Answer:
x = 6.25
Step-by-step explanation:
Suppose y = 2x - 2.5. Find x when y = 10
this gives us the equation:
10 = 2x - 2.5
add 2.5 to both sides
2x = 12.5
divide both sides by 2
x = 6.25

You missed a number how many meters of cloth
Answer: the equation is 2n-10
-6x <= 4x + 2
Subtract 4x from both sides
-10x <= 2
Divide -10 on both sides
Final Answer: x >= -1/5
Answer:
(x + 2)² + (y - 1)² = 25

Circle Center Formula: (x - h)² + (y - k)² = r²
- <em>(h, k)</em> is center
- <em>r</em> is radius
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>(h, k)</em> = (-2, 1)
<em>r</em> = 5
<u>Step 2: Find Equation</u>
- Substitute in variables [Circle Center Formula]: (x - -2)² + (y - 1)² = 5²
- Simplify: (x + 2)² + (y - 1)² = 25
