The price now is (80/100)x70 = (5600/100) = $56;
The slope of the line is the negative 4/3 and y-intercept will be the negative 1.
The correct equation is given below.
−4x − 3y = 3
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
The equation of the line will be
−4x − 3y = 3
Then the equation of a line can be written as
4x + 3y = −3
3y = −4x − 3
y = −(4/3)x − 1
Then the slope of the line is the negative 4/3 and y-intercept will be the negative 1.
The graph is given below.

19/8 is the improper fraction of 2 3/8.
Answer:
4200
Step-by-step explanation:
Time taken by Lester 30 seconds
Time taken by Ralph = 35 seconds
Their rate :
Lester = 1/time taken = 1/30
Ralph = 1/ time taken = 1/35
Combined rate:
1/30 + 1/35 = (35 + 30) / 1050 = 65 / 1050 = 0.0619047 per boot
Time taken = number of boots / combined rate per boot
Time taken = 260 / 0.0619047
Time taken = 4200 seconds
