Answer:
y=-5x + 19
Step-by-step explanation:
Slope-intercept form: y=mx+b
Plug in the point.
9=-5(2)+b
Simplify.
9=-10+b
Solve for b.
b = 19
Mark as brainliest if this helps :D
Answer:
Substituton is like being a back up to anything and for anuone
Answer:
Length = 5
Width = 21
Step-by-step explanation:
(x)(x + 16) = 105
x^2 + 16x = 105
x^2 + 16x - 105 = 0
(x - 5) x ( x + 21) = 0
x - 10 = 0
x = 5
x + 21 = 0
x = -21
Now that we have the zeroes.
We have to find the most viable one to put in.
Using -21 would not make sense, so we will use 5.
Plug it in:
x = 5
(5) (5 + 16) = 105
5 ( 21) = 105
The answer would be
C = 10
P = 20
