Answer:
Slope of line 1 = 3
Slope of line 2 = 3
Slope of line 3 = -1/3
Line 1 and 2 are parallel
Line 1 and 3 are perpendicular
Line 2 and 3 are perpendicular
Step-by-step explanation:
Find the slope of each line by using this equation:
lines are parallel if they have the same slope and line are perpendicular in they have opposite reciprocal slopes. (-1/3 is the opposite reciprocal of 3).
Hope this helps!
Answer: A
Step-by-step explanation:
This is because...
1st. Simplify both sides of the equation (distribute the 4 and combine like terms)
6 + -x = 20 + 4x + -4 (distributed 4)
-x + 6 = 4x + 16 (combined like terms)
2nd. Subtract 4x from both sides.
3rd. Subtract 6 from both sides.
4th. Divide both sides by -5.
3 + 5 = 8
8 - 5 = 3
3 - 3 = 0
New value =
29,000 + Percentage increase =
29,000 + (- 5% × 29,000) =
29,000 - 5% × 29,000 =
(1 - 5%) × 29,000 =
(100% - 5%) × 29,000 =
95% × 29,000 =
95 ÷ 100 × 29,000 =
95 × 29,000 ÷ 100 =
2,755,000 ÷ 100 =
27,550
