•How do the solutions to an equation relate to the graph of the equation?
aliya0001 [1]
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)

the basement has an area of 600 square feet the width of the basement is 2/3 length FAST I CANT FIND ONE ANSWER FOR THIS
Phantasy [73]

Answer:

length=30 ft breadth=20 ft

Step-by-step explanation:

let lenght be x then breadth will be 2/3x

now, area=lenght×breadth

=>600 =(x×2/3x)

=>600=2/3x^2

=>x^2=900

=>x=30 (ft)

now length will be 30 ft

breadth will be 30×2/3 (ft) =20(ft) ✌️
