When Sylvie verified the solution on a graph, the lines intersected at one point. What was her error? She forgot to put both equations in slope-intercept form.
She made an arithmetic mistake in the last step.
She found the incorrect value of x.
She did not substitute the value of x into one of the original equations to find y.

i think c. but don't trust it.

step-by-step explanation:

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

ok then what happened.

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
