Answer: B
Step-by-step explanation: A function is a relation in which each input value is paired to exactly one output value.
Technically, if you had the same input value twice and the same output value corresponded to each of those, it would still be a function because you are just repeating what you have twice.
However, most teachers want to think of it as each input value must have exactly one corresponding value to be a function.
Answer:2 hours 15 mins = 2 1/4 hours
2 1/4 hours = 25 miles
1 hour = 25 ÷ 2 1/4 = 25 ÷ 9/4 = 25 x 4/9 = 11.1 miles
Answer: 11.1 mph
Step-by-step explanation:
(√3 + 1)/8 the answer to the question
Answer:
60 mph
Step-by-step explanation:
(R-10)*3 + R*3 = 330
R=60
Answer:
B, C, F
Step-by-step explanation:
Given:

Subtract the second equation from the first equation:

Option B "The x coordinate of the solution is 9" is ture
Substitute it into the first equation:

Option F "The y coordinate of the solution is -8" is true.
Point (9,-8) is in the IV quadrant, so option C is true.
