Answer:
u can ask if u didn't understand !
Answer:
25 because 50 minus 25 is 25
Answer:
y ≤ −2x + 3
y ≤ x + 3
Step-by-step explanation:
they both share the slope of 3.
line a has a slope of -2
line b has a slope of 1
the sign ≤ means that the inequalities have a solid line and there below the line.

Radius of a Circle Formula: r = d/2
Area of a Circle Formula: A = πr²
Step-by-step explanation:
<u>Step 1: Define</u>
Diameter <em>d</em> = 18 units
<u>Step 2: Manipulate Variables</u>
Radius <em>r</em> = 18 units/2 = 9 units
<u>Step 3: Find Area</u>
- Substitute in <em>r</em> [Area of a Circle Formula]: A = π(9 units)²
- [Area] Evaluate exponents: A = π(81 units²)
- [Area] Multiply: A = 81π units²
