F(x) = -7x + 5x² + 10
x = -2
substitute the x by its value
f(-2) = -7(-2) + 5(-2)² + 10
f(-2) = 14 + 5(4) + 10
f(-2) = 14 + 20 + 10
f(-2) = 44
X = 32
Y = 8
Hope this helps!
Answer: a) reflected over x-axis and reflected over y-axis
<u>Step-by-step explanation:</u>
Reflection over the x-axis changes the sign of the y-coordinate
Z = (x, y) → Z'(x, -y)
Reflection over the y-axis changes the sign of the x-coordinate
Z' = (x, -y) → Z''(-x, -y)
A = (-4, 1) → A'' = (4, -1)
B = (-3, 2) → A'' = (3, -2)
C = (-1, 2) → A'' = (1, -2)
D = (-2, 1) → A'' = (2, -1)
-2 = 3x/5 + 1
-2 - 1 = 3x/5
-3 = 3x/5
-3 * 5 = 3x
-15 = 3x
x = -15/3
x = -5
<span>Multiply the number by the percent (e.g. 87 * 68 = 5916)Divide the answer by 100 (Move decimal point two places to the left) (e.g. 5916/100 = 59.16)<span>Round to the desired precision (e.g. 59.16 rounded to the nearest whole number = 59)</span></span>
