< 4, - 7 >
Step-by-step explanation:
- w - z
= - < - 5, 3 > - < 1, 4 > ← multiply each component in w by - 1
= < 5, - 3 > - < 1, 4 > ← subtract corresponding components
= < 5 - 1, - 3 - 4 >
= < 4, - 7 >

Answer:
0.25
Step-by-step explanation:
formula is y2-y1 / x2-x1
-1.5 - (-3) / 0 - (-6)
-1.5 - (-3) = 1.5
0 - (-6) = 6
1.5 / 6 = 0.25
Solution:
Let x = the number of $70 seats sold
Let y = the number of $20 seats sold
x+y ≤ 20,000
70x+20y > 500,000
