The answer is 3x+15
You multiply the x and 5 by 3 to get 3x and 15
4y+7x-3y+2x
(7x+2x)+(4y+-3y)
=9x+y
<span>He should use the mean because there are no outliers that affect the mean.</span>
If the equation is in standard form:ax+by=c then you just set x equal to 0 to find the y intercept and set y equal to 0 to find the x intercept. It makes sense, right. The y intercept is when the line crosses the y axis, so x will always be 0, so that is why we set x equal to 0.Step-by-step explanation:
