Answer:

<h2>The cost increases $3.99 for every additional movie rented.</h2>

Step-by-step explanation:

In this situation, the rate of change means the cost per movie.

Specifically, the cost is $3.99 per movie. In other words, the cost increases $3.99 when the number of movies increases by 1.

We could also say it like the cost increases $3.99 for every additional movie.

Therefore, among the options the second choice is correct, because specifies the right ratio of change that the table shows.

You can get this ratio of change by subtracting $7.98 - $3.99 = $3.99. Then, if you sum this difference to $7.98, you would get $11.97, and then $15.96, and so on. That means the ratio of change is $3.99 per movie.

Cost of 2 kg of pork is

$=2*7.99 = $15.98$

And cost of 3 kg of pork is

Solve each two-step inequality and graph the solution set on a number line -17 < 3-5x

lawyer [7]

Answer:

$x < 4$

Step-by-step explanation:

Given the following question:

$-17 < 3-5x$

In order to find the answer, we will solve the inequality as if it is a regular two-step equation and then we will plot the answer on the number line.

$-17 < 3-5x$
$-17 < 3-5x=3-5x > -17$
$3-5x > -17$
$3-3=0$
$-17--3=-20$
$5x=-20$
$\frac{5x}{5}=x$
$20\div5=-4$
$x < 4$

<u>When plotting inequalities on the number line keep a few things in mind:
</u>
. 4 is greater than x, so the line will go towards the opposite direction of four
. < is a greater sign, it's not a greater or equal to sign (≤) which means it will be an open dot.

Hope this helps.
