Answer:
All real numbers / (-∞, ∞) / R
Step-by-step explanation:
The equasion provided is a linear equasion meaning it can be written in the y=ax+b format, where both a and b are real numbers. All linear eqasions have a range of all real numbers, you can write this using the three solutions provided.
You can solve this two ways, number one would be to put this in a graphing calculator and number two would be reducing the equasion to the y=ax+b format.
<h2>Method 1:</h2>
look at image provided. The app is PhotoMath.
<h2>Method 2:</h2>
Write the equasion:
y = -2x - 6x + 1
Collect like terms:
y = -8x + 1
This now proves that the equasion is linear becuase you can write it in the y=ax+b format. a being -8 and b being 1.
Answer:
x=6
Step-by-step explanation:
3x-8=10
+8 +8
3x=18
x=18/3
x=6
To find the length of the arc given the central angle, multiply (the fraction of the angle of the full circle, 360°, that the central angle, 120°, makes up)*(the total circumference of the circle). You're basically finding the fraction of the circumference that is covered by the central angle, if that makes any sense.
So the central angle makes up
the entire circle. You are given that the circumference of the circle is 18. Multiply the fraction of the full circle that the central angle makes up (
) by the circumference of the circle:
The length of your arc is 6.
Let me know if you're confused b/c my explanation isn't the greatest :) I'll try to explain it better if you don't understand.
Answer:
Yes, the sum of any two sides is greater than the third.
Step-by-step explanation:
To determine whether the provided sides are the sides of a triangle check if the sum of two sides is more than the third side.
The length provided are: 8.5, 13 and 19.1.
- Consider the sides 8.5 and 13:
The sum is:
This sum is greater than the third side 19.1
- Consider the sides 8.5 and 19.1:
The sum is:
This sum is greater than the third side 13
- Consider the sides 13 and 19.1:
The sum is:
This sum is greater than the third side 8.5
Thus, the sides 8.5, 13 and 19.1 are sides of a triangle.
