Answer:
x = 0.6y.
Step-by-step explanation:
x = ky is direct variation where k is some constant;
Now we find k:-
Substituting for x and y:
9 = k*15
k = 9/15 = 0.6
So the equation is
x = 0.6y.
It's a rational number. 9 is a perfect square. What you have asked is written as -sqrt(9), which can be written as -sqrt(3*3) which is - 3. That's perfectly OK. What would not be OK is something like -sqrt(10) which is irrational because it cannot be represented as a fraction or a whole number or a repeating decimal or a decimal that terminates.
Rx + h = sx - k
rx - sx = -k -h
x ( r -s ) = -k -h
x = -k -h / r -s Ans
8675 ÷ .5= 17350
You could also multiply by 2 to check your answer
17350 * .5= 8675
You could also divide by 2.
