how can you rewrite the function f(x) = -|x| + 3 as a piecewise-defined function?
Answer:
Step-by-step explanation:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Step-by-step explanation: Its 12 because every hour she earns 12 dollars and as the y changes so will the amount of money she earns Ex: y=2 she earns 24 dollars.
A child is hopping along a sidewalk. The ratio table below shows the comparison between the number of hops and the distance traveled. Hopping Number of hops Distance traveled (ft)
20 30
50 75
80 120
120 ? Which statement correctly explains how to find the distance traveled after 120 hops? Subtract 120 – 75 to get 45, then add that number to 120. Add 30 + 75 + 120. 20 multiplied by 6 is 120, so you can multiply 30 times 6 to find the distance. 30 multiplied by 4 is 120, so you can multiply 20 times 4 to find the distance.
Answer:
i think its C
Step-by-step explanation:
Find the ratio of hops to distance traveled (1: 1.5), then multiply 150 by 1.5.

Money that is collecting interest in a bank account triples in value every 20
years.
When the account was
opened, it had 81, or 34 dollars in it. After 60 years, the
account balance has tripled 3 times, increasing by a factor of 33.
It now has a balance of 34. 33. Expressed as a power, how much money, in
dollars, is in the account after 60 years?

One of the rows in the table has an error and does not have the same ratio as the other rows.
Conversion Chart
Feet
Inches
Row 1
3
36
Row 2
6
72
Row 3
7
94
Row 4
9
108
Which explains how to correct the error in the table?
Row 1 should show 3 feet is equivalent to 32 inches.
Row 2 should show 6 feet is equivalent to 66 inches.
Row 3 should show 7 feet is equivalent to 84 inches.
Row 4 should show 9 feet is equivalent to 104 inches.
Answer:
Row 3 should show 7 feet is equivalent to 84 inches.
Step-by-step explanation:
First divide 36 and 3 to find the constant proportion. Which you get 12
Now multiply 12 x 3 , 12 x 6, 12 x 7, and 12 x 9
You should be able to find the incorrect answer which is row 3
12 x 7 actually equals 84 not 94
Hope this makes sense!
