$4x-40y=4\\40y=4x-4\\y=\frac{4}{40}-\frac{4}{40}\\y=\frac{1}{10}x-\frac{1}{10}\\$

Here, 1/10 is the slope and 1/10 is the Y intercept.

Which is the graph of 2x + 3y >-3?

Cerrena [4.2K]

Answer:

The third graph is correct for the inequality 2x + 3y > -3

Step-by-step explanation:

The slope of the graph is –2/3.

The y-intercept is –1

The area above the dashed be line is shaded.

To verify, choose a coordinate in the shaded area, substitute the values for x and y. Calculate and check.

For example: (1,1)

2(1) + 3(1) > –3

2 + 3 > –3

5 > –3 True.

A cylinder has 18 inch diameter and is 15 inches tall it is filled to the top with water a 6 inch diameter ball is in place with

k0ka [10]

Answer: $1,179\pi\ in^3$

Step-by-step explanation:

The volume of a cylinder can be calculated with the following formula:

$V=\pi r^2h$

Where "r" is the radius and "h" is the height.

The volume of a sphere can be found with this formula:

$V=\frac{4}{3}\pi r^3$

Where "r" is the radius.

Then, volume of the empty cylinder is:

$V_c=\pi (\frac{18\ in}{2})^2(15\ in)\\\\V_c=1,215\pi \ in^3$

And the volume of the ball is:

$V_b=\frac{4}{3}\pi (\frac{6\ in}{2})^3\\\\V_b=36\pi \ in^3$

Finally, you need to subtract them in order to calculate how much water is in the cylinder:

$1,215\pi \ in^3-36\pi \ in^3=1,179\pi\ in^3$
