Prime numbers are numbers that we can only divide by 1 and it self.
example- 2 can only be divided by 2 and 1
composite numbers are numbers we can divide by two or more numbers
example- 4 can be divided by 1,2 and 4.
(3,14) because when you plug in the x and y values you don’t end up with a true statement.
F(x)=2(3)+9
F(x)=6+9
F(x)=15
14 does not equal 15

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
3(2x - 1) - 11x ≤ -3x + 5
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Distributive Property Distribute 3: 6x - 3 - 11x ≤ -3x + 5
- [Subtraction] Combine like terms: -5x - 3 ≤ -3x + 5
- [Addition Property of Equality] Add 5x on both sides: -3 ≤ 2x + 5
- [Subtraction Property of Equality] Subtract 5 on both sides: -8 ≤ 2x
- [Division Property of Equality] Divide 2 on both sides: -4 ≤ x
- Rewrite: x ≥ -4
