1st...
80 * 115
P = 2 * 80 + 2 * 115
P = 160 + 230
P = 390 is the perimeter
A = 80 * 115
A = 9, 200 is the area.
I could only get the first part done for you maybe others are watching where they can help you with the second part of the question:::
Hope that helps!!!!
Answer:
it is linear and it does have a constant rate of change
Step-by-step explanation:
Answer:
-5
Step-by-step explanation:
The initial value would be the value when x=0. Substituting 0 for x,
y = -2(0)-5
y = 0 - 5
y = -5
Answer:
(2, 18) or x = 2 and y = 18
Step-by-step explanation:
From substitution:
9x = 3x + 12
6x = 12
x = 2
y = 9x = 9 * 2 = 18
