Answer:

  • 0.5 hours

Step-by-step explanation:

Let the x be the number of hours after noon.

<u>We have the following equation:</u>

  • 14.83 + 0.12(x + 3) = 15.33 - 0.15x
  • 14.83 + 0.12x + 0.36 = 15.33 - 0.15x
  • 0.12x + 0.15x = 15.33 - 15.19
  • 0.27x = 0.14
  • x = 0.14/0.27
  • x ≈ 0.5

If y = 3x – 4 and the domain is { -3, -1, 4}, find the range. When the domain is -3, the range is ______. Show your work to find
Dafna1 [17]
<h2>Hello!</h2>

The answer is:

When the domain is -3, the range is -13.

<h2>Why?</h2>

To solve the problem, we need to remember that the domain is also known as the input of the function, and the range of the function is also known as the output of the function.

We are given the inputs and we are asked to calculate the output of the function at -3, so, evaluating -3 into the function, we have:

y=3x-4\\f(x)=3x-4\\f(-3)=3*(-3)-4=-9-4=-13\\

Hence, we have that when the domain is -3, the range is -13.

Have a nice day!

F(x) = x^2. What is g(x)?
mart [117]

Answer:

B

Step-by-step explanation:

The coordinates are (1, 9).

x = 1

y = 9

Put x as 1, and the output should be 9.

g(1) = ( 3 (1) )²

g(1) = (3)²

g(1) = 9
