Well I know that c. goes with I. just because I saw so many x^3 graphs.

For a. the parent function is x^2, so 0.5x^2 should look about the same as x^2, so the answer is VI.

War Eagle spied 1428 antelope and wildebeests grazing on the savannah. If the ratio of antelope to wildebeests was 9 to 5, how m
Nonamiya [84]

Answer:

9:5 = 1428:x

ratios can also be written as fractions, so

9/5 = 1428/x

solve for x

9/5 × x = 1428

x = 1428 / (9/5)

x = 918

This table shows the input and output values for a linear function f(x).
Svetlanka [38]

Answer:

-25

Step-by-step explanation:

The following are x-values (inputs) and their y-values (outputs) that are one value apart:

(Input, output)

✅(-2, 20) and (-1, -5)

Difference between their outputs = -5 - 20 = -25

✅(-1, -5) and (0, -30)

Difference between their outputs = -30 -(-5) = -25

✅(0, -30) and (1, -55)

Difference between their outputs = -55 -(-30) = -25

✅(1, -55) and (2, -80)

Difference between their outputs = -80 -(-55) = -25

As we can see the difference of outputs for any two inputs that are one value apart = -25

The graph below represents an employee's earnings based on units sold. What can be interpreted from the slope of this graph?
Vesna [10]

Answer:

A

Step-by-step explanation:

<u />

From inspection of the graph, we can see that every time the x-value increases by 10, the y-value increases by 1000.

So, the employee earns an additional $1000 for every 10 units sold.

To calculate how much the employee earns for every 1 unit sold, divide $1000 by 10:

1000 ÷ 10 = 100

Therefore, the employee earns an additional $100 for every one unit sold.

<u />

<u>Proof</u>

This can be proved by calculating the slope (gradient) of the graph:

\sf slope=\dfrac{y_2-y_1}{x_2-x_1}

where \sf (x_1,y_1) and \sf (x_2,y_2) are two points on the line

When picking the two points, remember that the <u>y-values are in </u><u><em>thousands</em></u><u> </u><u>of dollars.</u>

<u />

Two points on the line:

(0, 30000) and (20, 32000)

Substituting these into the formula:

\sf \implies slope=\dfrac{32000-30000}{20-0}=\dfrac{2000}{20}=100

Therefore, the employee earns an additional $100 for every one unit sold.
