f(x) = x² - 8x + 5 Plug in -1 for all of the x-values
f(-1) = (-1)² - 8 (-1) + 5 Square -1
f(-1) = 1 - 8 (-1) + 5 Multiply -8 and -1
f(-1) = 1 + 8 + 5 Add
f(-1) = 14
Answer: X = -10
Step-by-step explanation:
Times two to the parentheses
Minus X from both sides, left with 3X-16=-46
Add 16 to both sides 3X=-30
Divide both sides by 3
Answer X=-10
The correct answer is ∠Y = 75°
because
45°∠A ∼ ∠X
∠B ∼ ∠Y = 75°
60°∠C ∼ ∠Z
45 + 60 = 105
180 -105 = 75
Answer:
10
Step-by-step explanation:
12(10)=120+30 or 150-30=120=12(10)
The equation is
x2 - 3 = y
