Answer:

C. (4y - 1)(3y + 2).

Step-by-step explanation:

12y^2 + 5y - 2

Use the ac method.

a = 12 ( the leading coefficient) and c = -2 (the constant last term).

a * c = -24.

We need 2 numbers whose product is c (-2) and whose sum is +5 (the coefficient of y).

They are + 8 and -3, So we write the original expression as:

12y^2 - 3y + 8y - 2 Now we factor this by grouping:

= 3y(4y - 1) + 2(4y - 1) The 4y - 1 is common so:

= (4y - 1)(3y + 2).

Write an equation in slope-intercept form of the line.

alexira [117]

Answer:

y=x-3

Step-by-step explanation:

To find slope, use m=y2-y1/x2-x1, using values of x and y from two different points. Once you have found slope, take another point and use the point-slope equation y-y1=m(x-x1) and substitute in slope for m and the point for x1 and y1. Isolate y by subtracting y1 from both sides.

What additional piece of information must be known in order to calculate the volume of the cylinder below?

djyliett [7]

For this case we have that by definition, the volume of a cylinder is given by:

$V = \pi * r ^ 2 * h$

Where:

r: It is the radius of the cylinder

h: It is the height of the cylinder

We have as data, observing the figure, that they give us the radio. Then, the height is missing.

Answer:

Option B
