Answer: The cost of the wallet is $60.
Step-by-step explanation: Mr. Wong spent a total of $176 on a jacket, a belt, and a wallet.
The wallet was $31 more expensive than the belt, and the jacket's price was three times that of the belt.
We need to determine the wallet's price.
Let x, y, and z denote the costs of the jacket, belt, and wallet, respectively.
Thus, based on the information given, we derive
Substituting the values of z and x from equations (ii) and (iii) into equation (i) yields
From equation (ii), we determine
Consequently, the wallet's price is $60.

Answer:
Therefore, the data is best represented by:
Step-by-step explanation:
We have a table indicating the estimated lines of code produced by computer programmers per hour when x individuals are engaged.
The question asks which model accurately reflects this data.
To determine this, we will substitute the values of x into each function to see which one accurately produces the corresponding y (f(x)) values provided in the table:
We are presented with four functions, which are:
A)
B)
C)
D)
We'll create a table displaying these values at various x levels.
x A B C D
2 66.66 49.3 52.5 50
4 94.57 71.44 106.3 104
6 134.14 103.57 160.1 158
8 190.27 150.14 213.9 212
10 269.91 217.64 267.7 266
12 382.85 315.5 321.5 320.
Thus, the function that suitably represents the data is:
Option C.
y=26.9x-1.3
Answer: x1 = 251/26, x2 = -111/26

Greetings!
As illustrated in the diagram, the point you seek is where the two lines intersect.
This intersection point is found by solving the system of linear equations (both equations must be satisfied by the point):
You can approach solving it using the substitution method:
Then substitute x1 into equation 2 to resolve x2:
After which, utilize the x2 value to establish x1:
