If y - 1 = 4x, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
| © {(1,,8). (3. 12)
© {(4.1), (8, 2), (12. 3)
© {(0, 1), (1,.9)
{(1.0). (5. 1). (9.2)

Option C

{(0, 1), (1, 5), (2, 9)} represents possible inputs and outputs of the function

Solution:

Given function is:

y -1 = 4x

y = 4x + 1

To find the set which represents possible inputs and outputs of the function. Let's check all the options

Let us use the ordered pair (1, 4)

Substitute (x, y) = (1, 4) in given function

4 = 4(1) + 1

4 = 4 + 1

Thus this set is not the required set

Let us use the ordered pair (4, 1)

Substitute (x, y) = (4, 1) in given function

1 = 4(4) + 1

1 = 16 + 1

Thus this set is not the required set

Let us use the ordered pair (0, 1)

Substitute (x, y) = (0, 1) in given function

1 = 4(0) + 1

1 = 1

Thus this set is the required set represents possible inputs and outputs of the function.

Let us use the ordered pair (1, 0)

Substitute (x, y) = (1, 0) in given function

0 = 4(1) + 1

0 = 4 + 1

Thus this set is not the required set

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

she would want to sell 10 full-year subscriptions and at least 9 half-year subscriptions to get a total of at least $300.
