Answer:
One solution
Step-by-step explanation:
3x - 5 = - 3
1. Add 5 to both sides
3x= 2
Then Divide by three to get x alone
x= 2/3
X has only one solution here
Y = -2x^2 + 50x + 300
-2x^2 + 50x + 300 ≥ 300
-2x^2 + 50x ≥ 0
-2x^2 ≥ -50x
x^2 ≤ 25x
x ≤ 25
Therefore, required domain is 0 ≤ x ≤ 25
30, you can devide 135 by 4.5
Answer:
x = -2
Step-by-step explanation:
Equate x+2 with 0
x+2 = 0
x = -2

Answer:
34 hours
Step-by-step explanation:
Given that,
Nathan read a total of 630 pages over 30 hours.
We need to find times of reading will Nathan have to do this week in order to have read a total of 714 pages.
1 page can be read in 
To read 714 pages, it will take

Hence, it will take 34 hours to read 714 pages.
