Answer:

y = -x/4 -2

Step-by-step explanation:

Linear function is in the form;

y = mx + b

The first point is (4,-3)

so we have;

-3 = 4x + b

The second point is (0,-2)

Thus;

-2 = 0(x) + b

b = -2

Put this in the equation above

-3 = 4x -2

-3 + 2 = 4x

4x = -1

x = -1/4

So the equation is;

y = -x/4 -2

The amount of time is takes dora to commute to work is always within 5 minutes of the average number of minutes the commute take

Maslowich

Answer:

The average time to commute to work is 25 minutes.

Step-by-step explanation:

If average time for Dora to commute to work is 5 mins. If she takes 45 mins to get to work then her overall average time to commute to work will change as the average consists of 2 or more figures. The average time to commute to work is 25 mins ((5+45)/2). The average of 5 mins and 45 mins is 25 mins. This is the overall average time she takes to commute to her work.

Monique made several batches of soup for a potluck supper. Each batch required 3/4 of a pound of potatoes, and she used a total

elena55 [62]

If Monique used a total of 6 1/2 pounds of potatoes and each batch required 3/4 of a pound of potatoes, then you have to divide the total amount of pounds by an amount of pounds needed for one batch:

$6\dfrac{1}{2}:\dfrac{3}{4}=\dfrac{13}{2}\cdot \dfrac{4}{3} =\dfrac{26}{3}=8\dfrac{2}{3}.$
