Point (21, 13)
Point (3, 13)
<u>Step 2: Find distance </u><em><u>d</u></em>
Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>

- [√Radical] Add:

- [√Radical] Evaluate:

The <em><u>correct answer</u></em> is:
The equation has no solution; therefore, the system of equations has no solution.
Explanation:
When solving a system of equations, after we combine the equations, if we find that there is no solution, that means that there is no solution to the entire system of equations.
Answer:
-7/3
Step-by-step explanation:
slope formula:
y = mx + b
the m is the slope value
Step-by-step explanation:
- 7x + 3x - 18 = 6(x + 3) === Given
- 10x - 18 = 6(x + 3) === Combine Like Terms === 7x + 3
- 10x - 18 = 6x + 18 === Distributive Property === 6(x + 3)
- 10x - 18 - 6x = 18 === Subtraction Property of Equality === -6x both sides
- 4x - 18 = 18 === Combine Like Terms === 10x - 6x
- 4x = 18 + 18 === Addition Property of Equality === +18 both sides
- 4x = 36 === Combine Like terms === 18 + 18
- x = 36 / 4 === Division Property of Equality === /4 both sides
- x = 9 === combine like terms??
That doesn't use the multiplication property but that's all of the rest of them.
