Answer:
B = (7, 2)
Step-by-step explanation:
B = 2M -A
B = 2(3, 4) -(-1, 6) = (2·3-(-1), 2·4-6)
B = (7, 2)
_____
The expression for the other end point, B, comes from the equation for the midpoint.
M = (A +B)/2
2M = A + B . . . . . multiply by 2
2M -A = B . . . . . . subtract A to get an expression for B
612/6=102
check: 6x102=612
Hope this helped! :))
Answer: c. t > 82
Step-by-step explanation:
Let t represent the number of tickets that the committee would sell.
The dance committee of Pine Bluff Middle School earns $72 from a bake sale and will earn $4 for each ticket they sell to the Spring Fling dance. This means that the revenue that they would generate from selling x tickets is
72 + 4x
The dance will cost $400.
To make profit, revenue must be greater than cost. Therefore, the inequality to determine the number of tickets the committee could sell to have money left over after they pay for this year's dance is
72 + 4x > 400
4x > 400 - 72
4x > 428
x > 328/4
x > 82
