Answer: option. y=-1.33x; 2.67
Solution:
If y varies directly with x, the relation between y and x is:
y=kx
where k is a constant of proporcionality.
We know y=8 when x=-6. Replacing these values in the equation above:
8=k(-6)
8=-6k
Solving for k: Dividing both sides of the equation by -6:
8/(-6)=-6k/(-6)
-1.33=k
k=-1.33
Then the relation between y and x is:
y=kx→y=-1.33x
What is the value of y when x=-2?
Replacing x by -2 in the formula:
y=-1.33x→y=-1.33(-2)→y=2.66
What we know: Lucy's snake eat's 2 mice a week.
To find the answer, you'll have to multiply 2 by 6.
So, since Lucy's snake eats 2 mice a week for 6 weeks.
To find the amount of mice her snake has eaten in the past 6 weeks you'll have to multiply 2 and 6.
2x6=?
------------------------------------------------------------------
The first week the snake ate 2 mice.
The second week the snake ate 2 mice.
The third week the snake ate 2 mice.
The fourth week the snake ate 2 mice.
The fifth week the snake ate 2 mice.
The sixth week the snake ate 2 mice.
Your answer would be: 12
Forgive me if this is wrong. I haven't done stat in a year, but comment if you need clarification!

<span>6^1/3 * 6^1/4 = 6^x/y
The key to solving this problem is understanding properties of exponents:
If you are multiplying two powers with the same base (in this case the base is 6), the result is the base raised to the power of the two exponents added together.
6^1/3+1/4 = 6^x/y
6^7/12 = 6^x/y
So the product would be 6^7/12
x = 7
y = 12</span>
