The answer is 97, because when you add up 42 and 55 you get 97. Then you subtract that by 180 because a triangles angles add up to 180. 180-97=83. Z=83. Z and y are supplementary to eachother, so therefore 180-83= 97. Supplementary means they add up to 180.
Answer:
The price of a 2,000 square foot home is 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
Let
x -----> the total area of the house in square feet
y -----> the price of the house
we have
The point (1,500,300,000)
Find the constant of proportionality k

substitute

The direct equation is equal to

so
For 
Find the value of y
substitute the value of x in the equation


Answer:
4(x-7)^2-(x-7)+3 (Assuming t is f)
Step-by-step explanation:
Let s(x)=x-7 and t(x)=4x^2-x+3 .
(t o s)(x)=t(s(x))=t(x-7)
Before I continue this means replace the orginal x in t with x-7.
This will then give you
4(x-7)^2-(x-7)+3
Answer:

Step-by-step explanation:
What if i say NO?
jk
3*3=9
8+3=11
12-3=9
sp
9*11=99
2 area coverd so far
99+9=108
7*2=14
108+14=122
Lastly the tir
10-7=3
11-3-2=6
6*4=24
24/2=12
