The nearest tenth would be 40
That is easy use photo math your welcome
4)C
5)A
6)D
7)-4/3x-1(use formula y=mx+b, m is slope, x and y is the x and y of the one point that is given, b is y-intercept)
8)B
***Slope is the number multiplied with the x and y-intercept is the last number. It's obvious
I'm not sure how many equations you are asking for, but hopefully, you can use what I wrote here to solve your actual question. Here is my go:
3x+10+2x+2+5x
First, add all the x's together:
3x+2x+5x=10x
Next, add all our numerals together:
10+2=12
Put it together!
10x+12
C 136 is the correct answer
