Perpendicular means the slopes are opposite inverse of each other
If line a is slope 2, the perpendicular line to Line a would have a slope - 1/2
Difference in y over difference in x gives slope. If they are opposite inverse values the lines are perpendicular. ( in this case the answer is true.)
Answer:
the third one
Step-by-step explanation:
Answer:
11a. 15x + 6
11b. x + 8 < 16 or x + 8 - 16
12. 3x + 15 + 5x = 8x + 15
13. 7x + 31
Step-by-step explanation:
Answer:
8,246,160
Step-by-step explanation:
Population density
= people/area
Given
Population density of New York = 17,620 and
Area = 468 square mile
Therefore,
17620 = people /468
Cross multiply
People = 17620 x 468
= 8246160
There are 8,246,160 people in New York
Subtract 3 from both sides
-12u = 8v + 1 - 3
Simplify 8v + 1 - 3 to 8v - 2
-12u = 8v - 2
Divide both sides by -12
u = - 8v - 2/12
Factor out the common term 2
u = - 2(4v - 1)/12
Simplify 2(4v - 1)/12 to 4v - 1/6
u = - 4v - 1/6
