Which shows three ordered pairs that are all solutions of the equation y = x + 4?
svetoff [14.1K]
When x = 1, y = 1 + 4 = 5

When x = 3, y = 3 + 4 = 7
When x = 5, y = 5 + 4 = 9
When x = 7, y = 7 + 4 = 11

Therefore, the correct answer is option D.

lawyer [7]

Functions can be used to model real life situations.

The hose is 3.2 feet above the ground, at a horizontal distance of 4 fee

The function is given as:

f(x) =-0.3x^2 + 2x

At a horizontal distance of 4 feet, the value of x is 4

i.e. x = 4

Substitute 4 for x in f(x).

So, we have:

f(4) =-0.3(4)^2 + 2(4)

Evaluate the exponent

f(4) =-0.3(16) + 2(4)

Open both brackets

f(4) =-4.8 + 8

Add -4.8 and 8

f(4) =3.2

Hence, the hose is 3.2 feet above the ground
