The answer for question four is B.80
Answer:
The answer is C
Step-by-step explanation:
117 + 23 =140 and you have $140 in all so you spent it all
Answer:
-5+(√x-3) and -(√x-3)-5
Step-by-step explanation:
change f(x) to 'y' and then interchange x and y; then solve for y
y = x² + 10x + 28
x = y² + 10y + 28
you can use the Quadratic Formula to evaluate y² + 10y + 28 and will get:
-5+(√x-3) and -(√x-3)-5
Answer:
$8.5
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>Dave also starts a new job, but his hourly pay starts at $7.25. Suppose that he gets a 40¢-per-hour raise each year.
What will Vicky’s hourly pay be in 3 years</em>
My answer:
Given:
- Rate per hour: $7.25.
- Hour raise each year: 40¢-
=> the percentage of rate increasing:
(40¢ / $7.25)*100%
= (40¢ / 7.25*100¢)*100%
= 5.5%
What will Vicky’s hourly pay be in 3 years
This is a compound growth problem. The formula is:

<=> F = 
<=> F = $8.5
So the rate after three years is $8.5
Hope it will find you well.
