Answer:
Your answer is 65
Step-by-step explanation:
f(x) = x² - 4x - 12
f(-7) = (-7)² - 4 x (-7) - 12
= 49 - (-28) - 12
= 49 + 28 - 12
= 77 - 12
= <u>65</u>
3 divided by 64 is 0.046875

Answer:
<h3>
R(-1, -9)</h3>
Step-by-step explanation:
When we reflect over x-axis then the x-coordinate doesn't change and the y-coordinate changes its sign
in means if R = (x, y) then R' = (x, -y)
so we have:
x = -1 and -y = 9
y = -9
which gives R = (-1, -9)
