Alternate Interior Angles Theorem

Vertical Angles Theorem
Definition Corresponding Angles.
The statement “Angle 2 is congruent to angle 4" is justified by the Vertical Angles Theorem. Option C is correct.
A mathematical proposition or assertion that has been proven to be true is known as a theorem.
According to this theorem, when two straight lines cross, they create two sets of linear pairs with matching angles. The adjacent angles created by the junction of these two lines are likewise said to be supplementary, or equivalent to 180 degrees.
It is given that,
∠2=∠4
From the diagram, it is observed that two straight lines cross, and they create two sets of linear pairs with matching angles as a result of the Vertical Angles Theorem angle 2 is congruent to angle 4.
Thus, the statement “Angle 2 is congruent to angle 4" is justified by the Vertical Angles Theorem. Option C is correct.

Solve for p. 3/5(p - 3) = -4
Answer:
p = 3.6666(repeating)
Step-by-step explanation:
3/5(p-3)=-4
We simplify the equation to the form, which is simple to understand
3/5(p-3)=-4
Simplifying:
+ 0.6*(p-3)=-4
Reorder the terms in parentheses
+( + 0.6p-1.8)=-4
Remove unnecessary parentheses
+ 0.6p-1.8=-4
We move all terms containing p to the left and all other terms to the right.
+ 0.6p=-4+1.8
We simplify left and right side of the equation.
+ 0.6p=-2.2
We divide both sides of the equation by 0.6 to get p.
p=-3.66666666667
What is the Desmos Graphing App for Algebra and how do you use it. Is it a computer thing or do you download it on your phone?
Answer:
see below
Step-by-step explanation:
The Desmos graphing utility is available as an app for phone or tablet from the app stores for Android and Apple devices. It is available from the desmos web site by clicking on "Graphing Calculator" on the home page.
Attached is a screen-shot of the web version. Help can be found under the (?) button at upper right. I found the help to be useful when first starting or when trying to do something I haven't done before.
You can create an account, if you like, but that is not necessary to obtain all of the basic functionality.
A link for sharing a graph will be generated by clicking on the icon to its left. Graphs can also be saved for later reference, if you have an account. The link to a graph will work whether you have an account or not.
__
There are other desmos tools available, too, for general calculation, geometrical construction, and matrix manipulation. (I have not yet used those.)
_____
Desmos likes to use x and y for the independent and dependent variables, respectively. You can define something like h(t) = 5t+1 and it will graph it as though it were y=5x+1. When you click on an equation or graph, points of intersection with other graphs or with the axes will be highlighted. Clicking on those highlights will give their coordinates.
Equations don't need to be of the "y=" form. For example, you can use x^2+y^2=1 to make a unit circle. The usual math symbols work for keyboard input (* for multiplication; / for division; ^ for exponents). The tab or arrow keys move out of denominator or exponent fields. To make more complicated exponents, parentheses help.
There's so much more it can do. It is worthwhile to visit the on-line tutorial information.
estimate 0.047512968 to the nearest hundredth express your answer as a single digit times a power of 10
Answer:
Estimate: 0.05, Scientific Notation: 5*10^-2
Step-by-step explanation:
Using the rules of rounding, we get 0.05. Next, all we do is move the decimal place to the right, and count the amount of times we move it to the left, 2, so the exponent is -2
how can i reduce -8/-3
Answer: there are really too many options...
Step-by-step explanation:
If you just want to keep it in simplest fraction form, the negatives cancel, giving you 8/3
But if you want to make it a mixed number, the negatives still cancel and since three goes into eight twice, with two leftover, you get 2 2/3
But if you want to make it a decimal, eight divided by three gives you 2.6666 repeating

You bought 4 pizzas and paid $7.00 each and cut the pizza into 8 equal slices. You
then sell the slices for $1.75 each. How many pieces would you have to sell to to pay
for the original cost of the 4 pizzas?
Answer:
You would have to sell
16 slices to pay for the
original price of the 4
pizzas
Step-by-step explanation:
$7.00 a box so you would have to multiply to get to
full price. $7.00x4=$28.00 The full price is $28.00.
If you are selling the slices for $1.75 each you would
also have to divide to know how many slices to sell
to get back to $28.00. 28.00÷1.75=16. So you would
have to sell 16 slices to get back to the full price.
Hope this helps.
Have a nice day :)

