Answer:
y = 2x - 4
Step-by-step explanation:
Given point (1, -2) so x = 1, y = -2
Just plug in and verify
<u>y = x + 5 </u>
<u>y = 2x + 1 </u>
<u>y = 2x - 4 </u>
<u>y = x -2</u>
Answer:
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
solve for P
The answer for your question is a). Because if you add 12.6 pounds by 16.7 pounds you will get 29.3 as your answer.the estimated answer is 30 and,22.1 estimated is 22.Finally,you just subtract 30 by 22 and you get your answer as 8.
Answer:
DC = 3
Step-by-step explanation:
Based on triangle similarity theorem, we would have the following equation:
![\frac{AD}{AC} = \frac{AE}{AB}](https://tex.z-dn.net/?f=%20%5Cfrac%7BAD%7D%7BAC%7D%20%3D%20%5Cfrac%7BAE%7D%7BAB%7D%20)
Plug in the values
![\frac{9}{9 + DC} = \frac{12}{12 + 4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%7D%7B9%20%2B%20DC%7D%20%3D%20%5Cfrac%7B12%7D%7B12%20%2B%204%7D%20)
![\frac{9}{9 + DC} = \frac{12}{16}](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%7D%7B9%20%2B%20DC%7D%20%3D%20%5Cfrac%7B12%7D%7B16%7D%20)
![\frac{9}{9 + DC} = \frac{3}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%7D%7B9%20%2B%20DC%7D%20%3D%20%5Cfrac%7B3%7D%7B4%7D%20)
Cross multiply
3(9 + DC) = 9×4
27 + 3DC = 36
Subtract 27 from each side
3DC = 36 - 27
3DC = 9
Divide both sides by 3
DC = 9/3
DC = 3
Hi BellaMath1717,
Your Question:
Bob spent $37.80, including tax, on a pair of jeans. How much did the jeans cost if there was 8% sales tax?
Solution:
Step 1: Find The Tax
8% = 0.08
37.8 x 0.08 = 3.024
Tax = $3.024
Step 2: Find The Total
37.80 + 3.024 = $40.824 = $40.82
Final Answer:
$40.82
