colleen's family plans to paint the windows of their house. her father will paint twice as many windows as her mother, and Colle
Morgarella [4.7K]

Answer: 24

Step-by-step explanation:

Colleen painted 7 windows, some of which were her mother's.

Her dad painted 7+1 (8) windows, and that is twice as much as what her mother was supposed to do. Her mother was supposed to do 4 windows. That means Colleen's share was 3 windows.

If all the kids had to do an equal amount of windows, than each kid had to do 3 windows.

8+7+3+3+3=24

I need to finish these so I don't fail, help me out
Dima020 [189]

Answer:

y < -2x - 4

Step-by-step explanation:

This is a guessing game. You just have to plug and chugg to find your answer.

Look at the table they gave you and plug in the x and y value into the given equations and see if they're true or not.

For example, I used the point x=-2 and y=1 from the table.

I plug that into y < -2x - 4 and got a false statement:

y < -2x - 4

(1) < -2(-2) - 4

1 < 4 - 4

1 < 0

this is false because one cannot be less than zero. Therefore this equation is the wrong one.

If you tried to plug in x=-2 and y=1 into the other 3 equations you'll see that they'll be correct.
