Can somebody explain this in a basic way and help me graph it??!!
7nadin3 [17]

Hello!

To graph this, you will want to create two points based off of the equation. You plug an x-value into the equation, and you put the y-value outcome with it as an ordered pair. You do this twice, giving you two points to connect.

For example, let's plug in an x-value 1, giving us (1,y)

y= 1-3 (We remove the absolute value)

y=-2 (Subtract)

This gives us one point, (1,-2)

Let's try using -2 as another point.

y= 2-3 (Remove absolute value)

y= -1 (Subtract)

This gives us the point (-2,-1)

To graph, you would draw a straight line through the points (1,-2) and (-2,-1). Note you could do this with any x-value and you would get the same line.

I hope this helps!

Jamar has a points card for a movie theater.
netineya [11]

Answer:

He needs to make at least 6 visits.

Step-by-step explanation:

The signing up amount, 20, is a fixed amount.

The amount he receives per movie is 12.5 times the number of visits, v, or 12.5v.

The total amount of points he earns is the sum of the fixed amount and the amount due to the number of visits.

earned points = 12.5v + 20

He must earn 95 points or more.

12.5v + 20 ≥ 95

Subtract 20 from both sides.

12.5v ≥ 75

Divide both sides by 12.5

v ≥ 6

He needs to make at least 6 visits.
