The answer would be 32. :) This is because 5x8=40, so 8x4=32.

Find the slope if it exists, of the line containing the pair of points (5,8) and (10,-7)

Contact [7]

Answer:

slope: -1/6

Step-by-step explanation:

to find the slope of a line we can use the formula (y2-y1)/(x2-x1)

this means ththe second y subtracted by the first year divided by the second x subtracted by the first x

when plugged in you get (10-8)/(-7-5)

when simplified it becomes 2/-12 and then -1/6

Using the following equation, find the center and radius of the circle. You must show all work and calculations to receive credi

adoni [48]

Answer:

$r = 4$

The center is:

(2, -4)

Step-by-step explanation:

We have the following equation

$x^2 - 4x + y^2 + 8y = -4$

The general equation of a circle has the following form

$(x-h)^2 + (y-k)^2 = r^2$

Where r is the radius and the point (h, k) is the center of the circle

To transform the given equation in the general equation of a circumference we must use the method of square completions

Step 1

$(x^2 - 4x) + (y^2 + 8y) = -4$

<u>Step 2</u>

<u> </u>Add and subtract $(\frac{b}{2})^2$ For an equation of the form

$ax^2 +bx +c$

$(x^2 - 4x +4)-4 + (y^2 + 8y +16) -16= -4$

<u>Step 3 </u> Factor the expressions within the parentheses

$(x-2)^2-4 + (y+4)^2 -16= -4$

<u>Step 4 Simplify</u>

$(x-2)^2 + (y+4)^2= -4+16+4$

$(x-2)^2 + (y+4)^2= 4^2$

Finally

$r = 4$

The center is:

(2, -4)
