12 edges, 6 faces, and 7 vertices.
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
I say 12 edges because there are 12 meeting points, and an open shape.
6 faces because there are 6 highlighted points on what looks like an unfolded shape.
8 vertices because you add 2 to the number of edges and subtract by the number of faces, 6.

Step-by-step explanation:
The remote interior angles of ∠1 are ∠3 and ∠2
What are remote angles?The remote interior angles of a triangles are the two angles that are not adjacent to the exterior angle. The remote interior angles do not share the vertex of the exterior angle.
The angles inside the triangle that are opposite the exterior angle are referred to as remote interior angles. Remote interior angles, then, are those that do not share a triangle's vertex or corner with the outer angle.
Given data ,
Let the triangle be represented as ΔABC
Now , the measures of angles of ABC are
The measure of ∠A = ∠3
The measure of ∠B = ∠2
The measure of ∠C = ∠4
And , the exterior angle of the triangle is ∠1
So , angles inside the triangle that are opposite the exterior angle are referred to as remote interior angles.
The remote angles are ∠3 and ∠2

What are Linear Equations?An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution
On a graph, a linear equation forms a straight line. On a graph, a nonlinear equation produces an S-curve, a bell curve, or another nonlinear shape.
Given data ,
Let the linear function be represented as A
Now , the value of A is
y = 2x + 3
when the input values of the equation are x = { -2 , -1 , 0 , 1 , 2 , 3 }
The output values are
when x = -2
y = 2 ( -2 ) + 3
y = -1
On simplifying , we get
y = { -1 , 1 , 3 , 5 , 7 , 9 }

What is the slope of the line that passes through the points (-4, -2) and (-4, -22)? Write your answer in simplest form.
Answers
Answer:
Your answer is: Undefined
Use the slope formula to find the slope m .
Step-by-step explanation:
Hope this helped : )
The slope of the line that passes through the points (-4, -2) and (-4, -22) is an infinite slope.
The slope of a line can be found using the formula below.
m = y₂ - y₁ / x₂ - x₁Therefore,
x₁ = -4
x₂ = - 4
y₁ = -2
y₂ = -22
Therefore,
m = -22 - (-2) / - 4 - (-4)
m = -22 + 2 / - 4 + 4
m = 20 / 0
m = infinity
The slope is an infinite slope.

Step-by-step explanation:
There are 4 angles in quadrilateral which is equal to 360°. So...Add 100°, 110° and 80° and you will get 290°. Then, substract 290° from 360°. So you will get 70° which is Angle B. and then there's a straight line crossing the angle B. So divide with 2. You will get 35° which is equal to angle x because of the straight line.

Barry wants to open a checking account. He wants online services, and a debit card. He is looking at the following tables of fees from his employer's credit union, EECU, and a local bank, E-town Bank:
A 4-column table with 5 rows. Column 1 is labeled E E C U with entries monthly fee, non-sufficient funds fee, second copy of statement, network A T M usage, online services and debit cards. Column 2 is labeled Fee Table with entries 0 dollars, 28 dollars, 2 dollars, 2 transactions per month free after that 2 dollars each, free. Column 3 is labeled E-town Bank with entries monthly fee, non-sufficient funds fee, replacement statement copy, Network A T M usages, online services and debit cards. Column 4 is labeled Brief schedule of common fees with entries 2 dollars and 50 cents, 30 dollars, 5 dollars, 2 dollars each, free.
Based upon past experience, Barry expects no overdrafts. He expects no 2nd copies of statements. Barry estimates that he will use network ATMs about 5 times a month with either bank. Barry decides in the end to choose EECU. Assuming that both banks provide the necessary services equally well, and based upon the tables of fees given above, how much can Barry reasonably expect to save annually by choosing EECU in this case over E-town bank?