Find the volume of a right circular cone that has a height of 9.7 ft and a base with a
radius of 7.6 ft. Round your answer to the nearest tenth of a cubic foot.
Answer:
1/3*9.7*Pi*7.6^2 ft^3 and then round to nearest tenth
Step-by-step explanation:
The trick is knowing that the volume of the cone is exactly 1/3 of the volume of the cylinder with the same radius & height. This relation can be derived using integrals.

Answer:
[tex]r=-3/5=-0.6[/tex]
Step-by-step explanation:
We have the equation:
[tex]6^{-3r}=6^{2r+3}[/tex]
Since their bases are the same, the exponents must be equivalent. So:
[tex]-3r=2r+3[/tex]
Solve for r, subtract 2r from both sides:
[tex]-5r=3[/tex]
Divide both sides by -5:
[tex]r=-3/5=-0.6[/tex]
So, the value of r is -3/5.
And we're done!

Find the sum of the first 50 positive even integers.
The sum of the first 50 positive integers is 2550.
What is the sum of n even numbers?The sum of the n positive even integers is given by the formula below:-
S = n ( n + 1 )
n = number of the digits.
The sum of the 50 even positive integers will be calculated as:-
S = n ( n + 1 )
S = 50 ( 50 + 1 )
S = 2550
Therefore, the sum of the first 50 positive integers is 2550.

Write the equation of a line that passes through the points (−3, 7) and (3, 3)
y=−2/3x+5
y=2/3x+1
y=−2/3x+9
y=2/3x+9
Step-by-step explanation:
You can write an equation of a line conveniently by point-slope form. It's in the form of [tex]y -a = m(x -b)[/tex] where [tex](b,a)[/tex] is the coordinates of a point that's on the line and [tex]m[/tex] is the slope of the line.
Now choose a point (It doesn't really matter which one) and plug that in the equation. I'll choose [tex](-3,7)[/tex] where [tex]a = 7[/tex] and [tex]b = -3[/tex]
[tex]y -a = m(x -b) \\ y -7 = m(x -(-3)) \\ y -7 = m(x +3)[/tex]
The next thing we have to do now is finding the slope, [tex]m[/tex], where it's equal to [tex]\frac{y_{2} -y_{1}}{x_{2} -x_{1}}\\[/tex]. I'll make [tex](-3,7)[/tex] point 1 and [tex](3,3)[/tex] point 2.
[tex]m = \frac{3 - 7}{3 -(-3)} \\ m = \frac{3 - 7}{3 +3} \\ m = \frac{-4}{6} \\ m = -\frac{2}{3}[/tex]
Now let's plug that to our equation.
[tex]y -7 = m(x +3) \\ y -7 = -\frac{2}{3}(x +3)[/tex]
Now we have the equation but out of all the choices it seemed that all of them are in slope-intercept form all you have to do now is make our equation rewrite it in slope-intercept form.
[tex]y -7 = -\frac{2}{3}(x +3)\\ y -7 = -\frac{2}{3}x -\frac{2}{3}(3) \\ y - 7 = -\frac{2}{3}x -2\\ y = -\frac{2}{3}x +5[/tex]
Answer:[tex]y = -\frac{2}{3}x +5\\[/tex] is your equation.

profit per shirt sold
shirts: 5 10 15
profit: $7.50 $15.00 22.50
Answer: 1.5
Step-by-step explanation:
7.50/5 = 1.5
15/10 = 1.5
22.50/15 = 1.5
Answer:
$1.50
Step-by-step explanation:
To find the unit rate, we can divide the number of shirts to the profit that was made to find the unit cost per shirt.
7.50 / 5 = $1.50
15 / 10 = $1.50
22.50 / 15 = $1.50
