Answer:

C(-1)= -5

Step-by-step explanation:

This question asks us to find C(-1). We know what C(x) is, it is:

C(x)=-4x^{2} +4x+3

Therefore, we must substitute -1 in for every x to find C(-1).

C(-1)=-4(-1)^{2} +4(-1)+3

Now, solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

First, evaluate the exponent.

-1^2=-1*-1=1

C(-1)=-4(1) +4(-1)+3

Next, multiply -4 and 1.

C(-1)=-4+4(-1)+3

Multiply 4 and -1 again.

C(-1)=-4+ -4 + 3

Add the numbers together.

C(-1)=-8+3

C(-1)=-5

Hey there! :)

Answer:

C(-1) = -5.

Step-by-step explanation:

C(x) = -4x² + 4x + 3

Plug in -1 for x to solve for C(-1):

C(-1) = -4(-1)² + 4(-1) + 3

Simplify:

C(-1) = -4 + (-4) + 3

C(-1) = -5

A man selling computer parts realizes that when he sells 16 computer parts, his earning is $1700. When he sells 56 computer part
natta225 [31]

We need to find the unit rate. To do so, divide the amount of money he makes by the number of parts sold. 1,700 / 16 = 106.25. So, if the man sells one computer part, he gets $106.25. To find the price of 30 parts, multiply 106.25 by 30. 106.25 * 30 = $3,187.50

The man will make $3,187.50 if he sells 30 parts.
