Alright!

As usual, x is equal to our time value, which in this case is the number of consecutive days the player he has practised for two hours. Now, they do give a large hint here for the question.

How many days can this basketball Playin' fool make an average of 9 consecutive free throws?

Well...

They tell you!

Let's plug in 9 for the value of x, and solve this here function -

f(9) = 1 + 1.5 (9 + 1).

f(9) = 1 + 1.5 * 10.

f(9) = 1 + 15.

f(9) = 16

It will take 16 days of practise!

-3x+4=13 SOLVE PLZ! INEQUALITY
arlik [135]
Hi!

What you'll first need to do is subtract 4 from 4 and 13. After doing so, your equation will look like this...

-3x=9

Next, you'll need to divide -3x and 9 by -3. After you've done that, you'll get...

x=-3.

So your answer would be x=-3

I hope this helps!
