Maxine is buying extra pages for her photo album. Each page holds exactly 8 photos. Sketch a graph to show the maximum number of

erastovalidia [21]

Ok so I can't sketch a graph for you because I don't know how to but i can give a formula that will help you graph it on your own. The equation is y = 8x having x represent the amount of extra pages you want to add. I came to this equation because if 8 photos can fit in each extra page and x represents the the extra pages then 8 photos is the slope for the equation y = mx + b. So if you were to graph this you will get a continuous line because it has no holes.

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (-1.25, -18.5)

Point (0.25, -30)

Step 2: Find slope m

Substitute: $m=\frac{-30+18.5}{0.25+1.25}$
Add: $m=\frac{-11.5}{1.5}$
Divide: $m=\frac{-23}{3}$

PLS HELP!! If f(x) = 2x^2-4x and g(x) =5-2x, evaluate f(x)-g(x) for x=5

anastassius [24]

To solve this equation you need to first start by writing out the f(x)-g(X).
The equation should be 2x^2-4x-5+2x.
You then want to simplify the equation, I got 2x^2-2x-5.
You then want to plug in the x=5 for all the x's in the equation.
2(5)^2-2(5)-5 would be the equation.
The answer you get should be 35.

Cheryl plans to bake cookies tomorrow and needs to purchase chocolate chips and pecans for no more than $25 total. Chocolate chi

boyakko [2]

The inequality that correctly represents this scenario is given as follows:

$2x + 5y \leq 25$

The graph is given at the end of the question.

<h3>What is a system of inequalities?</h3>

A system of inequalities is when two or more variables are related, and inequalities are built to find the values of each variable.

In this problem, the variables are given as follows:

Variable x: number of chocolate chips purchased.

Variable y: number of pecans sold.

Chocolate chips are $2 per pound and pecans are $5 per pound. She wants to spend at most $25, hence:

$2x + 5y \leq 25$
