X2 −2x + y2 − 6y = 26 what is the radius

Thepotemich [5.8K]

$r > 0\\\\(x-a)^2+(y-b)^2=r^2\\\\x^2-2x+y^2-6y=26\\\\ (x-1)^2-1+(y-3)^2-9=26\\\\ (x-1)^2+(y-3)^2-10=26 \ |+10\\\\(x-1)^2+(y-3)^2=36\\\\ r^2=36 \ \Rightarrow \ r=6$

Lei pre sold 32 carnations for a fundraiser, then she sold c more carnations on the day of the fundraiser. She earned 0.25 dolla

Lina20 [59]

Answer: $0.5 * (16 + 0.5c)$

Step-by-step explanation:

Creating identical expressions involves changing quantities in a way that preserves the end values specified in the equation.

For instance, if Lei sold 4 carnations:

$8 + 0.25 (4) = 9\\\\0.25 * (32 + 4) = 9$

In the second equation listed, the expression (8 + 0.25c) was multiplied by 4, then by 0.25, for a total multiplicand of 1.

You can make a third equation through the same method. I'll multiply (8 + 0.25c) by 2, and then multiply that expression by 0.5 to keep the multiplicand unchanged:

$0.5 * (16 + 0.5c)$

If Lei sold 4 carnations:

0.5 * (16 + 2) = 9

This equation represents the same quantities as the other equations.
