1. Graphs help you solve equations, and equations help you solve graphs. Because <span>the graph is a diagram of the equation, showing at its simplest the y answer for each value of x.
2. </span>You have to solve for y, graph it, and then find where the lines intersect.You can take a table and put in all the x and y values. Then you graph it.. And see where it intersects because usually these equations are lines. Also you'd wanna solve for slope-intercept form(y = mx + b)

I need help it’s a quiz
solmaris [256]

Answer:

Question 6: 26 crowns plus 15 ribbons.

Question 7: 10 footballs plus 42 basketballs.

Step-by-step explanation:

Question 6 explanation: Since the expression is 22 crowns plus 13 ribbons plus 2 ribbons plus 4 crowns, you can think of the different items as variables in an equation. Picture crowns are the variable x, and ribbons as the variable y, this will help you solve the equation in an easier way that allows you to comprehend each step better. The equation will now be 22x+13y+2y+4x, in order to find how many x (crowns) and y (ribbons) you have, you need to combine like terms in the expression. In other words, add the terms with the variable x together, and add the terms with the variable y together. Simplified, the equation will be 26x+15y. Since the variables x and y were used to represent crowns and ribbons respectively, that means the correct answer is 26 crowns plus 15 ribbons.

Question 7 explanation: You can use the same method as you did in question 6, think of footballs and basketballs as the variables x and y respectively. The equation will be 16x+38y-6x+4y = 10x+42y. Since the variable x was used to represent footballs and the variable y was used to represent basketballs, that means the correct answer would be 10 footballs plus 42 basketballs.
