1. Unit cost
18/3 = 6
2. When x = 1
In the graph I believe (1, 8)
Unit cost as 8
3. At Manglo since the unit cost is lower
4. 54/9 = 6
Noah runs 6 miles per day
Noah would win (5, 30)
Greta wins (5,45)
Greta wins more miles
Answer:
no
when you enter the point into the equation and solve, it does not work
Answer:
500
Step-by-step explanation:
brainliest pls
Y = mx + b
slope(m) = -3/4
(-2,5)...x = -2 and y = 5
now sub and find b, the y int
5 = -3/4(-2) + b
5 = 3/2 + b
5 - 3/2 = b
10/2 - 3/2 = b
7/2 = b
so ur equation is " y = -3/4x + 7/2....or 3x + 4y = 14
now it is just a matter of subbing in ur answer choices to see which ones work.
3x + 4y = 14...subbing in (6,-1)
3(6) + 4(-1) = 14
18 - 4 = 14
14 = 14 (correct).....so (6,-1) is a point on ur line <==
-10 - (-6) is like -10 +(-6).
The answer is -4 :)
