Answer:
The answer is 14.
Step-by-step explanation:
4.50 + 2.00x ≤ 32.50
32.50 - 4.50 = 28
28 / 2.00 = 14
The total number of tickets he can buy is 14.
Answer:
domain is [1, ∞)
Step-by-step explanation:
On the coordinate grid, the graph of y=3√x-1 +3 is shown. It is a translation of y=3√x .
find the domain of graphed fuction, graphed function is a square root function
to find domain of square root function we always set the argument inside the square root >=0 and solve for x
x-1 ≥ 0
add 1 on both sides
x ≥ 1
domain is [1, ∞)
y = - 3(x + 1 )² + 2
the equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
here vertex = (- 1, 2), hence
y = a(x + 1)² + 2
to find a substitute (1, - 10) into the equation
- 10 = 4a + 2 ⇒ 4a = - 12 ⇒ a = - 3
y = - 3(x + 1)² + 2 ← in vertex form
