Answer:
(-1,3)
Step-by-step explanation:
–2x – 9y=-25
-4x – 9y=-23
Multiply the second equation by -1
4x + 9y=23
Add this to the first equation
–2x – 9y=-25
4x + 9y= 23
-----------------------
2x = -2
Divide each side by 2
2x/2 = -2/2
x = -1
Now we need to find y
4x+9y = 23
4(-1) +9y = 23
-4 +9y = 23
Add 4 to each sdie
-4+4 +9y = 23+4
9y = 27
Divide each side by 9
9y/9 = 27/9
y =3
Answer:
A
Step-by-step explanation:
We know that the growth of a linear function will always be constant. So, that eliminates B and C.
A quadratic function can be a function such as 
, or 
, etc.
An exponential function wouldn't be , it would be 
! Or 
, or 
, etc. Therefore, D is eliminated.
So, the answer is 
and we're done!
Step-by-step explanation:
7p – 3q
if p= 8 and q = -5
7(8)-3(-5)
56+15
=71
