No, because if y is in fact 9 then the expression evaluates to which is a false hence y cannot be 9 but rather .
Hope this helps.
Answer:
<em><u>D</u></em>
Step-by-step explanation:
take two points from the graph to find the slope
(0,2) and (10,14)
m=(y2-y1)/(x2-x1)
m=(14-2)/(10-0)
m=12/10
<em><u>m</u></em><em><u>=</u></em><em><u>6</u></em><em><u>/</u></em><em><u>5</u></em>
now take only one point from the graph to make a graph equation
(0,2) let us use this
m=(y2-y)/(x2-x)
m=(2-y)/(0-x)
m=(2-y)/(-x)
6/5=(2-y)/(-x)........... m=6/5
-x6/5=2-y
(-x6/5)-2=-y
-(-x6/5)(-2)=-(-y).....multiplying both sides by negative to make y positive
<em><u>Y</u></em><em><u>=</u></em><em><u>x6</u></em><em><u>/</u></em><em><u>5</u></em><em><u>-2</u></em>
The answer is 20
20+40=60
3(20)=60
