2x+y=2 and y =-2x-1 how many solutions does this system have? (System of Equations)

Mathematics

Answer:

No solutions

Step-by-step explanation:

First you'll want to rewrite one equation so both can be in the same form:

2x+y=2 becomes y=-2x+2, I just subtracted 2x from both sides

Now you have y=-2x+2 and y=-2x-1. Just by looking at the two equations you can tell they share the same slope and the only thing different is the y-intercept. This system has 0 solutions because they are parallel lines; they will never meet or intersect.

Answer:

No Solutions

Step-by-step explanation:

I used a graphing tool to graph the two lines. When graph, the lines are parallel, and they do not intercept at any point. They have no solution.

The following data shows the number of music shows 20 students of a class watched in a month:
3241004551 [841]

Answer:

The 2nd one.

Step-by-step explanation:

First, put the numbers in order from least to greatest. This isn't required, but it makes it easier.

3 4 4 4 4 4 4 4 7 7 8 9 10 10 13 13 19 19 19 20

Then, for each range of shows watched (0-5, 6-11, etc.) from the graph, count how many numbers from the list fit into that range.

Use the process of elimination:

In 3 4 4 4 4 4 4 4 7 7 8 9 10 10 13 13 19 19 19 20, numbers from 0-5 show up 8 times, so you can rule out the last 2 graphs. Numbers 12-17 show up 2 times, so the first one is incorrect. That leaves you with the second histogram.
