I have one third gallon of juice and one sixth gallon. How many more gallons is need to make three gallons

charle [14.2K]

Answer:

2.5 gallons

Step-by-step explanation:

Make the denominators of the fractions the same and combine them

$\frac{1}{3} =\frac{2}{6}$

$\frac{2}{6} +\frac{1}{6} =\frac{3}{6}$

Then simplify the fraction

$\frac{3}{6} =\frac{1}{2}$

Then subtract how many gallons you have from how many you want

$3 -\frac{1}{2} = 2\frac{1}{2}$

You will need 2.5 gallons to make 3 gallons

7. Use the quotient rule to simplify the following expression. Assume that x>0.

NeTakaya

Quotient rule says we can divide 192 and 3 because they are both under the radical. This gives us the square root of 64.

We can also divide x^3 and x to get x^2.

The square root of 64x^2 is 8x

Can anyone answer this for me?

Sunny_sXe [5.5K]

Answer:

y = 2 - $x^{2}$

Step-by-step explanation:

$x^{2}$ results in a parabola (U-shape). Adding a negative in front of it flips the parabola to look like an upside-down U.

The 2 makes it shift up two decimal spots to (0,2).
