Answer:
no u may nit know this answet
Answer:
Option C. Yes; y=2x
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
so
In this problem
For x=0, y=0
That means ----> the line passes through the origin
<em>Find the value of k</em>
For x=2, y=4
----> 
For x=4, y=8
----> 
The values of k are equal
therefore
The table represent a direct variation
The equation is equal to

Answer:
122
Step-by-step explanation:
1.8 times 50 is 90, and 90 plus 32 is 122
Answer:
-12r2-9r-6
Step-by-step explanation:
-distribute the subtraction symbol to the second group of numbers
-(9r2+7r+2) = (-9r2-7r-2)
-then combine each term together (-3r2-2r-4)+(-9r2-7r-2)
= -12r2-9r-6
