Answer:
The correct answer is d.
Step-by-step explanation:
Let's solve each answer and see which one matches.
Note that in each case, you simply add or subtract from x inside the radical to move left or right respectively. Similarly, just add or subtract to the full expression to move up or down respectively. Doing so we get:
a) ![f(x) = \sqrt[3]{x + 7} + 3](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Csqrt%5B3%5D%7Bx%20%2B%207%7D%20%2B%203)
b)![f(x) = \sqrt[3]{x - 3} - 7](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Csqrt%5B3%5D%7Bx%20-%203%7D%20-%207)
c)![f(x) = \sqrt[3]{x - 3} + 7](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Csqrt%5B3%5D%7Bx%20-%203%7D%20%2B%207)
d)![f(x) = \sqrt[3]{x - 7} + 3](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Csqrt%5B3%5D%7Bx%20-%207%7D%20%2B%203)
So d is the correct answer.
Answer:
15 minutes
Step-by-step explanation:
distance = rate · time
16 = 20r
r = 16/20 or 4/5 miles per minute
12 = 4/5·t
4t = 12·5
t = 60/4 or 15 minutes
Answer:
Last week Alexander earned $792 in commissions.
Step-by-step explanation:
Giving the following information:
Commission= 11%
Sales= $7,200
T<u>o calculate the total commission, we need to use the following formula:</u>
Total commission= commission rate*sales
Total commission= 0.11*7,200
Total commission= $792
Last week Alexander earned $792 in commissions.
Yvonne ran up 12 flights of stairs.
Explanation:
Understand the situation:
Yvonne ran up 1/4 of the total stairs. Afterwards, she walked the REST of the stairs, which is said to be 9 STAIRS. HOW MANY flights of stairs IN TOTAL did she run up?
When she ran the REST of the stairs, it meant she ran the other 3/4 of stairs because:
1 - 1/4 = 3/4
To add someting, that means that the 9 stairs is 3/4 of the total stairs, so lets fins the total stairs using this information:
9 ÷ 3/4 = 12
LETS CHECK IF 9 IS REALLY 3/4 of 12:
12 x 3/4 = 9
