First find h(7) h(x) = 3x-14 h(7) = 3(7)-14 h(7) = 21-14 h(7) = 7 Then h-1 (h(7)) = h-1 (7) = then find h-1 of 7 by plugging 7 in for x. h-1 (x) = (x+14)/3 h-1 (7) = (7+14)/3 h-1 (7) = 21/3 h-1 (7) = 7 h-1 (h(7)) = h-1 (7) = 7. So when a function is composed with its inverse, you get a function that gives you back the same number for y that you ...

91= x^2+6x 0=x^2+6x-91 0=x^2+13x-7x-91 0=x(x+13)-7(x+13) 0=(x-7)(x+13) 0=(x-7) OR 0=(x+13) 7=x OR -13=x (negative width not possible) x=7 inches width and length is six more so 7+6=13 Answer is 7 and 13 are the length and width of the rectangle I …

Each time we subtract 1 fancy shirt, and add a plain shirt, we subtract a net cost of $13 (since -28+15 = -13) Then notice how 13 is a factor of 65 65 = 13*5 This tells us that we need to introduce 5 plain shirts The 7 fancy shirts will drop to 7-5 = 2 fancy shirts. ----- Another approach: x = number of fancy shirts y = number of plain shirts

However, the sequence 2, 3, 5, 7, 11 are the first five prime numbers. A prime number is a positive integer which has exactly 2 positive integer factore, one factor being 1 and the other factor is the positive number itself.
