One would rewrite this as: 73/(12-7)

mower and can mow the field in 75 minutes.
If Roni and Allie work together to mow the field, what part of the field would Roni mow?
A He would mow the bigger part of the field

1: Assuming this line is linear, the first thing to do is find the slope.
The slope formula is

, so in this case, it is

, which comes to

. Then, use your slope and one of the points given to write the point-slope formula of the linear equation, and then written in standard form:
y=

x-

.
2. Use the same process as in question 1 to find:
y=-7x+11
Answer:The first one and the thrid one
Step-by-step explanation:
The second one isn't a linear one because number 5 represents 3,1... and that number is down the y's line. That means it has to go down again but without decreasing, stopping the function to become a linear one and becoming a non constant one.
I hope I'm being helpful...
