Answer:

  5 hours

Step-by-step explanation:

A quick way to look at this is to compare the difference in hourly charge to the difference in 0-hour charge.

The first day, the charge is $3 more than $12 per hour.

The second day, the charge is $12 less than $15 per hour.

The difference in 0-hour charges is 3 -(-12) = 15. The difference in per-hour charges is 15 -12 = 3. The ratio of these is ...

  $15/($3/h) = 5 h

The charges are the same after 5 hours.

__

If you write equations for the charges, they will look like ...

  y1 = 15 + 12(x -1)

  y2 = 3 + 15(x -1)

Equating these charges, we have ...

  15 +12(x -1) = 3 + 15(x -1)

  12x +3 = 15x -12 . . . . . . . . eliminate parentheses

  15 = 3x . . . . . . . . . . add 12-12x

  x = 15/3 = 5 . . . . . . divide by 3

You might notice that the math here is very similar to that described in words, above.

The charges are the same after 5 hours.

Refer to the triangle below what is the volume of X. 45° 60°
RUDIKE [14]

Answer:

x = 75

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180 for x

x = 180° - (60 + 45)° = 180 - 105° = 75°

What would be the slope for (-4,-7) (-6,4)​
Sliva [168]

Answer:\frac{11}{-2}

Step-by-step explanation:

ok so I'm going to try to show it the best c an

m = slope

the equation you use is

\frac{y2-y1}{x2-x1} = m

so when using that formula with the cords, you get

\frac{4-(-7)}{-6-(-4)}

and then subtract everything and you'll get

\frac{11}{-2}
