Answer:
x + 7
Step-by-step explanation:
x2 + 4x − 21
set equal to 0
x2 + 4x − 21 = 0
factor
(x - 3) (x + 7)
x2 + 11x + 28
set equal to 0
x2 + 11x + 28 = 0
factor
(x + 4) (x + 7)
Answer:
Not sure!
Step-by-step explanation:
The correct answer is x+b/a
f^{-1}(x)=\frac{x+b}{a}
Answer:
(21, 5)
Step-by-step explanation:
y = -x
y = -(-7)
y = 7
The point is reflected, so it is equidistant on both sides of the reflection line. It takes 14 units to get to the reflection line, -7 + 14 = 7 (the reflection line).
So, another 14 on the other side would be 14 + 7 = 21
