Answers
Answer:
1. D
"n" represents the figure. For example, the equation for figure 3 would be [tex]\frac{3(3+1)}{2}[/tex] which is equal to 6 (the amount of blocks in the figure).
2. D
In the sample equations, the 9 represents figure 9. There are consistently 3 blocks in each row with an additional block at the top of the figures. So, the equation for figure 4 would be 1+(3x4) which is equal to 13. Therefore, the equation for figure 9 would be 1+(3x9).
3. A
P represents the perimeter and the n represents the figure number (like in question 1). The correct equation for the pattern would be P=4n+8. To check it, we can plug the numbers from figure 2. The equation would look like this: 16=4(2)+8
4. B
To find the answer to this problem, we just have to work backwards. We must "divide a number by 5" so we start out with [tex]\frac{n}{5}[/tex]. "n" represents the number that we do not know yet. Then we must "add 4 to the result" so the equation will now look like this: [tex]\frac{n}{5} + 4[/tex]. The problem also states that the answer is 9. Now, the final equation looks like this: [tex]\frac{n}{5} + 4=9[/tex].
If you need to, guess and check is a good way to complete multiple choice questions (until you're able to get help). I recommend asking your teacher for a more in depth explanation if you still don't understand.

a. name the vertex of <4 b. Name the sides of <1 c. Write another Name for <5 d. classify each angle
Answers
Answer:
A. vertex B
B. Side BC and BD
C. Angle EBD
Step-by-step explanation:
An angle is an undefined term in plane geometry.
The vertex of [tex]\angle 4[/tex] is BThe sides of [tex]\angle 1[/tex] are BC and BDAnother name for [tex]\angle 5[/tex] is [tex]\angle DBE[/tex].[tex]\angle FBC[/tex] is a right angle[tex]\angle EBF[/tex] is an obtuse angle [tex]\angle ABC[/tex] is a straight angle.[tex]\angle EBC = 144[/tex][tex]\angle ABE =13.5[/tex]Vertex of [tex]\angle 4[/tex]
The vertex of an angle is the point where the rays that form the angle meet.
From the diagram, rays BE and BA meet at point B to form [tex]\angle 4[/tex].
Hence, the name of the vertex is B
Sides of [tex]\angle 1[/tex]
The sides of an angle are the rays or sides that form the angle
[tex]\angle 1[/tex] is formed by rays BC and BD
Hence, the sides are BC and BD
Another name for [tex]\angle 5[/tex]
An angle can be named by combining the sides and the vertex.
The sides of [tex]\angle 5[/tex] are DB and BE, while the vertex is B
This means that rays DB and BE meet at point B
Hence, another name is [tex]\angle DBE[/tex]
Classify the angles
Angles are classified based on the measure
[tex]\angle FBC[/tex] is a right angle, because [tex]\angle FBC = 90^o[/tex]
[tex]\angle EBF[/tex] is an obtuse angle because [tex]\angle EBF[/tex] is greater than [tex]90^o[/tex] but less than [tex]180^o[/tex]
[tex]\angle ABC[/tex] is a straight angle, because [tex]\angle ABC= 180^o[/tex]
Angle bisector
The line or ray that divides an angle into equal halves is an angle bisector.
Ray BE is an angle bisector, because it divides [tex]\angle DBA[/tex] into two equal halves.
Find [tex]\angle EBC[/tex]
We have:
[tex]\angle EBD = 36[/tex]
[tex]\angle DBC = 108[/tex]
[tex]\angle EBC[/tex] is calculated using:
[tex]\angle EBC = \angle EBD +\angle DBC[/tex]
[tex]\angle EBC = 108+36[/tex]
[tex]\angle EBC = 144[/tex]
Find [tex]\angle ABE[/tex]
We have:
[tex]\angle EBF = 117[/tex]
[tex]\angle DBC = 108[/tex]
[tex]\angle ABE[/tex] is calculated using:
[tex]\angle EBF = \angle ABE +\angle EBD + \angle ABF[/tex]
Where
[tex]\angle ABF = 90[/tex]
[tex]\angle ABE = \angle EBD[/tex]
So, we have:
[tex]117 = \angle ABE +\angle ABE + \angle 90[/tex]
[tex]117 = 2\angle ABE + 90[/tex]
Collect like terms
[tex]2\angle ABE =117 - 90[/tex]
[tex]2\angle ABE =27[/tex]
Divide both sides by 2
[tex]\angle ABE =13.5[/tex]

which of the following functions is graphed below?
Answers
Step-by-step explanation:
For y = x^3 - 4 when x = 0, y = -4.
For y = x^2 + 3 when x = 0, y = 3.
Looking at the graph, the y-intercept of the function is below 0. Hence the bottom part is from x^3 - 4 and the top is from x^2 + 3.
The bottom part has a dark circle, which means when x = 1 it belongs to x^3 - 4.
Hence the answer is D.
