Answer:
a10 = 25
Step-by-step explanation:
I'm not certain that I have interpreted the question in the way it was intended; however, if I have:
a
10 = 3
(10
) − 5 =
30 − 5 = 25
<h2>We know:</h2>
You currently make $13.50 an hour. You've earned a 15% pay raise. You want to find out your previous rate of pay per hour.
<h2>Steps:</h2>
1.) Convert 15% to a decimal, which equals 0.15
2.) Multiply your current earnings with the percentage in decimal form (0.15)
$13.50 (current pay per hour) x 0.15 (percentage in decimal form) = $2.025 (difference between your previous wage and your current wage)
3.) Subtract the difference of your previous wage and current wage with your current earnings
$13.50 (current pay per hour) - $2.025 (difference between previous and current wage) = $11.475 (previous pay per hour)
4.) Since this is talking about wage, rounding is not applicable. In other cases, your number would be rounded off to $11.48, however you can't add what you don't have, so you would have to round down.
<h2>
You were previously making $11.47 an hour.</h2>
Round to the nearest ten. Look at the ones value, it is a 0. Because 0 is less than 5, round down
913610 rounded to the nearest ten is 913610
hope this helps
Answer:
<u><em>Part A:</em></u> D. 
<u><em>Part B:</em></u> C. 
Step-by-step explanation:
For part A) we just have to plug in 0 for x and solve for y until we find the equation that says 3 is the value for y when x is 0. For purposes of speeding up the process the correct answer is D. I will show how to check for it now.
The equation: 
Now plug in 0 for x.

Now solve.
y = (1)(3)
y = 3
This proves that this is the correct answer.
For part B) we just have to plug in the give values for x separately and check for each value of x that it equals 0. For the purpose of speeding up the process the correct answer is C. I will show how to check for it now.
The equation: 
Now plug in x for 0 and solve:



This equation is true, now we check for the other value of x, 3.



This is also true so that means this is the correct answer.
