f(x)=\dfrac{x}{2}-3=\dfrac{1}{2}x-3\\\\g(x)=4x^2+x-4\\\\(f+g)(x)=f(x)+g(x)\\\\(f+g)(x)=\left(\dfrac{1}{2}x-3\right)+(4x^2+x-4)=4x^2+1\dfrac{1}{2}x-7

If $y^2= 36$, what is the greatest possible value of $y^3$?
RUDIKE [14]

Answer:

The greatest possible value of y^3=216

Step-by-step explanation:

We have the statement y^2=36, and we have to find the greatest possible value of y^3, first we need to find the value of y.

y^2=36, to get the y by itself on the left side, we need to take the square root of both sides. \sqrt{y^2} =\sqrt{36} The square root of y^2 is y, because y*y = y^2, and the square root of 36 is 6 or -6.

We now need to find the greatest value of y^3. When we plug in 6 to y^3, we get positive 216, and when we plug in -6, we get -216. We need to find the greatest possible value, so in this case we compare 216 and -216, 216 is greater than -216, so the answer would be positive 216.

brad drank 7 cups of juice in 4.5 days which rate represents this situation? Question A 7 Cups/4.5days Question B 7days/4.5cups
Yuki888 [10]
The answer is A: 7 cups/4.5 days.

You see, the unit rate for this would be 1 cup/~0.6 day, so C and D would be incorrect (31.5 is too high for 7). Then, if you read it, it's seven cups, not days.

So, A.
