Answer: Well... I know that after 11 weeks the money will have increased by 330 dollars, equaling a total of 880 dollars.

Step-by-step explanation: The equation I used was:

( 30 x w ) + 550 = s

( 30 x 11 ) + 550 = 880

What are the coordinates of the center and the

Misha Larkins [42]

Answer: The coordinate of the center is (4,-3)

radius = 8

Step-by-step explanation:

Given ;

$x^{2} +y^{2}=8x-6y+39$

re - arranging , we have

$x^{2} +y^{2}-8x+6y-39=0$

comparing with the general equation

$x^{2} +y^{2}+2gx+2fy+c=0$

This means that

$2gx = -8x$

$2g=-8$

$g=-4$

also

$2fy=6y$

$2f=6$

$f=3$

$c=-39$

The coordinate of the center is (-g,-f)

Therefore;

the coordinate of the center = (4,-3)

the formula for calculating r is given by:

$r = \sqrt{g^{2}+f^{2}-c}$

$r = \sqrt{16+9+39}$

$r=\sqrt{64}$

$r=8$

METHOD 2

$x^{2} +y^{2}-8x+6y-39=0$

using completing the square method , we have

$x^{2} -8x+y^{2}+6y-39=0$

completing the square , we have

$(x-4)^{2}+(y+3)^{2} = 39 +4^{2}+3^{2}$

$(x-4)^{2}+(y+3)^{2}=64$

comparing with the general equation

$(x-a)^{2}+(y-b)^{2}=r^{2}$

where a and b are the coordinate of the center , that is

the coordinate of the center is ( 4 , -3)

$r^{2}=64$

$r=8$

What is the scale factor equation?

zhuklara [117]

A scale factor is a number which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x.

What is the slope and Y intercept?

kirill [66]

Answer:

Y intercept = (0,10)

slope is 4

Step-by-step explanation:

Ok so Start with y intercept. That’s the point it crosses the y axis. So that would be ( 0, 10). To find slope, you do rise/run. Or how far up, and how far right. take two points (0,10) and (1, 14)

14-10

——-

1-0

= 4/1 = 4

so the slope is 4.
