Step-by-step explanation:
I thank it is B you have to add all the tickets and times that by the the amount of money
Answer:
Step-by-step explanation:
calculate midpoint of AA'
calculate midpoint of DD'
A(-5,1)
A'(-1,-3)
D(1,5)
D'(3,1)
then midpoint is
then find slope
then apply equation
substitute any point of the 2 midpoints to find b
then the equation is
First, you have to represent each given set by listing their elements. Observe:
• D = {x | x is a whole number}
D = <span>ℤ
</span>D = {..., – 3, – 2, – 1, 0, 1, 2, 3, ...}
• E = {x | x is a perfect square between 1 and 9}
("between" does not include the boundaries)
E = {x | x is a perfect square, 1 < x < 9}
E = {x | x = k², k ∈ ℕ and 1 < x < 9}
E = {2²}
E = {4}
• F = {x | x is an even number, 2 ≤ x < 9}
F = {2, 4, 6, 8}
So,
D ∩ F
= {..., – 3, – 2, – 1, 0, 1, 2, 3, ...} <span>∩ {2, 4, 6, 8}
</span>
= {2, 4, 6, 8} ≠ {4, 6}
Therefore, that statement is false.
I hope this helps. =)
