3 hours would be $27.30
You take $45.50 and divide it by 5 to get the charge of one hour then times it by three.
You can also do $72.80 divided by 8 to get the charge of one hour, then times it by 3.

Write an equation for a line that is parallel to y=-8x+5 and contains the points (1,-2).
Lina20 [59]

Answer:

y = - 8x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 8x + 5 ← is in slope- intercept form

with slope m = - 8

Parallel lines have equal slopes, thus

y = - 8x + c ← is the partial equation of the parallel line

To find c substitute (1, - 2) into the partial equation

- 2 = - 8 + c ⇒ c = - 2 + 8 = 6

y = - 8x + 6 ← equation of parallel line

What is the general form of the equation of the line shown? x - 2y - 3 = 0 2x - y + 3 = 0 2x - y - 3 = 0
choli [55]
The general form of the equation for a straight line is
y = mx + b
where 
m = slope
b = y-intercept.

Consider the equation x - 2y - 3 = 0.
Add 2y to each side.
x - 3 = 2y, or
2y = x - 3
Divide through by 2.
y = (1/2)x - 3/2
This is in general form.

Consider the equation 2x - y + 3 = 0.
Add y to each side.
2x + 3 = y, or
y = 2x + 3
This is in general form.

Consider the equation 2x - y - 3 = 0.
Add y to each side.
2x - 3 = y, or
y = 2x - 3
This is in general form.
