Answer:x^2 +15x +36
Step-by-step explanation:
Answer:
The function with the largest value will be
Step-by-step explanation:
we know that
As x increases beyond 25 , that means
x> 25
so
Assume x=30
Substitute the value of x in each equation and find the value of the function, and then compare the results
case 1)
For x=30
case 2)
For x=30
case 3)
For x=30
case 4)
For x=30
therefore
The function with the largest value will be
Answer:11
Step-by-step explanation:y negative is not the common squared but x is so you do math x=yx5=11
Answer:
x/3.5h = -$1.4
So, x = -$1.4 * 3.5h
= -$4.9
Step-by-step explanation:
Since your losing $1.4 every hour, the 1.4 is supposed to negative.
Also, since your losing that amount of money for 3.5 hours, we are trying to find the total of how much money is lost in the 3.5 hours. To do this, we have to do x/3.5h = -$1.4. But since you can't do x/3.5, we have to do inverse operation. When you divide 3.5 hours to the other side of the equation it becomes multiplication. So you do -$1.4 times 3.5 hours
and get -$4.9.
