Step-by-step explanation:
2x^2 + 8x + 8
factor the 2 out : 2(x^2 + 4x + 4)
2(x + 2)^2
x = -2
Answer:
y = -6x — 13
Step-by-step explanation:
use y = mx + b equation and plug in what you know.
5 = -6(-3) + b —> solve for b
b = -13 —> plug in what you know into y=mx+b
ANSWER: y = -6x — 13
11 - 2/3n = 4 + n
n + 2/3n = 7
3n^2 + 2 = 21n
3n^2 - 21n + 2 = 0
n = 6.903 , n = 0.09657
