Sometimes the best way to solve an equation, a system of equations, or a system of inequalities is to look at a graph of the equ

ation or the system. Finding solutions on graphs is different from using algebraic properties to solve for a variable, but it gives the same results. For each of the three graphs, describe how and why the graph shows the solutions of the equation or system of equations or inequalities.

Answer:

When we solve a system of equations, we are looking for the points at which both graphs intercept. Solving a system of equations sometimes can be hard, and you should use other methods -Like numeric methods- to solve it. That's why sometimes is easier to look at the graph of the equation.

To solve a equation, system of equations or a system of inequalities, we should graph each of the equations separatedly, and the result will be the point at which the functions intercept or a single function intercepts the x-axis.

If the function does not intercept another function or the x-axis, then it has no real roots. The number of solutions an equation can have, will depend on the degree of the equation.

Steve sold 36 fruit baskets for a school fundraiser. Evie sold 25% of the number of baskets that Steve sold. How many fruit bask
xeze [42]

Answer:

9 fruit baskets.

Step-by-step explanation:

Given:

Steve sold 36 fruit baskets for a school fundraiser.

Evie sold 25% of the number of baskets that Steve sold.

<u>Question asked:</u>

How many fruit baskets did Evie sell?

Solution:

<u>As given that Evie sold 25% of the number of baskets that Steve sold.</u>

Number of baskets sold by Evie = 25% of 36

                                                      =\frac{25}{100}\times36\\\\  =\frac{900}{100}\\ \\=9

Thus, 9 fruit baskets sold by Evie.

A salsa recipe uses green pepper, and onion, and tomato in the extended ratio 2:5:9. How many cups of onion are needed to make 9
Vlad1618 [11]
The answer is 30 cups

Let x be a multiplier. So:
2x + 5x + 9x = 96
16x = 96
x = 96/16
x = 6 cups

Since the number of onion cups is 5x, then 5 * 6 = 30 cups are needed to make 96 cups of salsa.

A tumor in a rat responds to a new radiation treatment by shrinking 5% with each treatment. How many treatments before the tumor
Nuetrik [128]
A quarter of its original size would be 25% of 100%, right? Therefore, the tumor would have to shrink 75%. If each treatment, the tumor shrinks 5% that would mean it takes 15 treatments to shrink 75 percent. 

If this helped, please thank, rate, and give brainliest answer!
