Final answer:
To predict y for y=9x^-1 when x=10, substitute the value of x into the equation to get y = 9(0.1) = 0.9.
Step-by-step explanation:
To predict y when x=10 for the function y=9x-1, you need to substitute the value of x into the equation and perform the calculation. Doing so, we use the reciprocal of 10 which is 0.1, and then multiply that by 9.
So, y = 9(10-1) = 9(0.1) = 0.9.
Therefore, when x=10, the predicted value of y is 0.9.
