As you can see, every time x increases by 2, y decreases by 5.

So, we have

$m=\dfrac{\Delta y}{\Delta x}=\dfrac{-5}{2}=-2\dfrac{1}{2}$

PLEASE HELP!!! Given angle circled dash=208° and a right triangle inscribed within a circle of radius 5, what is the value of x

natta225 [31]

Answer:

-4.41

Step-by-step explanation:

208° is a 3rd-quadrant angle, so its x-coordinate will be negative. Your calculator can tell you that 5 times the cosine of this angle is -4.41, or you can refer to a diagram.

I 8. Classify 8 as a perfect square, a perfect cube, both, or neither.

Murljashka [212]

Answer:

It's a perfect cube, but not a perfect square.

Step-by-step explanation:

2^3 = 8, meaning 8 is a perfect cube. But since 2^2 = 4 and 3^2 = 9, and 8 is in between, 8 is not a perfect square.

I hope this helped.

Follow the process of completing the square to solve x2 - 10x + 8 = 0. How will the left side of the equation factor in step 5?

jasenka [17]

Answer:

$x=5(+/-)\sqrt{17}$

Step-by-step explanation:

we have

$x^{2}-10x+8=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$x^{2}-10x=-8$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$x^{2}-10x+5^{2}=-8+5^{2}$

$x^{2}-10x+25=-8+25$

$x^{2}-10x+25=17$

Rewrite as perfect squares

$(x-5)^{2}=17$

Take square root both sides

$(x-5)=(+/-)\sqrt{17}$

Adds 5 both sides

$x=5(+/-)\sqrt{17}$
