Answer:
The square root of 7 and the square root of 2
Step-by-step explanation:
5/9(f-32)=c
5/9f+5/9*-32=c: step 1
5f/9-160/9=c: step 2
5f/9-160/9+160/9=c+160/9: step 3
5f/9=160/9*9+c*9: step 4
5f/5=160/5+9c/5: step 5
f=32+(9c/5): answer
Answer:
<em>x and y are not in direct variation.</em>
Step-by-step explanation:
<u>Direct Variation</u>
Two variables x and y have a direct proportion or variation if:
y = k.x
Where k is the factor of proportionality. The value of k must be constant for every ordered pair (x,y). If only one of them does not have the very same k, then the relationship is not direct.
The value of k can be solved from the equation:

Let's substitute the given points in the table:
<em>(2,8)</em>

k = 4
<em>(4,16)</em>

k = 4
<em>(6,30)</em>

k = 5
Since the value of k is not constant, then x and y are not in direct variation.
