What's an equation that the passes through (-6,4) and is parallel to y=1/2x+8

deff fn [24]

By definition, if two lines share the same gradient, they are said to be parallel. So, we know for this equation, it must have a gradient of 1/2.

Now, since the point (-6, 4) passes through the line, we know it must satisfy the equation. Since we have a gradient/slope and a point, we can use the point-gradient form:

$y - y_1 = \frac{1}{2}(x - x_1)$ , where $(x_1, y_1)$ represents the points being passed through.

$y - 4 = \frac{1}{2}(x + 6)$
$2y - 8 = x + 6$
$2y = x + 14$
$y = \frac{1}{2}x + 7$

Which of the following is the equation of a circle with center (5, -2) and a radius of 3?

ryzh [129]

EQUATION OF A CIRCLE = (x-h)² + (y-k)² =r²

Since the center of the cercle is in O, then h=5 & k=-2

(x-5)² + (y+2² =9

<u>Answer:</u>

3/5

<u>Step-by-step explanation:</u>

We are to find the similarity ratio of a cube with volume $729 m^3$ to a cube with volume $3375 m^3$ .

We know the formula for the ratio of two cubes:

$\frac{V_1}{V_2} =k^3$

where $k$ is the similarity ratio of the two cubes.

Substituting the given values in the formula to find $k$ :

$k^3 = \frac {729} {3375}$

$k^3 = \frac {27} {125}$

$k^3 = (\frac {27} {125})^3$

$k=\frac{3}{5}$

Therefore, the similarity ratio of the two cubes is 3/5.

Mary Hernandez had a policy with a $500 deductible which paid 80% of her covered charges less deductible. She had medical expens

12345 [234]

A.) The insurance company's payment is 80% of the total minus the $500 deductible, so:
(10000 - 500) * .8 = 7600

B.) To find the Copay, you do almost the same thing:
(10000 - 500) * .2 = 1900

C.) Mary's Total Cost: 1900 + 500 = 2400.00
