10b - b + 1 I the question Im Stuck on . Please help !!

9b + 1

Step-by-step explanation:

Is it 9b + 1 because 10b and the variable b are like terms. There is an invisable 1 in front of the b. So you just do it like this, 10b - 1b + 1, which is 9b + 1. the 1 has no variable, so just leave it alone and that is your answer. I really hope I helped you out!

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
