She needs to answer 16 questions to get -80. (80÷5=16) but since she needs a smaller score than that to win the game, she then will have to answer more than 16 questions correctly. at least 17 to get less that -80. Hopefully I am understanding the question right.

Answer:

a. Function 1

b. Function 3

c. Function 2, Function 3 and Function 4

Step-by-step explanation:

✔️Function 1:

y-intercept = -3 (the point where the line cuts across the y-axis)

Slope, using the two points (0, -3) and (1, 2):

\frac{y_2 - y_1}{x_2 -x_1} = \frac{2 -(-3)}{1 - 0} = \frac{5}{1} = 5

Slope = 5

✔️Function 2:

y-intercept = -1 (the value of y when x = 0)

Slope, using the two points (0, -1) and (1, -4):

\frac{y_2 - y_1}{x_2 -x_1} = \frac{-4 -(-1)}{1 - 0} = \frac{-3}{1} = -3

Slope = -3

✔️Function 3: y = 2x + 5

y-intercept (b) = 5

Slope (m) = 2

✔️Function 4:

y-intercept = 2

Slope = -1

Thus, the following conclusions can be made:

a. The function's graph that is steepest is the function whose absolute value of its slope is greater. Therefore Function 1 is the steepest with slope of 5

b. Function 3 has a y-intercept of 5, which is the farthest from 0.

c. Function 2, Function 3, and Function 4 all have y-intercept that is greater than -2.

-1, 5, and 2 are all greater than -2.

Jenna earns $8.75 per hour working at the mall. If Jenna worked hours 20 1/5 last week, how much did she earn before taxes were
Elena-2011 [213]
To find out the amount Jenna earns, you need to multiply how much she earns per hour by the amount of hours she works for.

If she earns $8.75 for 1 hour, and works for 20 1/5 hours, she'll earn:
8.75 x 20 1/5 = 176.75

Jenna earns $176.75 before tax.
