Answer:
Step-by-step explanation:
That is a description of the formula for the rectangle rule using left endpoints.
Formula for slope: y2-y1/x2-x1
Plug in values.
3-8/-4-(-7)= -5/3 = slope
42-1/36-12=41/24=slope
1/3(21 - 3a) = 6 - a
7 - a = 6 - a
7 = 6
Therefore, the equation has no solution.
Answer:
Any number from 1-5
Step-by-step explanation:
Less than 6!
