To find the output of the function y = -3x - 7 when the input is x = -5, substitute -5 for x in the equation and solve for y.
y = -3(-5) - 7
y = 15 - 7
y = 8
So when the input is -5, the output of the function y = -3x - 7 is 8.

Find the value of the function y=3x2−21 when x=4 .(1 point)
To find the value of the function y = 3x^2 - 21 when x = 4, substitute 4 for x in the equation and solve for y.
y = 3(4)^2 - 21
y = 3(16) - 21
y = 48 - 21
y = 27
So the value of the function y = 3x^2 - 21 when x = 4 is 27.
y = 3(4)^2 - 21
y = 3(16) - 21
y = 48 - 21
y = 27
So the value of the function y = 3x^2 - 21 when x = 4 is 27.

To find the output of the function y = 3x + 6 when the input is x = 0.3, substitute 0.3 for x in the equation and solve for y.
y = 3(0.3) + 6
y = 0.9 + 6
y = 6.9
So when the input is x = 0.3, the output of the function y = 3x + 6 is 6.9.
y = 3(0.3) + 6
y = 0.9 + 6
y = 6.9
So when the input is x = 0.3, the output of the function y = 3x + 6 is 6.9.

To find the value of the function y = 18x - 13 when x = -4, substitute -4 for x in the equation and solve for y:
y = 18(-4) - 13
y = -72 - 13
y = -85
So the value of the function y = 18x - 13 when x = -4 is -85. The provided responses do not include this value, so the correct value is -85.
y = 18(-4) - 13
y = -72 - 13
y = -85
So the value of the function y = 18x - 13 when x = -4 is -85. The provided responses do not include this value, so the correct value is -85.

Yes, I apologize for the confusion in my previous response. Let's go through the calculation again.
Given the function y = 18x - 13 and the value x = -4, let's find the value of y:
y = 18(-4) - 13
y = -72 - 13
y = -85
And yes, I'm certain that when x = -4, the value of the function y = 18x - 13 is indeed -85. None of the provided responses match this correct value. If there is a specific context or a set of given responses, please ensure that they are accurate or consider that the response of -85 might not have been included in the options you have.

To determine which of the given ordered pairs is a part of the relation y = -23x + 6, let's calculate the value of y for each provided x in the ordered pairs.
1. For the ordered pair (3, 8), with x = 3:
y = -23(3) + 6
y = -69 + 6
y = -63
(3, 8) does not satisfy the equation since y should be -63, not 8.
2. For the ordered pair (3, 4), with x = 3:
y = -23(3) + 6
y = -69 + 6
y = -63
(3, 4) does not satisfy the equation since y should be -63, not 4.
3. For the ordered pair (1, 4), with x = 1:
y = -23(1) + 6
y = -23 + 6
y = -17
(1, 4) does not satisfy the equation since y should be -17, not 4.
4. For the ordered pair (0,−23), with x = 0:
y = -23(0) + 6
y = 0 + 6
y = 6
(0,−23) does not satisfy the equation since y should be 6, not -23.

y = -23(3) + 6
y = -69 + 6
y = -63

Given the relation \( y = -\frac{2}{3}x + 6 \), let's determine which of the provided ordered pairs satisfies this relation:
1. For the ordered pair (3, 8), with \( x = 3 \):
\( y = -\frac{2}{3}(3) + 6 \)
\( y = -2 + 6 \)
\( y = 4 \)
The pair (3, 8) does not satisfy the equation since y should be 4 when \( x = 3 \), not 8.
2. For the ordered pair (3, 4), with \( x = 3 \):
\( y = -\frac{2}{3}(3) + 6 \)
\( y = -2 + 6 \)
\( y = 4 \)
The pair (3, 4) satisfies the equation.
3. For the ordered pair (1, 4), with \( x = 1 \):
\( y = -\frac{2}{3}(1) + 6 \)
\( y = -\frac{2}{3} + 6 \)
\( y = 6 - \frac{2}{3} \)
\( y = \frac{18}{3} - \frac{2}{3} \)
\( y = \frac{16}{3} \)
\( y = 5\frac{1}{3} \)
The pair (1, 4) does not satisfy the equation since y should be \( 5\frac{1}{3} \), not 4.
4. For the ordered pair (0, −2/3), with \( x = 0 \):
\( y = -\frac{2}{3}(0) + 6 \)
\( y = 0 + 6 \)
\( y = 6 \)
The pair (0, −2/3) does not satisfy the equation since y should be 6 when \( x = 0 \), not \( -\frac{2}{3} \).
Based on these calculations, the only pair that satisfies the equation y = \( -\frac{2}{3}x + 6 \) is (3, 4).
1. For the ordered pair (3, 8), with \( x = 3 \):
\( y = -\frac{2}{3}(3) + 6 \)
\( y = -2 + 6 \)
\( y = 4 \)
The pair (3, 8) does not satisfy the equation since y should be 4 when \( x = 3 \), not 8.
2. For the ordered pair (3, 4), with \( x = 3 \):
\( y = -\frac{2}{3}(3) + 6 \)
\( y = -2 + 6 \)
\( y = 4 \)
The pair (3, 4) satisfies the equation.
3. For the ordered pair (1, 4), with \( x = 1 \):
\( y = -\frac{2}{3}(1) + 6 \)
\( y = -\frac{2}{3} + 6 \)
\( y = 6 - \frac{2}{3} \)
\( y = \frac{18}{3} - \frac{2}{3} \)
\( y = \frac{16}{3} \)
\( y = 5\frac{1}{3} \)
The pair (1, 4) does not satisfy the equation since y should be \( 5\frac{1}{3} \), not 4.
4. For the ordered pair (0, −2/3), with \( x = 0 \):
\( y = -\frac{2}{3}(0) + 6 \)
\( y = 0 + 6 \)
\( y = 6 \)
The pair (0, −2/3) does not satisfy the equation since y should be 6 when \( x = 0 \), not \( -\frac{2}{3} \).
Based on these calculations, the only pair that satisfies the equation y = \( -\frac{2}{3}x + 6 \) is (3, 4).
