Because the 7 is used more than once.
1/3x let’s us the slope of the line is going up one and over three between each point. The +3 lets us know that the line will be located three points above the origin aka the middle/0,0 of the graph. Continuing this pattern will give you a positive linear line. The equation doesn’t make it so the line curves
Using the substitution method to solve the linear system the value of x and y is 1 and 2 respectively.
<h3>What is the linear system?</h3>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width.
Given
The equations are shown below.
y = 5 - 3x .....1
5x - 4y = -3 .....2
Substitute equation 1 in equation 2. Then

Then substitute the value of x in equation 1.

Thus, the value of x and y is 1 and 2 respectively.

Answer: C. decreased . . . increase.
As technology is advancing it requires less time and effort to do almost anything. So for tranportation as well i think it will take less time to do it. Thus logically people would want to trade more because the transport goods take less time. I guess?
(3w+6)-(2w+4)= w+2
Hope this helps
