Let x^2+50=0
solve for x first.
x^2=-50
x=+-√-50
Write that as a complex number
x=+-√50i
x=√50i or x=-√50i
Hope I helped :)
Answer:
My answer for the table is the following: 6, 18, 6, 60,000. For the long answer, I would say something along the lines of "All of the number in miles are 3 times the number in leagues. The number of leagues is 1/3 of the miles.
Step-by-step explanation:
For the table:
First step:
Find a pattern, in this case, it's that the miles are 3x the amount of leagues.
Second step:
If the miles are empty, simply mupilty by 3 for each. If the leagues are empty, divide by three.
For the short response:
I'm assuming it wants you to be able to recognize patterns (what numbers have in common). In this problem, you know that the miles are 3 times the amount of leagues because of the first set of numbers. The first set of numbers always helps you notice the pattern, so pay attention to those. This called the unite rate.
I hope this is correct and clear, this is my first answer.
30+0.25x=59.5
0.25x=59.5-30
x=29.5/0.25
x=118 messages
Answer:
3x+7
Step-by-step explanation:
x+5+2x+2
=(x+2x)+(5+2)
=3x+7
Answer:
They provide you with a graph that already has all the numbers and there is a data table. The data table lists all the numbers you have to plot onto the graph.
How to graph: The first number is 27, which is the vehicle weight in hundreds of lbs. On the graph, you can see that on the x-axis, it says weight (in hundreds of lbs). So first, look at the x-axis numbers and find somewhere between 25 and 30 and try to estimate where 27 would be.
Now look at the city MPG value that corresponds to 27, the weight value. It is 25. That's perfect because it is exactly the intervals the graph is in. So find 25 on the y-axis since the y-axis represents the city MPG. Now draw a straight line from the 25 on the y axis to the right. Then, draw a line from the 27 on the x axis straight up and where the two meet is the first point. Obviously, you don't need to make it that complicated if you don't need all the extra steps to understand but it is just in case you don't know how to graph the points.
Repeat for the rest of the points (make sure you use the correct corresponding points). Good luck on your test!
