when Larissa's watch is fully charged, it can last for up to 20 hours before running out of battery. It has been 12 hours since Larissa's watch was fully charged. Write an inequality to describe the situation, then complete the sentence

x + 12 ≤ 20 x=8

Step-by-step explanation:

Since Larissa is able to use it up for 20 hours and she has been using it for 12 hours now so add 12 with 12 and 20 with 12 then subtract the sum from the added numbers and you will get 8

So Larissa has 8 hours left on her watch before it needs to charge

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
