Answer:
7,7
Step-by-step explanation:
A vertex should be connected, so 7 as the x makes the most sense
N=28
cross multiply 7 and 36
cross multiply 9 and n
7x36=252
9xN=9n
9n=252
—- ——
9 9
n=28
Answer:
16 feet
The length and the feet long are the same thing in this situation.
Answer:
see explanation
Step-by-step explanation:
let y = f(x), then
y = 11x - 1
Interchange x and y and solve for y
x = 11y - 1 ( add 1 to both sides )
x + 1 = 11y ( divide both sides by 11 )
y = 
, hence
(x) =
P(x) = (x^2)(x - 4)^2(x + 4) + some constant(b)
2025 = (1^2)(1 - 4)^2(1 + 4) + b
2025 = 45 + b
b = 1980
Complete Equation:
p(x) = (x^2)(x - 4)^2(x +4) + 1980
or expanded form
p(x) = x^5 - 4x^4 - 16x^3 + 64x^2 + 1980
