Step-by-step explanation:
Answer: she can rent the bike for a maximum of 13 hours.
Step-by-step explanation:
Let h represent the number of hours for which she rents the bike.
The equation used by Janis to find the total cost, C, in dollars, of renting a bike for h hours is expressed as
C = 4h + 8
If Janis does not spend more than $60, then it means that
4h + 8 ≤ 60
4h ≤ 60 - 8
4h ≤ 52
h ≤ 52/4
h ≤ 13
Therefore, the maximum number of hours for which she can rent the bike is 13.
The domain of f(x) = -6x^2 - 10x + 13 is all real values.
For the range f(x) = -6x^2 - 10x + 13 written in vertex form is -6(x^2 + 5/3x - 13/6) = -6(x^2 + 5/3x + 25/36 - 13/6 - 25/36) = -6(x + 5/6)^2 - 6(-103/36) = -6(x + 5/6)^2 + 103/6
Range is all real values less than or equal to 103/6
Answer:
The formula to calculate the final cost of Sally's new car:
C = 35000 x (1 + 4.5/100)^6 = 45579.1 dollar
Hope this helps!

Answer:
y= 1/2x + 17/2
Step-by-step explanation:
First, find your slope using y-y1/x-x1. This is your expression: 10-6/3--5. 10-6 equals 4, and 3--5 equals 8. Your slope is 4/8, but it can be simplified to 1/2. This should be your current equation: y=1/2x+b. Plug in one of your ordered pairs to the equation, it doesn't matter which pair you want to use. I'm using the second ordered pair, so this is what you would have: 10=1/2(3)+b. Multiply 1/2 by 3 to get 3/2. This is what it should look like: 10=3/2+b. Subtract 3/2 from both sides to get your y-intercept of 17/2. Go back to your original equation and plug in your y-intercept. This is your final answer: y= 1/2x + 17/2. Hope this helped!
