The ordered pair (3,2) is a solution.
To graph the function: first plot the y-intercept at -4. Next from the y-intercept, count up 2 units and then right one unit and plot a point, continue to do this until you have several points plotted (at least 4). Next using a straight-edge, draw a line through the points.

Can you answer these 3 questions for me plz
finlep [7]
A.
1hr \: 15min = 75min

c = 0.22t = 0.22 \times 75 = 16.5

cost is $16.50

B.

26.40 = 0.22 \times t

rearrange to solve for t:

t = \frac{26.40}{0.22} = 120min

C. This is the same as part B, only the rate changed

t = \frac{26.40}{0.25} = 105.6min

they ask for the greatest number of minutes, so we round down (take the floor of the value).

the answer is 105 minutes.

egoroff_w [7]

Multiply 80 by 14 to get how many total people they can feed.

80 times 14 is 1120.

Now, divide 1120 by 32 to get how many days the food will last if 32 people come every day.

1120/32 = 35.

The answer is B, 35 days
