how do i Subtract and simplify: (11x2 + 7) – (6x2 + 3x – 3)
7x+y
7x-y
X(7y)
Xy/7
Answer:X(7y)
Step-by-step explanation:
Answer:
It's C, I got a 100% on my quiz when I put C
Set up a proportion:
In a sample of 5:2, you have 7 kids in all.
So the the ratio of boys to kids in a sample of 7 is 2:7.
So set up a proportion:
=
7x =70
X = 10
Therefore, 10 of the boys went walking.
When you look at the graph, the X is the x value and the one on the f(x) is the y value, imagian it is on a graph and x is the steps you have to walk then imagain a ladder you have to go as high as the f(x) value says, then mark them. if they follow a pattern then write it down, if it does not then write incosentant.
Have a nice day.
