Answer:
3 points
Step-by-step explanation:
in a function, an x-value must have only one y-value correlated with it.
So, you would need to remove either (-3, 2) or (-3, 3)
And, you would need to remove either (2, -2) or (2, -4)
<em>And, </em>you would need to remove either (1, 4) or (1, -4)
So--you need to remove 3 points in total for this to be a function.
[a y-value can have multiple x-values. the two points at -4 are allowed, and do not need to be removed for both of them to be there]
Consecutive even integers are 2 apart
they are
x,x+2,x+4
total sum is 60
x+x+2+x+4=60
3x+6=60
minus 6 both sides
3x=54
divide both sides by 3
x=18
x+2=20
x+4=22
the ages are
18,20,22
Answer:

Step-by-step explanation:
Let the number of cups of onions Katrina still needs to chop = x
She has already chopped the onions =
cups ≈
cups
So total amount of chopped onions =
cups
Since, onion soup recipe calls for the chopped onions =
cups ≈
cups
Therefore, equation which shows the number of cups of onions to be chopped more will be,

We further solve this equation for the value of x,
x = 
x = 
=
cups
≈
cups
