Answer:
x = - 3, y = 6
Step-by-step explanation:
For the 2 sides to be equal then the coefficients of the imaginary terms and the real terms must be equal.
Given
- 3 + yi = x + 6i , then
x = - 3 and y = 6

2x - 2 = 45 + x
2x - x = 45 + 2
x = 47°
Answer:
x = 47
Step-by-step explanation:
Finding the third angle (y) of the triangle:
- Since angles on a straight line add up to 180:
2x -2 + y = 180
y = -2x + 2 + 180
= -2x + 182
Hence, the third angle of the triangle is -2x + 182.
Since all 3 angles of a triangle add up to 180°:
-2x + 182 + x + 45 = 180
-2x + x + 227 = 180
-2x + x = 180 - 227
-x = -47
x = 47
Hence, x = 47

Triangle ACB with coordinates A(0,0), C(2,0), and B(2,4) is similar to triangle BED. If vertex D has coordinates (6,12), what are the coordinates of vertex E?
Answer:
A right triangle is a triangle that has 90 degrees angle in one of its parts. You are given two points that have coordinate:
x1,y1= (-2, 4)
x2,y2= (-1,1)
To make the angle 90 degrees, there is two possible third point coordinate:
1. x1, y2 = (-2,1)
2. x2, y1= (-1,4)
The right triangle would be option C: (-2,1)
Option A and B is not a right triangle
Step-by-step explanation:
Answer:
the coordinates of vertex E is (6,0)
C(2,0),compare this to(2,4)
same x.but y=0
(6,0)comparing to (6,12)

Step-by-step explanation:
1.5 divided by 1/3 is 4.5, and 4.5 is equal to 4 1/2
Answer:
Sage did it right.
your work:
1 1/2 ÷ 1/3
3/2 ÷ 1/3
3/2 × 3/1
9/2
4 1/2
Step-by-step explanation:
first convert 1 1/2 into an improper fraction:
multiply the 2 and 1, you get 2, than add that to the current numerator to get a new one. You get 3/2 as your improper fraction
you now have: 3/2 ÷ 1/3
then turn the division sign into a multiplication sign by flipping the divisor:
you get 3/2 × 3/1
solve this:
multiply the numerators together, you get 9 as a new numerator
multiply your denominators, you get 2 as your new denominator
so now you have 9/2
next turn this into a mixed fraction, you get 4 1/2
so Sage did it right.

by the definition of supplementary angles, the base angles of the top isosceles triangle have the measure of
Answer:
128
Step-by-step explanation:
Top Triangle
Let the base angles of the top triangle = y
y + 102 = 180
y = 78
The vertex
Is found by adding the two base angles together and subtract that from 180
y + y + vertex = 180
78 + 78 + vertex = 180
156 + vertex = 180
vertex = 180 - 156
vertex = 24 degrees
Bottom Triangle
Because the base angles are connected by a vertically opposite angle on the bottom triangle, both base angles are 26
Therefore 26 + 26 + x = 180
52 + x = 180
x = 180 - 52
x = 128

