Find the output of the function y=−3x−7 when the input is −5
. (1 point)
The correct output is what?
To find the output of the function y = -3x - 7 when the input is -5, we need to substitute -5 for x in the equation and solve for y.
Substituting -5 for x in the equation, we get:
y = -3(-5) - 7
Multiplying -3 by -5, we have:
y = 15 - 7
Finally, performing the subtraction, we find:
y = 8
Therefore, the output of the function y = -3x - 7 when the input is -5 is 8.
