What is the general form of the equation of a circle with center at (a, b) and radius of length m?

In the problem, it says that the center of the circle is at point (a,b) and has a radius of length m. In this case, the standard form of the circle is represented by the equation (x-h) ^2 + (y-k)^2 = r^2. Upon substitution, (x-a) ^2 + (y-b)^2 = m^2.This is equal to x2 - 2ax + a2 + y2 -2by + b2 = m2. The equation that is similar here is A

Answer:

1) $x=\dfrac12$

2) $n = -3 \ \ \textsf{and} \ \ m = -4$

3) see below

4) A: 0 = 1

Step-by-step explanation:

<u>Question 1</u>

$15-0.5(4x-2)+4x=17$

$\implies 15-2x+1+4x=17$

$\implies 2x+16=17$

$\implies 2x=1$

$\implies x=\dfrac12$

<u>Question 2</u>

$\textsf{rearrange} \ n=m+1 :$

$\implies -m=-n+1$

$\textsf{add equations} \ -m=-n+1 \ \textsf{and} \ m=2n+2:\\$

$\implies0=n+3$

$\implies n=-3$

$\textsf{substitute} \ \ n=-3 \ \ \textsf{into} \ \ m=n-1:$

$\implies m=-3-1$

$\implies m=-4$

<u>Question 3</u>

subtract the second equation from the first

divide both sides by -4

substitute found value for y into first equation

solve for x

<u>Question 4</u>

$3j=k$

$k=3j+1$

$\textsf{rearrange} \ 3j=k :$

$\implies -k=-3j$

$\textsf{add equations}\ -k=-3j \ \ \textsf{and}\ \ k=3j+1:$

$\implies 0=1$

Solution = A

If cade shoots 275 free throw baskets in 2 hours, how many can he shoot in 5 hours

Volgvan

Hey there! :D

Find the unit rate.

275/2= 137.5

Cade shoots 137.5 free throws per hour. Multiply that by 5 for 5 hours.

5*137.5= 687.5

He can shoot 687.5 free throws in one hour. You could just round that to 688.

I hope this helps!
