6x - 2y = 10
-2y = -6x + 10...reduce by dividing by -2
y = 3x - 5....slope = 3 and y int = -5
y = 3x + 2 ...slope = 3, y int = 2
These lines are parallel. Parallel lines will have the same slope, but different y int's. There is no solution to this because ur lines never intersect.
Mark's answer is correct
Answer:

Step-by-step explanation:
Simple interest is where interest is only accumulated on the principle, so at 4.5% for 5 years, 22.5% is added to the principal.
Answer:
4x-12 or 4(x-3)
Step-by-step explanation:
9x+9+2x-7(3+x)
9x+2x+9-21-7x
11x-12-7x
11x-7x-12
4x-12
Answer:
300
Step-by-step explanation:
15 * 20 = 300
she spent 3/5 * 300 = 180
and saved 2/5 * 300 = 120
Answer:
x = -14
Step-by-step explanation:
x + 6 = 4x/7
7x + 42 = 4x
7x - 4x = -42
3x = -42
x = -42 ÷ 3
x = -14
