Answer:

18 hours

Step-by-step explanation:

There are 24 hours in a day and we have 5 weekdays per week.

15% of 24 hours

15/100×24

0.15×24

=3.6 hours

Mrs Miller spends 3.6 hours of each weekday traveling in her car.

There are 5 weekdays in a week to include: Monday, Tuesday, Wednesday, Thursday and Friday.

If she spends 3.6 hours per weekday

Then,

During the week, she will spend

3.6 hours× 5 weekdays

=18 hours

She will spend 18 hours per week traveling in her car.

Write the equation of the line that passes through the given points.<br> (0, -1) and (-5.-9)
Elis [28]

Answer:

y=\frac{8}{5}x-1

Step-by-step explanation:

<u>Recall:</u>

  • Slope -> m=\frac{Rise}{Run}=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}
  • Slope-intercept form -> y=mx+b
  • Y-intercept -> b

<u>Given:</u>

  • (x_1,y_1) = (0,-1)
  • (x_2,y_2) = (-5,-9)

<u>Slope calculation:</u>

Slope=\frac{y_2-y_1}{x_2-x_1}=\frac{-9-(-1)}{-5-0}=\frac{-9+1}{-5}=-\frac{8}{5}=\frac{8}{5}

<u>Y-intercept calculation:</u>

y=\frac{8}{5}x+b

-1=\frac{8}{5}(0)+b

-1=0+b

-1=b

<u>Final equation:</u>

<u />y=\frac{8}{5}x-1<u />
