Answer:
f'(1) = 2
Step-by-step explanation:
f(x) = 2x^2 -2x +3
Take the derivative
f'(x) = 2 * 2x - 2 * 1
f'(x) = 4x -2
f'(1) = 4(1) -2
=4-2
=2
To solve for a number x,
3x+4x-2=15
7x-2=15
7x=17
x=2 3/7
or x=~2.43
was one of your answer choices either of the first two equations?
Answer:
7 x p = 70
Step-by-step explanation:
7 vehicles times some number of people in each one equals 70 people in all
Hey!
b is the coefficient of x, so b= -5
a is the coefficient of x^2, so a=3
c is the constant term. So c = 5
