Answer:
x=8
Step-by-step explanation:
(6x+4)+(4x+6)=90
10x+10=90
-10 -10
<u>10x</u>=<u>80</u>
10 10
x=8
Line m has no y int....so it does not cross the y axis....this means it is a vertical line with its equation being : x = 3.
line n has no x int...so it does not cross the x axis...means it is a horizontal line with its equation being : y = -4
Factor out the common term 6m
6m(m + 2) = 0
Solve for m
<em>When will m(m + 2) equal zero?</em>
When m = 0 or m + 2 = 0
Solve each of the equations above
<u>m = 0, -2</u>
Well you divide the 75 percent and the 18 and you will get your answer
