The answer is D. I wasn't sure if the 2 after a t was a square. if so it looks like this
Here you go, hope this helps. Don’t mind the water droplets, accidentally topped my bottle over.
Answer:
P = 500 - 40t
Step-by-step explanation:
P is the number of pages has left to read
the initial value is 500
the rate of change is 40 pages per hour (t)
you must subtract from the initial
The equation is P = initial - 40t or
P = 500 - 40t
To check, at 0 hours you have 500 pages or P = 500 - 40(0)
at 10 hours, P = 500 - 40(10) = 500 - 400 = 100
Stokked 120
how many left?
300-120=180
180/300=x%
percent means parts out of 100
180/300=60/100=60%
60% left
B) 2x + 3y < 5 and -3x +2y < 6
