How do you simplify the like terms in 9y-y-7y+3

9y-y-7y+3= y+3

Step-by-step explanation:

Any time there is no number in front of a variable, it's automatically 1, you just don't put the 1 there. So it would be

9y - 1y= 8y

So after you do that, you take the 7y and subtract it from 8y

8y - 7y= 1y

And remember you don't put the 1 so it simplifies to just y.

You simply add or subtract all the numbers with the same variable

I'm not the best at explaining so if you have any questions on it I can answer them in the comments :)

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
