<h3>Answer:</h3>
The Second one {(-8,-7), (4,-2), (2,9), (-8,8)}
<h3 /><h3>
Step-by-step explanation:</h3>
A function only gives ONE out put for a given value. But the second set has two outputs if we input -8, it gives you -7 and 8 so this must not be a function.
Answer:
0.1
Step-by-step explanation:
Take paranthesis away.
5.6-3.2-2.3
subtract 3.2 from 5.6
2.4-2.3=0.1

Answer:
The amount of change she received is
$16.1
Step-by-step explanation:
1.what is asked in the problem?
We are to find how much change she received
what are the given facts?
She bought:
notebook which cost 23.75; a set of colored pens which cost 36.20 and a liquid eraser which cost 23.95
She gave the cashier $100
2.what operation to be used to solve the problem ?
Addition and Subtraction operation
3.solve
= $100 - ($23.75 + $36.20 + $23.95)
= $100 - $83.9
= $16.1
The amount of change she received is
$16.1
<h2>
Speed of plane = 1110 kmph</h2><h2>
Speed of wind = 150 kmph</h2>
Step-by-step explanation:
Let the speed of plane be p and speed of wind be w.
Flying against the wind, an airplane travels 5760 kilometers in 6 hours.
Here
Speed = (p-w) kmph
Time = 6 hours
Distance = 5760 kmph
Distance = Speed x Time
5760 = (p-w) x 6
p-w = 960 -----eqn 1
Flying with the wind, the same plane travels 6300 kilometers in 5 hours.
Here
Speed = (p+w) kmph
Time = 5 hours
Distance = 6300 kmph
Distance = Speed x Time
6300 = (p+w) x 5
p+w = 1260 -----eqn 2
eqn 1 + eqn 2
p-w + p +w = 960 + 1260
2p = 2220
p = 1110 kmph
Substituting in eqn 2
1110 + w = 1260
w = 150 kmph
Speed of plane = 1110 kmph
Speed of wind = 150 kmph
