The figure shows the depths of a submarine. a. Find the vertical distance traveled by the submarine. Write your answer as a decimal.

The vertical distance is
feet.

Question 2
b. Find the mean hourly vertical distance traveled by the submarine. Write your answer as a decimal.

The mean hourly distance is
feet per hour.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

step-by-step explanation:

answer:   y=2x-3
