I'm really stuck on this math problem. I never learned this in school. Can someone please help me out? Thank you

Hehe, these are fun to do. There are two ways to do this kind of problem. You can use the pythagorean theorem or we can use the distance formula.
Distance formula:
$d= \sqrt{(x2-x1)^2+(y2-y1)^2}$

Pythagorean Theorem:
$a^2+b^2=c^2$

Distance formula is better if you're finding distance between two coordinates. The Pythagorean Theorem only really works for independent values. If I had 2 sides of a triangle, and I needed to find the third, I'd use this equation to find it. In this case, we'll use the distance formula.

I'll work the first one out for you:
x1 y1 x2 y2
(3, 2) & (7, 4)

$d= \sqrt{(7-3)^2+(4-2)^2}$
v
$d= \sqrt{(4)^2+(2)^2}$
v
$d= \sqrt{(16+4}$
v
$d= \sqrt{20}$

There's your answer!

How do you sole this question kelpie sold cameras on her web site. She bought the cameras for $65 each included a 60% markup to

postnew [5]

So 65 dollars was what she paid
each camera INCLUDED a 60% mark UP so
she sold each at a 60% markup

65 dollars=100% of origonal camers
she sold them for 100+60=160% of origonal price
65 dollars=100%
percent means parts out of 100 so
160%=160/100=1.6

find 160% of 65
'of' means multiply so
1.6 times 65=104

she sold each camera at $104

What is 27/36 as a mixed number

This fraction cannot be turned into a mixed number but it can be reduced to $\frac{3}{4}$ or 0.75

Which equation best represents the line that is parallel to 3x -4y=7 and passes through the point (-4,-2)? Select two options.

katovenus [111]

Answer:

The equation that best represents the line that is parallel to 3x - 4y = 7 and passes through the point (-4, -2) is y = 3/4x + 1.

Step-by-step explanation:

3x - 4y = 7 and (-4, -2)

First, solve for y in the equation:

3x - 4y = 7

-4y = -3x + 7

4y = 3x - 7

y = 3/4x - 7/4

m = 3/4 (This will be the slope of the parallel line.) and (-4, -2)

Use the point-slope equation to find the equation that will best represent a parallel line:

y − y1 = m(x − x1)

y - -2 = 3/4(x - -4)

y + 2 = 3/4x + 3 (the 4s cancel out)

(3/4 x 4/1 = 3)

y = 3/4x + 1

The graph that I attached is what these two equations would look like graphed. I am not sure what you mean by two options, I'm sorry!
