Answer: (x - 1)² + (y - 1)² = 25
<u>Step-by-step explanation:</u>
The formula for a circle is (x - h)² + (y - k)² = r² where
- (h, k) is the center
- r is the radius
Typically, you are given the center and the radius. In this problem, you are given (x, y) so you must plug that into the equation to find r².
Given: (x, y) = (-3, 4) and (h, k) = (1, 1)
(-3 - 1)² + (4 - 1)² = r²
(-4)² + (3)² = r²
16 + 9 = r²
25 = r²
Next, input (h, k) and r² into the equation
(x - 1)² + (y - 1)² = 25
Answer:
<h2>x = 45°</h2>
Step-by-step explanation:
If AC is a supplementary line, then
x + 90° + x = 180°
solution:
2x + 90° = 180° |<em>subtract 90° from both sides</em>
2x = 90° |<em>divide both sides by 2</em>
x = 45°
Answer:
$25.00 + $10x = $115.00
Step-by-step explanation:
We know that the initial charge of joining is $25. Each class costs $10 each. She spent a total of $115. What we don't know is how many classes she took. With this equation, we can easily find out how many classes she took.
Answer:
x > 5
Step-by-step explanation:
<em><u>Subtract 7 from both sides, like so:</u></em>
x + 7 > 12
- 7 - 7
________
x > 5
