You can simply the above equation
1. 2x<7 = x<3.5 which means in order to satisfy the above notation the value of x has to be less that 3.5
2. -2x<7 = x<-3.5 it means in order to satisfy this notation the value of x has to be more than 3.5 in magnitude having - sign ..

When solving inequalities, dividing by a negative number requires you to fliip the sign.

So to solve 2x < 7 you simply divide by 2

x < 7/2

However with -2x < 7, you have to flip the sign

x > -7/2

Which value satisfies the inequality 3x+10-2x<-4x+45

anygoal [31]

First to answer

Answer:

x<7

Step By Step Answering:

Step 1: Simplify both sides of the inequality.

x+10<−4x+45

Step 2: Add 4x to both sides.

x+10+4x<−4x+45+4x

5x+10<45

Step 3: Subtract 10 from both sides.

5x+10−10<45−10

5x<35

Step 4: Divide both sides by 5.

5x/5<35/5

x<7

<h3>What is a graph?</h3>

A graph is a way to represent a lot of data in such a visual format that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.

The graph for the given question is attached below.

As it can be seen that the y-axis shown the distance between Eli's location and his home, since the distance is starting to decrease when the time is 120 seconds, therefore, it can be concluded that Eli rode his bicycle home from the library.

Hence, the correct option is C.
