Answer:
25.) Slope of AB = 5
Slope of CD = -1/5
Perpendicular
26.) Slope of EF = -3/5
Slope of GH = -3/5
Parallel
Step-by-step explanation:
Use this formula to find slope.
Parallel lines have the same slope
Perpendicular lines have the opposite reciprocal and sign
25.)
Plug in AB slope is 5
2 - 7/ 3 - 4 = -5/-1 = 5
Plug in for CD slope is -1/5
3 - 4/ 2 - -3 = -1/5 = -1/5
The lines AB and CD are perpendicular because they have opposite reciprocals and opposite signs.
26.)
Plug in EF slope is -3/5
1 - 4/ 3 - -2 = -3/5 = -3/5
Plug in GH slope is -3/5
-5 - -2/ 4 - -1 = -3/5 = -3/5
The lines EF and GH are parallel lines because they have the same slopes.
Hope this helps ya!
Answer:
both outputs are x so f(x) and g(x) are inverses of each other
Step-by-step explanation:
Answer: 0.16$
Step-by-step explanation: You would do 1.99 divided by 12 because 12 equals to a dozen, 1.99 divided by 12 to get 0.16 cents.
