Answer: translation 8 units to the right
Step-by-step explanation:
An even function is a function such that:
h(x) = h(-x)
and the function is odd if:
h(-x) = -h(x)
Now, let's talk about transformations:
A) Reflection over the x-axis:
When we have a point (x,y) and we do a reflection over the x-axis, the reflected point will be:
(x, -y).
Then for the case of a function:
y = h(x).
then the reflection will be:
g(x) = - y = -h(x).
And if h(x) is even, -h(x) is also even, so this is not the correct option.
B) Vertical stretch by a factor of 7.
This is written as:
g(x) = 7*h(x).
then:
g(x) = 7*h(x)
g(-x) = 7*h(-x) = 7*h(x) = g(x)
the transformation is even.
C) Translation of 8 units to the right.
We can write this as:
g(x) = h(x - 8).
Then:
g(-x) = h(-x -8) = h(x + 8)
Then g(-x) is not equal to g(x)
and also g(-x) ≠ -g(x)
So in this case the transformation is neither odd or even.
C) horizontal compression by a factor of One-half.
This transformation is written as:
g(x) = h( (1/2)*x)
And, similar as the case of the vertical compression, in this case the transformation is also even.
Answer: C
Step-by-step explanation:
Translation 8 units to the right

If a and b are the zeroes of the polynomial x2 + 5x + 8, then the value of a2 + b2
is..............(Pls help)
Answer:
9
Step-by-step explanation:
If α and β are the zeros of ax² + bx + c = 0 , then
α + β = [tex]\frac{-b}{a}[/tex] ( sum of zeros ) and
αβ = [tex]\frac{c}{a}[/tex] ( product of zeros )
Given
x² + 5x + 8 = 0
with a = 1, b = 5, c = 8 , with zeros a and b, then
a + b = [tex]\frac{-5}{1}[/tex] = - 5
ab = [tex]\frac{8}{1}[/tex] = 8
Thus
(a + b)² = a² + 2ab + b² , that is
(- 5)² = a² + 2(8) + b²
25 = a² + 16 + b² ( subtract 16 from both sides )
9 = a² + b²
true or false if a x b=0 the either a=0 or b=0 pls help!!
Answer:
yes that answer is true

Find p in the equation ( attached photo of the equation)
Answer:
p = - 14
Step-by-step explanation:
Using the rules of exponents
[tex]a^{m}[/tex] ÷ [tex]a^{n}[/tex] = [tex]a^{(m-n)}[/tex]
[tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex]
Note 81 = 9² and 729 = 9³
Given
[tex](81)^{-4}[/tex] ÷ [tex](729)^{2-p}[/tex]
= [tex](9^{2}) ^{-4}[/tex] ÷ [tex](9^{3}) ^{2-p}[/tex]
= [tex]9^{-8}[/tex] ÷ [tex]9^{6-3p}[/tex]
= [tex]9^{-8-(6-3p)}[/tex]
= [tex]9^{-8-6+3p}[/tex]
= [tex]9^{3p-14}[/tex]
Thus
[tex]9^{3p-14}[/tex] = [tex]9^{4p}[/tex]
Since bases on both sides are equal then equate the exponents
4p = 3p - 14 ( subtract 3p from both sides )
p = - 14

Elias completely covered a square canvas using 77.8 in.² of fabric without any overlap. Which measurement is closest to the side length of this canvas in inches? A. 8 in. B.9 in. C. 19 in. D. 39 in.
Answer:
B. 9 in
Step-by-step explanation:
The area covered by the fabric ([tex]A[/tex]) is represented by the following formula:
[tex]A = l^{2}[/tex]
Where [tex]l[/tex] is the side length of the canvas, measured in inches, and which is now cleared:
[tex]l = \sqrt{A}[/tex]
If [tex]A = 77.8\,in^{2}[/tex], then:
[tex]l = \sqrt{77.8\,in^{2}}[/tex]
[tex]l \approx 8.82\,in[/tex]
Which corresponds to option B.

