Answer:

x = -7, -3

Step-by-step explanation:

Try to factor the left side of the equation.

(x +7)(x + 3) = 0 Remember that if AB = 0, then A = 0 or B = 0 or both A and B = 0

Therefore, x + 7 = 0 or x + 3 = 0

x = -7 or x = -3

True or false?is the point(16,4) included in this function: Y=2x or Y=x2 or y= x+12 or y=x-12

Gelneren [198K]

Answer:

True

Step-by-step explanation:

It is true because the graph of $y=x-12$ passes through the point $(16,4)$

x = 16

y = 4

Substitute

4 = 16 - 12

4 = 4

Therefore, the answer is true.
