Answer:

The rate of change is: as x increases by 10, y increases by 30. In other words, the rate of change is +30

Step-by-step explanation:

When calculating rate of change you see how much the y increases/decreases each time the x increases/decreases as we see, each time the x goes up by 10 the y goes up by 30.

According to the properties of inequality, when should the inequality symbol be reversed when solving a two-step any quality in
Marina86 [1]

According to the properties of inequality, we reverse the inequality symbol when we add or multiply by any negative number

Given inequality is Ax + B > C

In the first step, we subtract B from both sides

Ax + B > C

Ax + B - B > C - B

Ax > C - B

Now to remove A we divide by A on both sides

If A is negative then the reverse the inequality sign

When A is negative then > symbol becomes < symbol

so the inequality symbol be reversed when the value of A is negative

Tomtit [17]

Answer:

-170= -10m - 20

Step-by-step explanation:

-20 is the y intercept, so in the equation y=mx+b that would be the b. Because he is going down at 10 meters per minute, it means that the -10 would go into the x spot and the -170 is where he needs to get to. Hope this helped!
