Step-by-step explanation:

As per the given condition: G.O is going on a hike in the mountains on a hot summer day he has 4/5 gallon of water that he split into 4 bottles.

⇒ in 4 bottle  he has \frac{4}{5} gallon of water.

Unit rates defined as when are expressed as a quantity of 1, such as 3 feet per second or 4 miles per hour, then they are called unit rates.

By unit rate definition,

In 1 bottle he has = \frac{4}{5} \times \frac{1}{4} = \frac{1}{5} gallon of water.

therefore, the gallon in each bottle in fraction is, \frac{1}{5}

Find the y-intercept for the parabola defined by the equation y=x^2-x-12
o-na [289]

Answer:

The y-intercept is (0,-12).

Step-by-step explanation:

Given equation is y=x^2-x-12.

Now question says to find the y-intercept of the given parabola y=x^2-x-12.

We know that y-intercept means the y-value when x-value equals 0

so let's plug x=0 into given equation y=x^2-x-12  then solve that for y.

y=x^2-x-12

y=0^2-0-12

y=0-0-12

y=-12

Hence the y-intercept is (0,-12).
