EXPLAIN how to do this plz. will mark brainliest. The graph shows the distance, y, in miles, of a moving motorboat from an island for a certain amount of time, x, in hours:

A graph titled Distance Vs. Time is shown with Time in hours labeled on x axis and Distance from Island in miles labeled on y axis. The scale on the x axis shows the numbers 1, 2, 3, 4, 5, 6, 7, and the scale on the y axis shows the numbers 0, 35, 70, 105, 140, 175, 210, 245, 280, 315. The graph shows a straight line joining the ordered pairs 0, 35, and 1, 105, and 2, 175, and 3, 245, and 4, 315.

What is the speed of the motorboat?

35 miles per hour
70 miles per hour
105 miles per hour
315 miles per hour

70 mph

Step-by-step explanation:

0, 35, and 1, 105, and 2, 175, and 3, 245, and 4, 315.

Every hour, the distance increases by 70 miles. 0-35, 1-105, 2-175, and so on. Therefore, the answer is 70

answer: the equation matches the regression

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
