Answer:
sides are 17 cm and 27 cm
Step-by-step explanation:
let the side be x then the adjacent side is x + 10
The perimeter is then
x + x + x + 10 + x + 10 = 88, that is
4x + 20 = 88 ( subtract 20 from both sides )
4x = 68 ( divide both sides by 4 )
x = 17
and x + 10 = 17 + 10 = 27
The sides of the parallelogram are 17 cm and 27 cm
Jill is buying new appliances. The cost of the dishwasher is $459 and the cost of the microwave is $289. What is the total price including the sales tax of 7%?
Answer:
$800.36
Step-by-step explanation:
429+289=748
7% of 748= 52.36
748 + 52.36=800.36
The total price of the dishwasher and microwave after the sales tax of 7% will be $800.36.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Jill is buying new appliances.
The cost of the dishwasher is $459 and the cost of the microwave is $289.
The total amount of the dishwasher and microwave will be
Total amount = 459 + 289
Total amount = $748
Then the price of the dishwasher and microwave after the sales tax of 7% will be
Total price = 7% of $748
Total price = 1.07 x $748
Total price = $800.36
Then the total price of the dishwasher and microwave after the sales tax of 7% will be $800.36.

The graph of a function f is shown below. Use the zeros and the turning points of the graph to find the rule for f.
A.
f(x) = x4 − 8x2 + 16
B.f(x) = −x4 + 5x2 − 4
C.f(x) = x3 + x2 − 4x + 4
D.f(x) = x4 − 5x2 + 4
Answer:
Answer is D
Step-by-step explanation:
Using the zeros of the graph we should have y=0 when we put x=-2, x=-1, x=1, x=2
Only the function on option D works, so the answer is D

Which of the following statements is correct?
A x is 3/4 of y
B y is 1/3 of x
c x is 1/3 of y
D y is 1/4 of x
Answer:
y is 1/3 of x
Step-by-step explanation:
x:y is 3:1
mathematically, we have this as;
x/y = 3/1
x = 3y
or y = x/3
So the correct answer is that y is 1/3 of x

[tex]f(x) = \frac{ {2}^{x} }{x} [/tex]
Consider each terms for both numerator and denominator.Numerator
[tex]y = {2}^{x} [/tex]
The function family is exponential when separating the denominator out of numerator.
Exponential family have the equation of
[tex]y = {a}^{x} [/tex]
Denominator
[tex]y = x[/tex]
The function family is linear when separating the numerator. The equation for linear family is only
[tex]y = mx + b[/tex]
We combine both exponential and linear by dividing the exponential with linear.
AnswerWe divide the exponential function by a linear function.PLSSS HELPPP. What is the domain and range of the relation {( -4,2), (-9,-5),(-4,12),(8,-8)}

Answers:
x = 4AB = 36BC = 36AC = 36All three sides are 36 units long.
===========================================================
Explanation:
Triangle ABC is equilateral, so all three sides are the same length.
Pick any two of those sides, set them equal to each other, and solve for x
AB = BC
8x+4 = 11x-8
8x-11x = -8-4
-3x = -12
x = -12/(-3)
x = 4
Use this x value to find each side. We should get the same value (if not, then an error occurred in solving for x).
AB = 8x+4 = 8*4+4 = 32+4 = 36BC = 11x-8 = 11*4-8 = 44-8 = 36AC = 9x = 9*4 = 36We get the same value for the three side lengths, so this confirms we have the correct x value.

What is the height ?
The height of the rectangular prism will be 9 cm.
What is the volume of the rectangular prism?Let the prism with a length of L, a width of W, and a height of H.
Then the volume of the prism is given as
V = L x W x H
We know that the product of the length and width will be known as the base area.
Then the volume of the rectangular prism will be
V = A x H
Base area = 147 cm²
Volume = 1323 cm³
Then the height of the rectangular prism will be
1323 = 147H
H = 9 cm
The height of the rectangular prism will be 9 cm.

Perform the indicated operation. State the domain restrictions
Answer:
c
Step-by-step explanation:
Answer:
Step-by-step explanation:
Domain has all values of x ( think X marks the spot on your domain) so the restrictions come in those cases from the fact that a fraction can NOT have the denominator 0 because dividing by 0 is not allowed.

here x+1 [tex]\neq[/tex] 0 and x+3 [tex]\neq[/tex] 0 so the domain restrictions are x [tex]\neq[/tex] -1 and x[tex]\neq[/tex] -3
to solve you need to factor x^2 -6x-27
you can do it by using
x^2 - Sx +P = 0 where S= root 1 +root 2 and P = root 1*root2
so in our case Sum has to be 6 and Product -27, what 2 numbers add to 6 and their product is -27? ....-3 and 9; S= -3+9 = 6 and P= -3*9 = -27
it will factor in (x-root 1) (x-root 2)
x^2 -6x-27 = (x+3)(x-9)
[tex]\frac{(x+3)(x-9)}{x+1} * \frac{x+1}{x+3} =\\[/tex]
