100-64=36 percent wrong
if 36% is 18 questions
then, 36/18=2
every question is 2% grade
100/2=50 questions in total
Replace the variable x with -4 in the expression.
f (- 4) = 3(- 4)^2 - (- 4) + 23
Simplify each term.
f (- 4) = 48 + 4 + 23
Simplify by adding numbers.
f (- 4) = 75
The final answer is 75.
Answer:
Step-by-step explanation:
slope = y₂ - y₁ / x₂ - x₁
= 6 - [-1] / -8-10
= 6 + 1 / -8-10
= 7/ - 18
= - 7/18
