$150 because the supply number is equivalent to the demand number
Step-by-step explanation:
y = 9x - 7
When x = 8
y = 9.8 - 7
y = 72 - 7
y = 65
When x = 6
y = 9.6 - 7
y = 54 - 7
y = 47
When x = 7
y = 9.7 - 7
y = 63 - 7
y = 56
When x = -8
y = 9.(-8) - 7
y = -72 - 7
y = -79
When x = 4
y = 9.4 - 7
y = 36 - 7
y = 29
The perimeter of a parallelgram is the sum of the lengths of its four sides.
Parallelogram ABCD has sides AB, BC, CD, and AB.
Sides AB and CD are parallel and of equal length = 19 units.
Sides BC and CD are parallel and of equal length. Assuming thi is the length of 5 units given in the statement, the perimeter of the parallelogram ABCD is: 19 units + 19 units + 5 units + 5 units = 48 units.
Please, inform if the length of 5 units corresponds to other distance, but even in that case, with this explanation you should be able to calculate the perimeter of this and other parallelograms.
Answer: 48 untis.
Part A : y=$0.75m+$4.50
Part B : $8.25
