Answer:
 25%
Step-by-step explanation:
Given parameters: 
Amount earned by Jessica per month = 800 
Total savings target per year  = 2400
Unknown: 
Percentage of savings = ? 
Solution: 
The total earning per year will be the amount earned per month multiplied by the total number months;
  Amount earned in a year = 12 x 800  = 9600 
Let the percentage of savings per year  = y% 
   Now; 
               2400 = 
 x 9600 
                   y = 25%
 
        
             
        
        
        
Answer:
A. 
 = Cube root of 4.
Step-by-step explanation:
We have been given an expression 
. We are asked to find the equivalent expression for our given expression.
Using exponent property 
, we will get,
![2^{\frac{2}{3}}=\sqrt[3]{2^2}](https://tex.z-dn.net/?f=2%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%3D%5Csqrt%5B3%5D%7B2%5E2%7D)
![2^{\frac{2}{3}}=\sqrt[3]{4}](https://tex.z-dn.net/?f=2%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%3D%5Csqrt%5B3%5D%7B4%7D)
Upon looking at our given choices, we can see that option A is the correct choice.

Answer:
y = 3x + 15
Step-by-step explanation:
1. Find the reciprocal of the slope and change signs: -3
2. y = 3x + b
3. Plug in x and y --> b = 15
4. Make your equation using y = mx + b: y = 3x + 15
