Answer:
Jorge was charged for 10 hours that month
Step-by-step explanation:
Given : Jorge’s monthly bill from his Internet service provider was $25.
Also given : The service provider charges a base rate of $15 per month plus $1 for each hour that the service is used
We have to find the number of hours that Jorge was charged for that month.
Let the number of hour be x,
Total bill = base rate + 1 (number of hours used)
Total bill = base rate + 1(x)
Substitute the values, we get,
⇒ 25 = 15 + 1 (x)
Solving we get,
⇒ 25 - 15 = x
10 = x
Thus, Jorge was charged for 10 hours that month
Answer:
A) (-5, -34)
Step-by-step explanation:
f(x) = x^2 + 10x - 9
We complete the square to get the equation in vertex form
Take the coefficient of the x term and divide by 2 then square it. We add it and then subtract it not to change the value of the equation
f(x) = x^2 + 10x +(10/2)^2 - (10/2)^2 - 9
f(x) = x^2 +10x +25 -25 -9
f(x) = (x^2 +10x +25) -34
The term in parentheses simplified to (x+10/2) ^2
= (x+5)^2 -34
= (x - -5)^2 -34
This is in the form (x-h)^2 +k
The vertex is (h,k) h=-5 and k=-34
(-5,-34)
Answer:
4! = 4 x 3 x 2 x 1
4! = 12 x 2 x 1
4! = 24 x 1
4! = 24
