Answer:
<h2>First graph.</h2>
Step-by-step explanation:
The given function is
![y=\sqrt[3]{x-3}](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7Bx-3%7D)
Observe that the three units are a translation in horizontal direction. Specifically, indicates a 3 units translation rightwards, because negative units added to
means rightward movement. So, we need to a curve moved 3 units to the right.
Notice that the first graph is the only one moved three units rightwards. We deduct this because the function showed by the first graph is the only which crosses x=3.
Therefore, the right answer is the first graph.
Then 1 white, then 3 blue then 1 white
Answer:
See below.
Step-by-step explanation:
Let “x” be a coach ticket.
Let “y” be a first class ticket.
Let’s set up a system of equations.
120x + 990y = 3210
x + y = 5
120x = 3210 - 990y
x = 26.75 - 8.25y
26.75 - 8.25y + y = 5
- 7.25y = -21.75
y = 3
120x + 990 * 3 = 3210
120x = 240
x = 2
She bought 2 coach tickets and 3 first class tickets.
