Answer:
y=-2x+2
Step-by-step explanation:
Given line is-
x-2y=7
we know,
equation of line perpendicular to ax+by=c is bx-ay=k
So, equation of line perpendicular to x-2y=7
is given by -2x-y=k
Now, the line -2x-y=k passes through (5,-8)
So, we get
-2(5)-(-8)=k
or, -10+8=k
or, -2=k
So, k=-2
Using the k value we get,
Equation of the line is-
-2x-y=-2
multiplying by -1
2x+y=2
or, y=-2x+2
This is the slope intercept form of the line.
The slope would be 0.11x + 99 because they charge 0.11$ per mile and a starting fee of $99
Answer:
The first one is F' each one is around $36
Answer: First step would be doing the () first. The third step would be 4 times 0. I think so, forgive me if I’m wrong.
Step-by-step explanation:
Answer:
The answer is 36xy^2 + 8x^2 + 27y^2 + 6x is your product polynomial.
Step-by-step explanation:
(-4x-3)(-2x-9 y^{2} )
-4x(-2x-9 y^{2} ) = 8 x^{2} +36 xy^{2}
-3(-2x-9 y^{2} ) = 6x + 27 y^{2}
