The profit from a business is

GuDViN [60]

First of all we will understand the question!!

The question is saying that you are given a function and you have to find the value of x which will give the maximum profit... Lets solve it by finding the extrema using the vertex

 $\rm \: p(x) = - 5 {x}^{2} + 30x + 8$ 

Identify the coefficients a and b of the quadratic function

 $\rm \: p(x) = { - 5x}^{2} + 30x + 8 \\ \rm \: a = - 5 \: and \: b \: = 30$ 

Since a<0, the function has the maximum value at x, calculated by substituting a and b into x=-b/2a

$\rm \: x = \frac{30}{ 2 \times (- 5)}$

Solve the equation for x

$\rm \: x = 3$

The maximum of the quadratic function is at x=3

Which number(s) could you place in the equation below to create an equation with infinite solutions? Select all that apply.

Vilka [71]

Answer:

d.) 2

Step-by-step explanation:

If you were going to solve the second part of the equation you would distribute and since we want the number we chose to equal 8, so the sides will be equivelent and their will be infinite solutions, we have to account for the *4 so if we do 8 ÷ 4 we will have the number we should use for infinite solutions

8÷4=2

You can also check it by putting 2 in the equation

4x + 8 = 4(x+2) now distribute the 4

4x+8=4x+8
