Answer:

I think it is 20.75°

Step-by-step explanation:

An interesting problem!

the m arcVYX = 282° so the m arcVYXV must equal 360°

so the m arcVX must equal 360 - 282 = 78°

I beleive m angle UVX - m arcVX = 78°

78 = 4x - 5

83 = 4x

20.75° = x

I don't like this answer. I would normally exspect whole numbers for most algebra problems

Which ordered pairs in the form (x, y)(x, y) are solutions to the equation

Scilla [17]

4x - 5y = 24

4(6) - 5(0) = 24
24 - 0 = 24
24 = 24 (correct)....so (6,0) is a solution

4(1) - 5(-4) = 24
4 + 20 = 24
24 = 24 (correct)...and (1,-4) is a solution

Which is the best example of a down payment?

Maru [420]

Answer:

Step-by-step explanation:

Proof by some contradictions:

D is not a good example because she does not pay anything upfront

B is not a good example because he pays <u>everything </u>upfront with some of the money from a third party

A is not right because the 500 is a security deposit, which is a different concept from a down payment

Therefore the answer should be C, where money is payed upfront and payed after he receives the product.

What is a equation of the line that passes through the point (−5,7) and is parallel to the line x+5y=10

Answer:

$\displaystyle y = -\frac{1}{5} x +6$

Step-by-step explanation:

<u>Equation of a LIne</u>

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

We are required to find the equation of a line that passes through the point (-5,7) and is parallel to the line x+5y=10.

This information provides us the values of h=-5 and k=7. We now need to determine the value of the slope.

Two parallel lines have equal values for the slopes. The equation of the line

x + 5y = 10

Can be rearranged in such a way we can find its slope. Let's solve it for y:

5y = -x + 10

$y = -\frac{1}{5}+2$

The slope of this line is -1/5 and that is the same value of the slope of our line, thus its equation is:

$\displaystyle y - 7 = -\frac{1}{5} ( x + 5 )$

Adding 7:

$\displaystyle y = -\frac{1}{5} ( x + 5 )+7$

Operating:

$\displaystyle y = -\frac{1}{5} x + -\frac{1}{5}*5 +7$

$\displaystyle y = -\frac{1}{5} x -1+7$

$\boxed{\displaystyle y = -\frac{1}{5} x +6}$