Answer:
x = -(-30/7)^(1/25) or x = (30/7)^(1/25) or x = (-1)^(2/25) (30/7)^(1/25) or x = -(-1)^(3/25) (30/7)^(1/25) or x = (-1)^(4/25) (30/7)^(1/25) or x = -(-1)^(1/5) (30/7)^(1/25) or x = (-1)^(6/25) (30/7)^(1/25) or x = -(-1)^(7/25) (30/7)^(1/25) or x = (-1)^(8/25) (30/7)^(1/25) or x = -(-1)^(9/25) (30/7)^(1/25) or x = (-1)^(2/5) (30/7)^(1/25) or x = -(-1)^(11/25) (30/7)^(1/25) or x = (-1)^(12/25) (30/7)^(1/25) or x = -(-1)^(13/25) (30/7)^(1/25) or x = (-1)^(14/25) (30/7)^(1/25) or x = -(-1)^(3/5) (30/7)^(1/25) or x = (-1)^(16/25) (30/7)^(1/25) or x = -(-1)^(17/25) (30/7)^(1/25) or x = (-1)^(18/25) (30/7)^(1/25) or x = -(-1)^(19/25) (30/7)^(1/25) or x = (-1)^(4/5) (30/7)^(1/25) or x = -(-1)^(21/25) (30/7)^(1/25) or x = (-1)^(22/25) (30/7)^(1/25) or x = -(-1)^(23/25) (30/7)^(1/25) or x = (-1)^(24/25) (30/7)^(1/25)
Step-by-step explanation:
Solve for x:
7 x^25 = 30
Hint: | Divide by an appropriate factor to make the coefficient of x^25 equal to 1.
Divide both sides by 7:
x^25 = 30/7
Hint: | Take 25^th roots of both sides.
Taking 25^th roots gives (30/7)^(1/25) times the 25^th roots of unity:
Answer: x = -(-30/7)^(1/25) or x = (30/7)^(1/25) or x = (-1)^(2/25) (30/7)^(1/25) or x = -(-1)^(3/25) (30/7)^(1/25) or x = (-1)^(4/25) (30/7)^(1/25) or x = -(-1)^(1/5) (30/7)^(1/25) or x = (-1)^(6/25) (30/7)^(1/25) or x = -(-1)^(7/25) (30/7)^(1/25) or x = (-1)^(8/25) (30/7)^(1/25) or x = -(-1)^(9/25) (30/7)^(1/25) or x = (-1)^(2/5) (30/7)^(1/25) or x = -(-1)^(11/25) (30/7)^(1/25) or x = (-1)^(12/25) (30/7)^(1/25) or x = -(-1)^(13/25) (30/7)^(1/25) or x = (-1)^(14/25) (30/7)^(1/25) or x = -(-1)^(3/5) (30/7)^(1/25) or x = (-1)^(16/25) (30/7)^(1/25) or x = -(-1)^(17/25) (30/7)^(1/25) or x = (-1)^(18/25) (30/7)^(1/25) or x = -(-1)^(19/25) (30/7)^(1/25) or x = (-1)^(4/5) (30/7)^(1/25) or x = -(-1)^(21/25) (30/7)^(1/25) or x = (-1)^(22/25) (30/7)^(1/25) or x = -(-1)^(23/25) (30/7)^(1/25) or x = (-1)^(24/25) (30/7)^(1/25)

d = b^2 -4ac solve for a 2/3 (x-18y) = 6y solve for x
Answer:
a = [tex]\frac{b^2-d}{4c}[/tex]
x = 27y
Step-by-step explanation:
Order of Operations: BPEMDAS
Question 1
Step 1: Write out discriminant
d = b² - 4ac
Step 2: Subtract b² on both sides
d - b² = -4ac
Step 3: Divide both sides by -1
b² - d = 4ac
Step 4: Divide both sides by 4c
a = [tex]\frac{b^2-d}{4c}[/tex]
Question 2
Step 1: Write out equation
2/3(x - 18y) = 6y
Step 2: Distribute parenthesis
2/3x - 12y = 6y
Step 3: Isolate x by adding 12y on both sides
2/3x = 18y
Step 4: Divide both sides by 2/3
x = 27y
Charmaine works mowing lawns and babysitting. She earns $8.80 an hour for mowing and $8.10 an hour for babysitting. How much will she earn for 6 hours of mowing and 1 hour of babysitting?
Answer:
Charmaine earns $60.90 for 6h for mowing and 1h for babysitting.
Step-by-step explanation:
We must write the data problems.
Charmaine = $8.80/h mowing
Charmaine = $8.10/h babysitting
How much will Charmaine earn for 6 h mowing and 1 h babysitting?
1 h mowing ....................... $8.80
6 h mowing ....................... $x
x = 6 h mowing * $8.80
x = $52,8
To find the total earn of Charmaine, we have to gather the earns from mowing and babysitting.
$52,8 (from mowing) + $8.10 (from babysitting) = $60.90

