Hi there!
Let r be the number of matches that Rebecca's team won.
We know that Katheryn's team won 9 more matches than Rebecca's team, and we know that Katheryn's team won 52 matches.
Using this given information, we can create the following equation.

If you wish to solve this, we can subtract both sides by 9 to get the following value for r.

Have an awesome day! :)

Answer:
(x + 1)^2 + (y - 2)^2 = 3^2 = 9
Step-by-step explanation:
The standard equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2.
Here, h = -1, k = 2 and r = 3, so the equation of this particular circle is
(x + 1)^2 + (y - 2)^2 = 3^2 = 9.
Answer:
0.034921 miles or 1843774 feet tall
Step-by-step explanation:
Using trigonometric functions we know that
and
where
=angle and r is the hypotenuse of the triangle.
First we will calculate the hypotenuse using the x equation, since we know x = 1 mile (distance from the building on the ground) we have:

Now we will calculate the height of the building using the y equation and so:

The building is 0.034921 miles or approximately 184.3774 feet tall.
The answer is A.
The equation simplifies to y=3x+50.
So, C is already not an option.
Now we just plug in points to see if the point works for the equation.
A-11=3(-13)+50
11=-39+50
11=11
Thus, this point falls on the line of this equation and is a point.
So, the answer is A.
I hope this helps!
