Question

If y = 5x − 4, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
a {(0, −4), (2, 6), (4, 20)}
b {(0, −4), (2, 6), (4, 16)}
c {(0, 4), (2, 6), (4, 16)}
d {(0, 4), (2, −6), (4, 20)}

Answer 1

Step-by-step explanation:

b is the correct answer

b {(0, −4), (2, 6), (4, 16)}

thank you

Answer 2

Answer:

b)({(0,-4),(2,6),(4,16)}

Step-by-step explanation:

y=5x-4

If y=-4 then,

-4=5x-4

-5x=-4+4

-5x=0

x=0/-5

x=0

Now, if y=6 then,

6=5x-4

-5x=-4-6

-5x=-10

5x=10

X=10/5

x =2

If y=16

16=5x-4

-5x=-4-16

-5x=-20

5x=20

x=20/5

x=4

Hope it helps