Answer:
infinitely many
Step-by-step explanation:
12x + 1 = 3(4x + 1) - 2
Distribute
12x + 1 = 12x + 3 - 2
Combine like terms
12x+1 = 12x +1
Subtract 12x from each side
1 =1
Since this is always true, we have infinite solutions
Answer:
[tex]\Huge \boxed{\mathrm{infinite \ solutions}}[/tex]
Step-by-step explanation:
[tex]\sf 12x + 1 = 3(4x + 1) - 2[/tex]
Using distributive property.
[tex]\sf 12x + 1 = 12x+3 - 2[/tex]
[tex]\sf 12x + 1 = 12x+1[/tex]
Subtracting 1 from both sides.
[tex]\sf 12x=12x[/tex]
Dividing both sides by 12.
[tex]\sf x=x[/tex]

v=pi r^2 h solve for pi
please help asap
will mark brainliest
Answer:
[tex]\pi=\frac{v}{hr^2}[/tex]
Step-by-step explanation:
So we have:
[tex]v=\pi r^2h[/tex]
And we want to solve for π.
First, divide both sides by h:
[tex]\frac{v}{h}=\pi r^2[/tex]
Now, divide both sides again by r²:
[tex]\pi=\frac{v}{hr^2}[/tex]
And this is our answer :)
Answer:
[tex]\frac{v}{r^{2} h} = \pi[/tex]
Step-by-step explanation:
Simply divide both sides by [tex]r^{2}h[/tex] to get pi by itself.

Answer:
12.2 cm
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here A = 20.74 and b = 3.4 , thus
[tex]\frac{1}{2}[/tex] × 3.4 × h = 20.74 ( multiply both sides by 2 to clear the fraction )
3.4h = 41.48 ( divide both sides by 3.4 )
h = 12.2 cm
h = 12,2 cm
Step-by-step explanation:Area formula
A = b×h/2
20.74 = 3.4×h/2
41.48 = 3.4h
h = 41.48/3.4
h = 12,2 cm

which expression is equivalent to 1.5(6x+3y)+2x-0.05y?
A.11x+4.45y
B.11x+5y
C.11x+2.95y
D.9.5x+4y
Answer:
The correct option is (a).
Step-by-step explanation:
We need to find the expression that is equivalent to 1.5(6x+3y)+2x-0.05y.
Firstly opening brackets as follows :
[tex]1.5(6x+3y)+2x-0.05y=1.5\times 6x+1.5\times 3y+2x-0.05y\\\\=9x+4.5y+2x-0.05y[/tex]
Now taking x terms and y terms together
[tex]9x+4.5y+2x-0.05y=(9x+2x)+(4.5y-0.05y)\\\\=11x+4.45y[/tex]
So, 1.5(6x+3y)+2x-0.05y is equal to 11x+4.45y.
5+2x=2x+6 please answer
If we firstly consider only the terms in x.
subtract 2x from both sides of the equation
⇒5+2x
−2x=2x−2x
+6
Observe that the x terms are eliminated and we are left with
5+0=0+6 that is 5=6 which is invalid
There is no solution to this equation.
Answer:
no solution
Step-by-step explanation:
Given
5 + 2x = 2x + 6 ( subtract 5 from both sides )
2x = 2x + 1 ( subtract 2x from both sides )
0 = 1 ← not possible
Thus indicates the equation has no solution

The area of a rectangular football field is 7200m² while its perimeter is 360m. Calculate the;
dimension of the field
(60 m ; 120 m)
Step-by-step explanation:A = l×w = 7200m²
P = 2w + 2l = 360m
lw = 7200 => l = 7200/w
2(w + l) = 360 => w + l = 180
w + 7200/w = 180
w² + 7200 - 180w = 0
w² - 60w - 120w + 7200 = 0
w(w - 60) - 120(w - 60) = 0
(w - 60)(w - 120) = 0
w₁ = 60m => l₁ = 7200/60 = 120 m
w₂ = 120m => l₂= 60 m
