Answer:
y = 7 
Step-by-step explanation:
Use the given ordered pairs to find a and b
Using (0, 7 ), then
7 = a  (
 (  = 1 ), thus
 = 1 ), thus
a = 7
y = 7 
Using (5, 1701 )
1701 = 7  ( divide both sides by 7 )
 ( divide both sides by 7 )
243 =  ( take the fifth root of both sides )
 ( take the fifth root of both sides )
b = ![\sqrt[5]{243}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B243%7D) = 3 , thus
 = 3 , thus
y = 7  
 
 
        
             
        
        
        
Answer:
14cm, 16 cm, 18 cm
Step-by-step explanation:
Note that
= a:b: c = 7:8:9
We have to find the sum of the proportion
Sum of proportion = 7 + 8 + 9
= 24
Length of side a
7/24 × 48 = 14 cm
Length of side b
8 /24 × 48 = 16cm
Length of side a
9/24 × 48 = 18 cm
What are the lengths of the sides?
The lengths of the sides of the triangle in cm are
14cm, 16 cm, 18 cm
 
        
             
        
        
        
For this case we can make the following rule of three:
 1 cup ----------------> 128 grams
 x ----------------------> 192 grams
 From here, we clear the value of x.
 We have then:
 x = (192/128) * (1)
 x = 1.5
 x = 1 1/2

Well - I mean. If every lunch costs $4 that means that the relationship should be linear. 
You used to be able to draw graphs. But plot it out.
