find the real numbers x and y that make the equation true (5-2i)-7=x-(3-yi)
Answer:
x=1 and y=-2
Step-by-step explanation:
5-2i-7=-2-2i
x-(3-yi)=x-3+yi
we write this equation -2 - 2i = (x-3) +yi
so -2=x-3 and -2i=yi
+3 +3 :i :i
1=x -2= y
so x=1 and y= -2
what is the least common denominator of 8 and 12
Answer:
The least common denominator of 8and 12 is 24
The least common denominator of the numbers 8 and 12 is 4.
The given numbers are 8 and 12.
When two or more fractions have the same denominators, they are termed as the common denominators. The least common denominator (LCD) refers to the smallest number that is a common denominator for a given set of fractions.
Here, the factors of the given numbers are
8 = 2×2×2
12 = 2×2×3
So, the common factor is 2×2=4
Therefore, the least common denominator of 8 and 12 is 4.

a. name the vertex of <4 b. Name the sides of <1 c. Write another Name for <5 d. classify each angle
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?
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.
