Answer:
Step-by-step explanation:
4 and a half
Answer: 12a.) slope is 125, y-intercept is 50 (started at 50 ft)
12b.) f(3) = 425 feet
12c.) 3.6 hours
Step-by-step explanation:
12a.) The slope equation is y = mx+b, where m is the slope, and b is the y intercept.
12b.) to find f(3) you could either plug it into the equation given (125x+50) or pretend there is a vertical line at 3 on the x axis, and where it crosses the line given would be the answer.
12c.) He is climbing a 500 ft cliff, and according to the graph, it takes him 3.6 hours to do it. Another way to find this answer would be to find f(3.6), which is indeed 500 ft.
Hope this helps!
Answer:
-25+15u
Step-by-step explanation:
all you need to do is distribute the 5 to everything in the parenthesis!
Answer:
(0,1)(1,4)
Step-by-step explanation:
Put in any value of x to find y, then you have a coordinate, then plot it
lets say i pick 0 for x
y = 3(0) + 1
y = 1
(0,1)
lets say i also pick 1 for x
y = 3(1)+1
y = 4
You need atleast two points to plot a line, these are two points.
