Answer: -1/21
Answer:

Step-by-step explanation:


When t = 0 the point on the graph is (0,36). Your equation is just a line and always has the same tangent line so your equation is the same s = 36 - t.
Answer:
11 2/3 pounds
Step-by-step explanation:
If a pack contain 1 2/3 pounds, 7 packs would contain :
1 2/3 x 7
× 7 = 35/3 = 11 2/3 pounds
You could just factor out the Trinomial and find the zeros of the equation,
x^2 - 2x -15 = (x - 5)(x + 3) = 0,
x - 5 = 0 and x + 3 = 0, so x = 5,-3 AKA answer choice C
