Step-by-step explanation:
One supplementary angle is 15 degrees less than twice the other. Find the measure of the two supplementary angles.
Hey there!
To find our answer, we need to set up a system of equations. Remember, supplementary angles equal 180 degrees when combined. We will call one of our angles A and the other one B. Let's set it up below! :)
A=2B-15 (one angle is 15 degrees less than twice the other)
A+B=180
We need to find one of our variables. To do this, we only put one variable in the equation. But how, there are two variables in both equations! Well, as you can see, we see the A is equal to 2B-15, so we can take 2B-15 and put it into the second equation in place of A because it is equal to A, and then we will only have Bs and we can solve for it. This method is known as solving systems of equations with substitution.
Let's solve with substitution!
2B-15+B=180
3B-15=180 We combine our Bs.
3B=195 We add 15 to both sides.
B= 65 We divide both sides by three.
Now, we need to find what A is, but this will be really easy to do! If you remember, our angles are supplementary, so when you combine them, we will get 180, as you can see in our second equation in our first system of equations. So, we simply subtract 65 from 180.
180-65=115
Our two angles are 65° and 115°.
We can also check this with the original problem.
If you double 65, we have 130. Then, if we subtract 15, we have 115. Systems of equations are a pretty awesome way to figure this out!
I hope this helps! Have a great day!

Answer:

Step-by-step explanation:
5 12 13 triple
Answer:
r =5
Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 = c^2
The legs are r and 12
The hypotenuse is (8+r)
r^2 + 12^2 = (8+r)^2
r^2 + 144 = 64 + r^2 +16r
Subtract r^2 from each side
144 = 64 +16r
Subtract 64 from each side
144-64 = 16r
80 = 16r
Divide each side by 16
80/16 = 16r/16
5 =r
The graph represents the total costs for renting a bounce house or a dunk tank for a party. What is the meaning of (2, 20)? The rental cost for a dunk tanks starts at $20. The rental cost for a bounce house starts at $40. The costs for a dunk tank and bounce house are the same for 20 hours. The costs for a dunk tank and bounce house are the same for 2 hours.
Answer:
The costs for a dunk tank and bounce house are the same for 2 hours.
Step-by-step explanation:
The costs for a dunk tank and a bounce house are the same for 2 hours.
The meaning of the point (2, 20) on the graph is that the costs for a dunk tank and a bounce house are the same for 2 hours.
At this point, both the dunk tank and bounce house rentals cost $20.
It indicates the point of intersection between the two lines on the graph, where the costs for both options are equal.

The value of x and y angles on the given lines are x=35 degrees and y=125 degrees.
What is a straight line?A line is a collection of points which joins the two points on the surface.
How to calculate an angle?If we consider the angles which are linear pair, we found that
55 +y=180 because they are on a straight line.
From the figure wee found that x+55+90=180 because they are on a straight line.
solving the second equation we will get , x=180-145=35
solving the first equation we will get , y=180-55=125.
Hence the value of x angle is 35 degrees and the value of y angle is 125 degrees.

The diagram shows 3 vertices of a parallelogram.
Plot the 3 possible points for the 4th vertex.
Answer:
(-1, -1), (-3,5), (5, -3)
Step-by-step explanation:
(-1, -1) is the 4th vertex.
Which is the required vertex ?Let, 4th vertex is (x, y)
Given vertices of parallelogram are (-2. 2), (1, 1), (2, -2)
Here, (-2. 2) & (2, -2) are opposite vertices.
So, Midpoint of diagonals = [tex][(\frac{-2+2}{2}) ,(\frac{2-2}{2})][/tex] = (0, 0)
This is also midpoint of diagonal with vertices (1, 1) & (x, y)
So, (1+x)/2=0 ⇒ x = -1
& (1+y)/2=0 ⇒ y = -1
∴ 4th vertex is (-1, -1)

The range of which function includes -4?
O y= √x-5
O y= √x+5
O y= √x+5
O y=√x-5
Answer: A is the correct answer .
Start with the last two choices .
You have x+ 5 and × - 5 in the square root .
A square root can never be negative .
That means that the lowest value of y can have in the last two choices is 0 .
Now range doesn't include -4.
Now look at choice B .
sqrt (x) is at least 0.
Then you add 5 .
The range doesn't include -4.
Now look at choice A .
sqrt (x) is at lest 0 .
Now ,you subract 5 .
The lowest value y can have is -5 . That includes -4.
Choice A is the answer .

Answer: 8.3
Step-by-step explanation:
To find the variance, you want to find the mean of the data.
[tex]\frac{3+3+8+1+9+6}{6} =5[/tex]
Now that we have the mean, we find the difference between each data point and the mean.
3-5=-2
3-5=-2
8-5=3
1-5=-4
9-5=4
6-5=1
With the difference, you square each and find the average.
(-2)²=4
(-2)²=4
3²=9
(-4)²=16
4²=16
1²=1
[tex]\frac{4+4+9+16+16+1}{6} =\frac{25}{3}[/tex]
