Answer:
x = 15p
-75
Explanation:
remove brackets:
4px + 4 = 64
solving for x --> 4px = 64 - 4 then--> 4px = 60
then diving both sides by 4p --> x = 60\4p --> x = 15p
now solving for x when p is -5
we will substitute the -5 in the equation we got --> x= 15 (-5)
which will give us --> x = -75
1) Parallel lines have the same slope, so the answer is 1/2
2) Perpendicular lines have slopes that are negative reciprocals, so the answer is -2
3) The equation of the perpendicular is y = -2x - 6, so a point is (0, -6)
Plug in the x+3 for y.
8x-x+3=12
7x=9
X=1.3
Then, y= -0.25
The answer is -7
2x-3(x+4)=-5
Multiply by -3
2x-3x-12=-5
Collect like terms
-x-12=-5
Move constant to the right to change its sign
-x=-5+12
Add
-x=7
Change the signs
x=-7
That would be the area of a circle of radius 12 miles
= pi r^2 = 452.4 square miles to nearest tenth.
