A graph is shown below:
Charra [1.4K]

Answer:

The correct answer is actually B. x - 3y < 5

Step-by-step explanation:

Because you must convert the equation to y-intercept form first.

Which makes it y = 1/3x - 1.6

So y = 1.6 and using the slope of 1/3x you can find that x = 5

A computer manufacturer shipped a total of 50 machines to its two warehouses, one in west and one in east. It cost 20$ per machi
Natalka [10]
E + w = 50.....w = 50 - e
25e + 20w = 1090

25e + 20(50 - e) = 1090
25e + 1000 - 20e = 1090
25e - 20e = 1090 - 1000
5e = 90
e = 90/5
e = 18 <=== the east got 18

w = 50 - e
w = 50 - 18
w = 32 <=== the west got 32
