#1 is 65 by 75, next is 3 by 9, and the last is 75 by 25
Answer:
the standard is that a person can read 40 to 50 pages in an hour on average.
Step-by-step explanation:
52x2 is 104, and you need 130 pages it, i say that you cant complete the homework under two hours
10+5=15 so $100/15= 6.67hrs. She could work about 7hrs.
she could work 7 hrs if rounded to nearest tenth
The quadratic formula is:
and 
In this case, a = 2, b = -3, and c = -7
So, we can plug in the numbers to get:
and 
Simplifying, we get:
and 
You need to use a calculator to find what these would be in decimal form. The answer, rounded to the nearest tenth, is: x = 2.8, x = -1.3
To find f(-20), first figure out which piece x = -20 fits with.
Since -20 < -12, x = -20 first in the domain used by the third piece.
For f(-20), treat this function as if it was just f(x) = 3x-7.
f(-20) = 3(-20) -7
= -60 - 7
= -67
