Y= 3 -x (1)
3x + 4y = 1 (2)
Substitute (1) for y in (2)
3x + 4(3 - x) = 1
Expand, simplify and then solve for x
3x + 12 - 4x = 1
3x - 4x = 1 -12
-x = -11
x = 11
Answer: Yes
0.72 repeating as a fraction in simplest form is 9/11
R=4 because 20-4 = 16 and 4 times 4 = 16

40 students like tennis.
46 - 40 = 6 more students like baseball than tennis
Using linear functions, it is found that the number of electronics that you need to sell for a larger income in option A is x > 200,000.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Considering the <u>base salaries as the intercept and the commissions as the slope</u>, the functions are given by:
To produce a larger income in option A, it is needed that:
A(x) > B(x).
Hence:
10000 + 0.09x > 20000 + 0.04x
0.05x > 10000
x > 10000/0.05
x > 200,000
