Answer:

Step-by-step explanation:

The equation can be rearranged to slope intercept form of

y = 4x - 2

We know that the y-intercept is -2 because it is the leftover part, and the slope is 4 because it is 4x.

You can plug in an x-value from the table into the equation, and if it is correct, all the values should end up with the same and correct y-value.

-5 times 4 is -20

-20 -2 = -22.

Correct so far

0 times 4 is 0.

0 - 2 = -2.

Correct so far.

3 times 4 is 12.

12 - 2 = 10.

Correct!

Checking B:

-22 times 4 = -88.

-88 - 2 = -90.

Wrong.

Checking C:

-5 times 4 = -20.

-20 - 2 = -22.

Wrong.

It must be A

A video game system and several games are sold for $700. The cost of the games is three times as much as cost of the system. Fin

Answer:

cost of system is $175 and cost of the games is $525

Step-by-step explanation:

Let us take the cost of the system to be X.The games cost 3 times as much as the system and are therefore given 3X. The total cost of the system and the games is $700.Therefore,we form the equation 3X+X=$700.Meaning that 4X=$700 and X is equal to $175.The cost of the system is X therefore it is $175 and the cost of the games is 3X and is therefore $525.

The main show tank has a radius of 60 feet and forms a quarter sphere where the bottom of the pool is spherical and the top of t

svetlana [45]

The given radius is = 60 feet

The volume of the sphere is given by = $\frac{4}{3} \pi r^{3}$

So we will find the volume of the sphere using radius as 60 and pi as 3.14

Volume = $\frac{4}{3}*3.14*60*60*60$ = 902059.20 cubic feet

As quarter of anything is defined as its one-fourth part, so here the volume of the quarter of sphere can be calculated by finding one fourth of the calculated volume.

So volume of quarter sphere = $\frac{902059.20}{4}$
