As a first step in solving the system shown, yumiko multiplies both sides of the equation 2x – 3y = 12 by 6. by what factor should she multiply both sides of the other equation so that she can add the equations and eliminate a variable?

Suppose that Yumiko has the linear system

Since she multiplies the first equation by 6 then she obtains the equation

Then, if she want to eliminate the variable y, she should multiply the equation (2) by because when performing the multiplication, the coefficient that accompanies the x become 12.

If she want to eliminate the variable y, she should multiply the equation (2) by because when performing the multiplication, the coefficient that accompanies the y become 3.

you answer is a

step-by-step explanation:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
