Answer:

<h3>Combine like terms onto one side of the equation</h3>

Step-by-step explanation:

Given the first step in determining the solution to the system of equations,

y = –x2 – 4x – 3 and y = 2x + 5, algebraically as setting the two equations equal as shown:  –x2 – 4x – 3 = 2x + 5, <u>the next step will be to combine like terms onto one side of the equation. The like terms are the terms containing the variable x </u>as shown;

-x²-4x-2x = 5+3

As we can see, <em>the term containing x in the right hand side of the equation (i.e 2x) are being brought to the left side of the equation.</em> This will be the next step in the calculation

Out of a total of 3000 available parking spaces in a mall
guajiro [1.7K]

Answer:

62.5% of the parking spaces are taken.

Step-by-step explanation:

Given

  • Total Spaces = 3000
  • Taken paces = 1875

To determine

What percent of the parking  spaces are taken?

The percentage of taken spaces of the part can be determined using the formula

% of Taken spaces = [Taken spaces / Total Spaces ] × 100

                               = [1875 / 3000] × 100

                               = 0.625 × 100

                               = 62.5%

Therefore, 62.5% of the parking spaces are taken.

For the following exercises, evaluate the expressions, given functions f, g, and h:
sertanlavr [38]

Answer:

- 16

Step-by-step explanation:

Evaluate f(2) by substituting x = 2 into f(x) , that is

f(2) = 3(2) - 3 = 6 - 3 = 3

Evaluate g(- 1) by substituting x = - 1 into g(x) , that is

g(- 1) = 8 - (- 1)² = 8 - 1 = 7

Thus

4f(2) - 4g(- 1)

= 4(3) - 4(7)

= 12 - 28

= - 16
