Answer:

113

Step-by-step explanation:

To find the result of the equation, you just have to apply the given information that x = 3 and y = -5 into the equation:

31x + y2 - (xy)2

= 31 * 3 + -5 * 2 - (3*-5) * 2

= 93 + -10 + 15 * 2

= 93 -10  + 30

= 83 + 30

= 113

Hope this help you :3

A tortoise and a hare are competing in a race around a 1600-meter track. The arrogant hare decides to let the tortoise have a 95
umka2103 [35]

Answer:

A. t=4n+950

B. h=9.5n

C. d=9.5n-(4n+950)

D. The tortoise will finish first.

Step-by-step explanation:

To find the first two equations, we put the rate at which they are traveling in front of the n, and then add where they start. Since the tortoise gets a 950 meter head start, we add 950. The hare is starting at the start line so we don't need to add anything.

For answer c, we need to subtract the two equations from each other to figure out when they would pass each other. d=(equation h)-(equation t).

For the final answer, all you need to do is plug the first two equations into a graph, and then find where each line is at the point of y 1,600. (To make the graphs I replaced the n with x and the t and h with y.) Using this, we are able to see who got there first, which was the tortoise.
