alec calculated the slope of line ac between points a and b. avis calculated the slope of line ac between points b and c. both alec and avis drew triangles, as shown below, to calculate the slopes:

a graph shows numbers from 0 to 18 on the x axis at increments of 2 and the numbers 0 to 6 on the y axis at increments of 1. a line ac is drawn that joins the ordered pairs 0, 0 and 18, 6.the ordered pair 6, 2 is labeled as b. a right triangle is drawn with ab as hypotenuse and height 2 units. another right triangle is drawn with bc as the hypotenuse and height 4 units.

which statement is correct about the slopes calculated by alec and avis if both calculated the slopes accurately?

both calculated the slope as 3.
both calculated the slope as 1 over 3.
alec calculated the slope as 1 over 3 and avis calculated it as 3.
alec calculated the slope as 3 and avis calculated it as1 over 3.

The base of a triangle exceeds the height by 9 inches. if the area is 180 square inches, find the length of the base and the height of the triangle.

Time (minutes) amount of water (gallons) practice 1. jin fills up a 510-gallon pool in the backyard for her children. she fills it with the garden hose at a rate of 17 gallons per minute. after it is filled, she lets it sit for 30 minutes in order to let the water temperature rise. the children then get in and have fun for an hour. the pool loses about 5 gallon of water each minute due to their splashing and playing. at the end of the hour, they tear the pool while getting out, which causes a leak the pool then begins to lose water at a rate of 2 gallons per minute. a. complete the table to show the amount of water in the pool after each minute. b. create a graph to model the problem situation. include when the pool will be empty. c. write a piecewise function that models this problem situation. explain your reasoning for each piece of the function. d. identify the x- and y-intercept. explain what they mean in terms of the problem situation, atamantha a cul 80 100 120 150 200 ning, inc
