6. A computer store charges $45 for materials and $50 an hour for service to install two new programs and a connection. The cost C(h) is a function of the number of hours h it takes
to do the job. Graph the function C(h) = 45 + 50h.
a) How much will a 3-hour installation cost?
b) Find h when C(h) = 395. Explain what the answer means.
c) Find C(5) Explain what the answer means

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

u bout ugly as   a mf

step-by-step explanation: lol

i’m here for points.
