These are linear equations, so there is x and y. On number one the first thing they plotted was (3,8) so in a function table the 3 would be on the left side and the 8 would be on the right side. I’ll leave you with the rule of the first one, if the rule is times 2 plus to the how would you put it in a function table.

The first thing that you would put into the function table on the first question would be as I said earlier 3 and then 8. The rule is the rate. Using a function table will be very helpful (That’s why I keep mentioning one). Let me know if this helps.

Answers

Answer:

it would be A

Step-by-step explanation:

the "<" (less sign) would mean B is less than A which is less than D which is less than C. if it is asking to put in the order which is greater than, there would need to be a ">" (greater sign). since there are no greater than signs, the process is flipped to be D is less than C which is less than A which is less than B meaning B is the greatest increasing likelihood, hope this helps :)

Answer:

(A) because it is more likely to draw a red or black card from a deck. Since the is letter d all the other choices don't have that so A is most likely the answer.

A cell phone battery with 22% charge takes 176 minutes to run out. How long will a fully charge battery last?

Answers

Answer:

800

Step-by-step explanation:

176 divided by 22=8

8x100= 800

It will take 13.33 hours to battery run out.

What is unit rate?

A unit rate means a rate for one of something.

Given that, A cell phone battery with 22% charge takes 176 minutes to run out.

In 22% → 176 minutes

In 1% → 176/22 = 8 minutes

In 100% → 8x100 = 800 minutes

800 minutes = 800/60 = 13.33 hours.

Hence, the battery will work for 13.33 hours when charged 100%
