Answer: It already tells you what DE= 60
Step-by-step explanation:
Since F is the midpoint of DE that means DF=FE
So create equation
When DF and FE is added your answer should equal DE
So you write the equation to find x and once x is found substitute your answer for x
subtract 12 on both sides 36-12= 24
subtract 2x on both sides 4x-2x=2x
divide 2 into both sides 24/2=12 x=12
4x12=48+12=60 2x12=24+36=60
2.)
0 = 6x + 3y +9
-3y = 6x + 3y - 3y +9
By isolating y we now have the equation in slope intercept form:
Where m = slope and b = y- intercept. Therefore, the slope is -2 and the y - intercept is -3.

Similarly, #4 is already in slope intercept form so we can solve it by inspection. So for #4 the slope is -1 and the y - intercept is 2.
0 = 6x + 3y +9
-3y = 6x + 3y - 3y +9
By isolating y we now have the equation in slope intercept form:
Where m = slope and b = y- intercept. Therefore, the slope is -2 and the y - intercept is -3.
