An analyst came up with the following relationships for a problem in his company. Which relationships are valid for a linear program, and which are not? Explain why or why not for each. Max 4x + 3 XY
s. t. 2x + Y<50
X-4Y >6
1.5 X2 + 6Y > 21
- X + Y = 5
5X +3underroot7 380
X, Y>0

- X + Y = 5  

Step-by-step explanation:

Linear function is:

y= mx+b or ax+bx+c= 0

Only option from the listed matching the above condition:

Max 4x + 3 XY  - not a linear function

s. t. 2x + Y<50  - inequality

X-4Y >6  - inequality

1.5 X2 + 6Y > 21  - inequality, quadratic

- X + Y = 5  - yes

5X +3underroot7 380  -  not a linear function

X, Y>0

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

41*67/2=1373.5
