The output of a function is 24 less than 9times the input
write an equation for the function described.
b) use your equation to find the input when the output is -10
Could someone help me?
Thanks!
y=9x-24
then, -10=9(x)-24 and solve for x
Sure, I can help you with that!
Let's define the input as "x" and the output as "y". According to the given information, the output is 24 less than 9 times the input.
We can express this relationship as an equation like this:
y = 9x - 24
Now, to find the input when the output is -10, we can substitute -10 for y in the equation and solve for x.
-10 = 9x - 24
To isolate x, we can add 24 to both sides of the equation:
-10 + 24 = 9x
14 = 9x
Finally, divide both sides of the equation by 9 to solve for x:
14/9 = x
So, when the output is -10, the input is approximately 1.556, or you can also express it as a fraction: x = 14/9.
I hope this helps! Let me know if you have any further questions.
