Lets say the number of adult tickets is x. This means the number of student tickets is 2x. So, 2x + x = 285, or 3x =285. The means x = 95. So the number of adult tickets sold is 95.
For this case, the first thing we must do is evaluate the function in each of the domain points.
We have then:
f (-1) = 2 (-1) + 1 = -2 + 1 = -1
f (0) = 2 (0) + 1 = 0 + 1 = 1
f (1) = 2 (1) + 1 = 2 + 1 = 3
f (2) = 2 (2) + 1 = 4 + 1 = 5
The range of the function will then be:
R = {-1, 1, 3, 5}
Answer:
The range of the function f (x) = 2x + 1 given the Domain D = {-1, 0, 1, 2} is:
R = {-1, 1, 3, 5}
He spent 560. Just multiply 70 with 8
Answer:
If it's a rectangle, then point D is (3,-1)
The area would be 7 x 3 = 21 units²

Associative property of addition: Changing grouping of addends doesn't change the sum.
Distributive property: Multiplying a sum by a number is the same as multiplying each addend by that number and then adding the two products.
Associative property of multiplication: Changing grouping of the factors doesn't change the products.
Commutative property of multiplication: Changing order of the factors doesn't change the products.
