Answer:
Step-by-step explanation:
1) the triangle is right, so we can use the Pythagorean theorem
x^2 + 24^2 = (16+x)^2
x^2 + 576 = x^2 + 256 + 32x
32x = 320
x = 10
2) the two segment are congruent, so
7x - 13 = 9x - 23
2x = 10
x = 5
We have f(x) = 0;
Then x^2 - 1 - 2x - 2 = 0;
(x - 1)(x + 1) - 2(x + 1) = 0;
(x + 1)(x - 1 - 2) = 0;
(x + 1)(x - 3) = 0;
x + 1 = 0 or x - 3 = 0;
x = -1 or x = 3;
The zeroes of f are -1 and 3.

=================================
If you are asking to put that in y=mx+b form, it is:
2y=10x+8
y=5x+4
Do 2.72/8.5, it gives you .32 so that Is .32 cents per ounce. Now do 4.21/12.75 that gives you .33 cents per ounce. Now do 5.53/15.8 that gives you .35 cents per ounce, so in conclusion Ricky got the best deal.
