Which set of ordered pairs represents a function? \{(5, -2), (0, 3), (-4, 6), (0, 5)\}{(5,−2),(0,3),(−4,6),(0,5)} \{(5, 7), (5,
Arturiano [62]
Answer:
(-5, -9), (8, -4), (-4, -3), (4, -4)
a function does not have a repeating domain or x. hope this helps.
Answer:
D. 31
Step-by-step explanation:
First we need to find what the value of f(2) is, so we are going to substitute x for 2 in f():
f(2)=4(2)^3-10
= 4(8)-10
= 32-10
= 22
And then we substitute 22 for x in g()
g(22)= (3(22)-4)/2
= (66 -4)/2
= 62/2
= 31
Since there is 60 minutes in a hour you would multiply 20*3 to get the hour. Now since you multiplied the minutes by 3 you also multiply the amount of miles giving you 9 miles per hour
Answer:
a.
y= 40x +4000
x= 100 --> y= 40(100)+4000= 4000+4000=8000
x=200 --> y= 40(200)+4000= 6000+4000= 10000
x=300 --> y= 40(300)+4000= 12000+4000= 16000
(in $)
b.
y= 40x+4000
6200= 40x+4000
6200-4000= 40x
2200= 40x
2200/40= x
55= x
(in unit)
