac{3x^3+2x^2}{4x^2-14x}[/tex]
Take into account the rule (a / b) / (c / d) = ad / bc. This simplifies the expression a bit further --- (1)
[tex]\left(4x^3-9x\right)\left(4x^2-14x\right)[/tex] ÷ [tex]\left(2x-7\right)\left(3x^3+2x^2\right)[/tex]
Let's now factor each individual expression as demonstrated below. Afterwards we can substitute back into the expression above --- (2)
Goal - Factor : (4x³ - 9x)(4x² - 14x),
4x³ - 9x ⇒ x(4x² - 9)
4x² - 14x ⇒ 2x(2x - 7)
[tex]x\left(4x^2-9\right)\cdot \:2x\left(2x-7\right) = 2x^2\left(4x^2-9\right)\left(2x-7\right)[/tex]
That leaves us with the following expression,
[tex]2x^2\left(4x^2-9\right)\left(2x-7\right)[/tex] ÷ [tex]\left(2x-7\right)\left(3x^3+2x^2\right)[/tex]
As you can see the " 2x - 7 " cancel out, and the " x² " cancel as well, leaving us with a further simplified expression,
[tex]2\left(4x^2-9\right)[/tex] ÷ [tex]3x+2[/tex]
Which can also be rewritten as [tex]8x^2 - 18[/tex] ÷ [tex]3x + 2[/tex] = [tex]\frac{8x^2 - 18}{3x+2}[/tex], in other words the first option.

Perform the indicated operation. PLEASEE HELPP HURRYY!! (3 + i) + (5 + 7i) = A) -2 + 6i B) 2 + i C) 8 + 6i D) 8 + 8i
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{8 + 8i}}}}}[/tex]
Option D is the correct option.
Step-by-step explanation:
[tex] \sf{(3 + i) + (5 + 7i)}[/tex]
When there is a ( + ) in front of an expression in parentheses , there is no need to change the sign.
That means, the expression remains the same.
Just remove the unnecessary parentheses
⇒[tex] \sf{3 + i + 5 + 7i}[/tex]
Collect like terms and simplify
⇒[tex] \sf{3 + 5 + i + 7i}[/tex]
⇒[tex] \sf{8 + 8i}[/tex]
Hope I helped!
