Perpendicular line has slope that multiplies to -1
paralel line has same slope
y=mx+b
slope=-7/4
perpendicular
4/7
(-7,-2)
-2=4/7(-7)+b
-2=-4+b
add 4 both sides
2=b
y=4/7x+2
paralel
y=-7/4x+b
-2=-7/4(-7)+b
-2=49/4+b
minus 49/4 from both sides (-2=-8/4)
-57/4=b
y=-7/4x-14.25
perpendicular
y=4/7x+2
paralel
y=-7/4x-14.25
-3x-5+2x=6
2x-3x-5=6
-1x-5=6
-x-5=6
-x=11
x=11
an equivilent equaiton is x=11
Answer:
Delta does not have a relative extreme in the equation, so it is variable y It can not be true
Step-by-step explanation:

There is an answer
The rest of the equation that has no substituted delta is not true, so the prime variables have relative extremes.
Area = 299*34 = 10166 ft^2
Cost = 10166 * 11 = $111,826 (answer)
Answer:

Step-by-step explanation:
We have

and

We want to find (f+g)(x).
By the algebraic properties of polynomial functions,


This simplifies to

We can't simplify further, hence the simplest form
