Answer:
A) x = 2, x = 7
Step-by-step explanation:
x^2 + 14 = 9x
Subtract 9x from each side
x^2-9x + 14 = 9x-9x
x^2-9x + 14 = 0
What 2 numbers multiply to 14 and add to -9
-7*-2 = 14
-7+-2 = -9
(x-7)(x-2) = 0
Using the zero product property
x-7 = 0 x-2 =0
x=7 x=2

Answer:
y = -4x - 2
Step-by-step explanation:
This line y= -4x-5 has slope = -4
Parallel line, slope is the same so slope of the new line is also = -4
Passes through the point (-2,6), equation:
y - 6 = -4(x + 2)
y - 6 = -4x - 8
y = -4x - 2
Answer:
y = -4x - 2
