Answer:

C

Step-by-step explanation:

Since z = 7 the equation would be 3(7) - 3

You would multiply 3 with 7 and get 21

Then you would subtract 3 from 21 and get 18

hope this helps.

The graph below shows the distance, y, in miles, of a bird from its nest for a certain amount of time, x, in minutes: Graph titl
Degger [83]

<u><em>Answer:</em></u>

The initial value is 3

It represents the distance between the bird and its nest before any elapsed time which is 3 miles.

<u><em>Step-by-step explanation:</em></u>

The graph is shown in the attached image.

<u>The general form of a straight line is:</u>

y = mx + c

where:

m is the slope and c is the y-intercept.

The y-intercept is also known as the initial value. It is the value of y at x=0.

From the givens, we can note that at x = 0, the y-value is 3. This means that the y-intercept is 3.

Now, in the problem, x represents the time in minutes while y represents the distance of the bird from the nest in miles.

At x = 0, meaning before any time elapsed, the distance of the bird from its nest was 3 miles.

Hope this helps :)

What value of x makes this equation true?<br> 0.5x – 8= 0.2x + 7
postnew [5]
The value of x that will make this equation true is 50.

0.5 times 50=25 -8 = 17

0.2 times 50= 10 +7 = 17

Therefore, your answer is 50.
