Write an equation for the translation of y=|x|. 2 units down.

Bezzdna [24]

B. Y = <span>|x| - 2
when moving left or right...meaning moving horizontally.......the number is added inside the parenthesis.

This one is moving up or down ....meaning moving horizontally........so the number is added outside the parenthesis. If it moves up then add(+)..........if it moves down then subtract(-). The formula used for horizontal shifts is, y=lXl + k
.Here k will become negative or remain positive based on the given data.

Now,
It's a horizontal shift, so we can eliminate C and D.
It moves down so we will subtract and therefore we can eliminate A

so the answer is B.
lets check our answer by using the formula

Y = lxl + k
moves 2 units down so our k = (-2)
Y = lxl + (-2) [substitute k]
Y = lxl - 2

HELP HELP ME PLEASE!!!

Use the cone formula:
$V = \pi r^{2} \frac{h}{3}$
And so:
$Area = \pi * 150^{2} * \frac{240}{3} = 5654866.7 inches^{2}$
5654866.7 / 12000 = 471,
So the answer is 471 weeks.

Hope this helps.

Answer:

$A=376.99\ cm^2$

Step-by-step explanation:

We need to find the lateral surface area of the cylinder of radius 6 cm and height of 10 cm.

We need to find the lateral surface area of the cylinder. The formula for the lateral surface area of a cylinder is given by :

$A=2\pi rh\\\\A=2\pi \times 6\times 10\\A=376.99\ cm^2$

So, the lateral surface area of the cylinder is $376.99\ cm^2$ .

Solving for Y. Write the following equations in slope-intercept form.

asambeis [7]

1) 3x - 2y = -16 Subtract 3x from both sides
-2y = -3x - 16 Divide both sides by -2
y = $\frac{3}{2}$ x + 8

2) 9x - 7y = -7 Subtact 9x from both sides
-7y = -8x - 7 Divide both sides by -7
y = $\frac{8}{7}$ + 1

3) x - 3y = 6 Subtract x from both sides
-3y = -x + 6 Divide both sides by -3
y = $\frac{1}{3}$ - 2
