Leno4ka [110]

Answer:

16/4

Step-by-step explanation:

<u>Step 1:  Convert to improper fractions</u>

2 2/4 = 2 * 4/4 + 2/4 = 8/4 + 2/4 = 10/4

1 1/2 = 1 * 2/2 + 1/2 = 2/2 + 1/2 = 3/2

<u>Step 2:  Make common denominator</u>

10/4 is ok

3/2 * 2/2 = 6/4

<u>Step 3:  Combine </u>

10/4 + 6/4

16/4

Answer: 16/4

I would really appreciate help
alexira [117]
Check your y-intercept on the graph, it is at 3. Now go up two units and then move three units to the right you will see that it lands on a point. This is called rise/run. The shading goes above the line so that means you will use this symbol: >. Also it is a dotted line. So your inequality would be:
y > 2/3x + 3
I hope this helps love! :)
