Answer:
could you show the triangle?
Get the b all alone on one side of the inequality. To do this, we can divide both sides by 5.
5b / 5 ≤ -15 / 5
b ≤ -3
So, that means b has to be less than or equal to -3.
In interval notation it would look like [-3, -∞)
In a set builder notation: {x | x ∈ R, x ≤ -3}
Which is read as the set of all x, such that, x is a member of the real numbers and x is less than or equal to -3.

Answer:
Step-by-step explanation:
She bought 18 ride tickets at $0.75 per ticket, so she spent 18 * $0.75 = $13.50 on rides. She spent a total of $33.50 for only admission and rides.
$33.50 - $13.50 = $20
Admission is $20.
(a) Let y represent total cost. Let x represent the number of ride tickets.
(b) y = 0.75x + 20
(c) The total cost is the cost of x ride tickets plus the admission.
x ride tickets cost 0.75x.
Admission is a fixed 20.
Adding the cost of ride tickets, 0.75x, to the admission cost, 20, gives you the total cost, y.
