A grader mills asphalt and finds the average number of feet milled over a period of 3 days. The expression 3(3x−9)+(5x+12)+x represents the situation.
Which statement is true?
The long mill section is 9 feet more than the medium mill section, and the medium mill section is 9 feet less than three times the short mill section.
The long mill section is 9 feet more than the medium mill section, and the medium mill section is 9 feet more than three times the short mill section.
The long mill section is 12 more than five times the medium mill section, and the short mill section is 9 feet less than three times the medium mill section.
The long mill section is 12 less than five times the medium mill section, and the short mill section is 9 feet less than three times the medium mill section.
A packaging company receives 2,730 packages. A package handler can scan 420 packages per hour for shipment.
If 0≤t≤6.5 , which function, f(h) , represents the number of packages that still need to be scanned after h hours? (a)
f(h)=2730−420h
f(h)=2370+420h
f(h)=2730(h+420)
f(h)=2730(h−420)

The graph is a linear function.
The y-intercept is (300, 0).
The y-intercept is (0, 300).
The graph is a non-linear funtcion.
An item is dropped from the center of a 110-foot suspension bridge. The item hits the ground below after 10 seconds. The table models the path of the dropped item.
Based on the table, which inequality best represents the range of the function for the height of the object?
y≤110
y≥10
0≤y≤10
0≤y≤110
A gamer analyzes data of the total points earned and the amount of time, minutes, the video gamer played the video game.
The linear model s=8m+7500 represents the average score, s , a professional gamer earns based on the number of minutes, m , the gamer spends practicing each day. What is the meaning of the slope in this linear model?
For each minute spent practicing each day, the gamer will lose 8 points during the video game.
For each minute spent practicing each day, the gamer will lose 7,500 points during the video game.
For each minute spent practicing each day, the gamer will earn 7,500 points during the video game.
For each minute spent practicing each day, the gamer will earn 8 points during the video game.
A gamer analyzes data of the total points earned and the amount of time, minutes, the video gamer played the video game.
The linear model, y=−254t+11.8 , represents the gamer's average error rate, y , of a video game based on, t , hours spent practicing each day.
Which statement is true?
The value −254 is the slope of the linear model, and it represents the error rate for 2 hours of practice each day.
The value −254 is the slope of the linear model, and it represents the error rate for 2.5 hours of practice each day.
The value 11.8 is the y-intercept of the linear model, and it represents the error rate for 0 hours of practice each day.
The value 11.8 is the y-intercept of the linear model, and it represents the error rate for 1 hour of practice each day.
