Using the equation y = 18x - 13, we substitute x = -4:
y = 18(-4) - 13 = -72 - 13 = -85.
Therefore, the value of the function y = 18x - 13 when x = -4 is -85.
bot gpt y = 1/8x - 13, we substitute x = -4:
Using the equation y = (1/8)x - 13, we substitute x = -4:
y = (1/8)(-4) - 13 = -1/2 - 13 = -13.5.
Therefore, the value of the function y = (1/8)x - 13 when x = -4 is -13.5.
To find the value of the function y = 18x - 13 when x = -4, you can substitute the value of x into the function and evaluate it.
Let's substitute x = -4 into the function:
y = 18(-4) - 13
Now, simplify the expression:
y = -72 - 13
y = -85
So, the value of the function y = 18x - 13 when x = -4 is -85.
