Answer:

Alternatively you can write it as;

Step-by-step explanation:
One time service fee=$99
Rate of service=$50/hour
let unknown hours=x
Therefore the equation is

or you can further simplify it to:

And you can then solve for x to be 9 hours.
Question 1.
First solve for slope:

Point-slope formula is:

where m = slope.
Plug in values for PS form:

So the answer is Choice 2.
Question 2.
Choice D.
Points given: (-10, -7) and (3, -7)
Both y -intercepts are equivalent to -7
Question 3.
Choice A.
Points given: (2, 4) and (2, -7)
Both x - intercepts are equivalent to 2
Answer:
1.668 S
Step-by-step explanation:
We are given that
Product
For first order reaction,


Rate constant=k=
Temperature=
We have to find the time taken by the reaction when concentration of A to decrease from 0.790 M to 0.230 M.


Substitute the values then we get


Hence, it would take 1.668 s for the concentration of A to decrease from 0.790 M to 0.230 M.
The answer is .66666666 however on a calculator it will show .66666667 as a way to round all you have to do is divide 2 and 3
