20 weeks
Step-by-step explanation:
This question, luckily, can be solved with a very simple algebraic expression.
Let w = the amount of weeks.
So from here, we need to divide both sides by 25 to get w by itself:
Therefore, it will take Aubree 20 weeks to have enough money to buy the computer.
Slope-intercept from: y = mx +c
Here, m is the slope & c is the y-intercept.
So, we have to isolate y. To isolate y first subtract 2x from both sides.
2x - 3y = -9
-3y = -2x -9
Now, divide the entire equation by the co efficient of y (-3)
