When the input is x=0.3 , which of the following is the output of the function y=3x+6 ?(1 point)

The output of the function y=3x+6 when x=0.3 is:

y = 3(0.3) + 6
y = 0.9 + 6
y = 6.9

So, the correct answer is 6.9.

The value of the function y = 18x - 13 when x = -4 is:

y = 18(-4) - 13
y = -72 - 13
y = -85

So, the correct answer is -85.

Apologies for missing that instruction, the correct response based on the available options would be:

-12.5

Use the image to answer the question.

An illustration shows a coordinate plane with four quadrants. The x and y axes range from negative 6 to 6 in increments of 1. A semicircle is graphed on the plane. The semicircle passes through points plotted at coordinates left parenthesis 0 comma 6 right parenthesis, left parenthesis 6 comma 0 right parenthesis, and left parenthesis 0 comma negative 6 right parenthesis.

The graph described as a semicircle passing through points (0,6), (6,0), and (0,-6) is not a function. This can be confirmed by applying the vertical line test. Since there would be multiple y-values for an x-value, the relation fails the vertical line test, indicating that it is not a function.

Therefore, the correct response is:
"No, the given relation is not a function."

Which of the following is an ordered pair of the relation y=−23x+6?(1 point)

Responses

(1,4)
left parenthesis 1 comma 4 right parenthesis

(0,−23)
left parenthesis 0 comma negative Start Fraction 2 over 3 End Fraction right parenthesis

(3,4)
left parenthesis 3 comma 4 right parenthesis

(3,8)

To determine if an ordered pair is part of the relation y = -23x + 6, we can substitute the x-value into the equation and check if it yields the corresponding y-value.

Let's check the given options:

1. For (1,4):
y = -23(1) + 6
y = -23 + 6
y = -17
So, (1,4) does not match the equation.

2. For (0,-23):
y = -23(0) + 6
y = 0 + 6
y = 6
So, (0,-23) does not match the equation.

3. For (3,4):
y = -23(3) + 6
y = -69 + 6
y = -63
So, (3,4) does not match the equation.

4. For (3,8):
y = -23(3) + 6
y = -69 + 6
y = -63
So, (3,8) does not match the equation.

Therefore, none of the given ordered pairs are part of the relation y = -23x + 6.
