If it is the question I just completed it should be A. 76.4
The domain is the x intercept and the y intercept is the range
Answer:
no
Step-by-step explanation:
7x+5y=15
(x,y)

N^2 - n = 90
n^2 - n - 90 = 0
(n - 10)(n + 9) = 0
n - 10 = 0
n = 10
n + 9 = 0
n = -9
answer is : n = 10 and n = -9
Answer:
(x) =

Rearrange the equation making x the subject
y = 5x + 3 ( subtract 3 from both sides )
y - 3 = 5x ( divide both sides by 5 )
= x
Change y to x then
(x) =
