Answer:

(x-6)^2 + (y+8)^2 = 25

Step-by-step explanation:

The equation for a circle can be written as

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

where (h,k) is the center and r is the radius

The diameter is 10 so the radius is 10/2 =5

the center is 6,-8

(x-6)^2 + (y- -8)^2 = 5^2

(x-6)^2 + (y+8)^2 = 5^2

(x-6)^2 + (y+8)^2 = 25

Answer:

-7/10

Step-by-step explanation:

To find the slope of a line, you need to find the $\frac{rise}{run}$ between two points. I will be using the points (-3, 5) and (7, -2).

$\frac{rise}{run}$ = $\frac{-2-5}{7-(-3)}$

= $\frac{-7}{10}$

= -7/10

Riley and Erik have earned a total of 135 tokens to buy items in the school store. The ratio of the number of tokens that Riley

lisabon 2012 [21]

Answer:

<em>Riley has 72 tokens</em>

Step-by-step explanation:

<u>System of Equations </u>

We have two conditions for the tokens Riley and Erik have earned. Let's call x and y to the number of tokens of Riley and Erik respectively. The first condition states that

$x+y=135$

Solving for y

$y=135-x$

The second condition is that the ratio of the number of tokens that Riley had to the number of tokens that Erik has is 8 to 7. It's written as

$\displaystyle \frac{x}{y}=\frac{8}{7}$

Or equivalently

$7x=8y$

Replacing y from the first equation

$7x=8(135-x)$

Operating

$7x=1080-8x$

Simplifying

$15x=1080$

$\boxed{x=72}$

Riley has 72 tokens

Ppppppppppllllllllls I need helppppppp

Phantasy [73]

Answer:

ΔABC≅ΔDEC by AAS

Step-by-step explanation:

You can use the AAS method of congruency.

Since you already have <BAC and <EDC congruent to eachother, and sides BC and EC congruent to each other, you only need that one remaining angle in between. <ACB can be proven congruent to <DCE by the Vertical Angles Theorem, and that gives you the AAS you need to prove that these two triangles are congruent

Hope this helped.
