B^-2/ab^-3 = b^-2/b^-3 x 1/a = b^[-2-(-3)] x 1/a = b x 1/a = b/a
Answer:
Bruce's tile covers up more space.
Step-by-step explanation:
So as we know, Bruce covers up around 1/4 of square feet and to find felicia's function we have to used the data we already have. For example, x=6 tiles, y=1 sq ft and x=12 tiles, y=2 sq ft, then we set y=kx which then we can find the value of k, 1=6k, k=1/6 then y=1/6. We then test the function with x=12 and x=18, y=1/6 12=2 and y=1/6 18=3. When the function is complete, we see that Bruce's tiles cover up more space because 1/4>1/6.