Tim thinks that the following expression will only yield values that are positive. x^2
Is Tim correct? Explain why or why not and provide three examples that prove whether Tim’s statement is correct.
Answer:
We conclude that Tim is correct when he says that the expression x² only yields values that are positive.
Step-by-step explanation:
Given the expression
x²
Plug in and checking x = 1 and x = -1 in the expressionPutting x = 1 in the expression
x²= (1)² = 1
Putting x = -1 in the expression
x²= (-1)² = 1
Thus, the expression yields the same output '1' when we enter x = 1, and x=-1.
Plug in and checking x = 2 and x = -2 in the expression
Putting x = 2 in the expression
x²= (2)² = 4
Putting x = -1 in the expression
x²= (-2)² = 4
Thus, the expression yields the same output '4' when we enter x = 2, and x=-2.
Plug in and checking x = 3 and x = -3 in the expressionPutting x = 3 in the expression
x²= (3)² = 9
Putting x = -1 in the expression
x²= (-3)² = 9
Thus, the expression yields the same output '9' when we enter x = 3, and x=-3.
The reason why the expression x² only yields positive values because the expression is in the square form, and the square of any number will always yield a positive value, no matter whether the input number is negative or positive.
Therefore, we conclude that Tim is correct when he says that the expression x² only yields values that are positive.
find the percent of the number
24% of 480
Answer:
115.2
Step-by-step explanation:
Answer: 115.2
Step-by-step explanation:
What is 24% of 480?
Y is 24% of 480
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 24% * 480
Converting percent to decimal:
p = 24%/100 = 0.24
Y = 0.24 * 480
Y = 115.2
Mrs. Garcia's math test is worth 50 points. If you answer all the questions and the extra credit correctly, you can score 55 points. How do you represent this situation as a fraction, a decimal, and a percent?

According to the National Oceanic and Atmospheric Administration, the blue whale is the largest animal on Earth. Blue whales weigh approximately 3×105 pounds. Narwhals, which are also a type of whale, weigh approximately 2×103 pounds. How many times heavier is the blue whale's weight than the narwhal's weight?
Answer: The blue whale's weight is 150 times heavier than the narwhal's weight.
Step-by-step explanation:
Given: Weight of Blue whale = [tex]3\times10^5\text{ pounds}[/tex]
Weight of Narwhal = [tex]2\times10^3\text{ pounds}[/tex]
Number of times blue whale's weight is heavier than the narwhal's weight = [tex]=\dfrac{\text{Weight of Blue whale}}{\text{Weight of Narwhal }}[/tex]
[tex]=\dfrac{3\times10^5}{2\times10^3}\\\\=1.5\times10^{5-3}\ \ \ [\dfrac{a^m}{a^n}=a^{m-n}]\\\\=1.5\times10^2\\\\=1.5\times100=150[/tex]
Hence, the blue whale's weight is 150 times heavier than the narwhal's weight.

Can someone please help me on this question
Answer: It's C.
Step-by-step explanation:
Solve for x
Y= x-v/b
Answer:
x=y+v/b
Step-by-step explanation:
So first you have y=x-v/b. You want to isolate x, so subtract x from both sides. You'll get -x+y=-v/b. Next, you're going to want to subtract y to further isolate x now that it's on the left side. Now you'll have -x=-y-v/b. But you don't want x to be negative, so you can divide both sides by -1 to make x positive. Now you'll have x=y+v/b.
2(3v-5)=2(v-11)-4 can someone help me out ?
Answer:
v = -4
Step-by-step explanation:
2(3v - 5) = 2(v - 11) - 4
6v - 10 = 2v - 22 - 4
+10 +10
6v = 2v -12 - 4
-2v -2v
4v = -16
divide both sides by 4
v = -4
Hope this helps!!
The value of v = - 4.
We have the following equation -
2(3v - 5) = 2(v - 11) - 4
We have to find out the value of the variable v.
What is the solution of a equation in one variable?The solution of an equation is the value of variable for which the left hand side is equal to right hand side.
We have the following equation -
2(3v - 5) = 2(v - 11) - 4
2 x 3v - 2 x 5 = 2v - 2 x 11 - 4
6v - 10 = 2v - 22 - 4
6v - 10 = 2v - 26
6v - 2v = - 26 + 10
4v = -16
v = - 4
Hence, the value of v = - 4.

Answer:
A. Juan wins the race
B. At about 7 minutes J(t )= A(t)
C. 2 minutes
Step-by-step explanation:
A. Juan wins the race. This is because she covers the distance in a shorter time interval than Antonio
B. At about 7 minutes J(t )= A(t). to get this, just look at the point that the two curves intersect on the graph, and trace it down to the time axis to read off the time.
C. J(t) is greater than A(t) with about 2 minutes. To get this, we just subtract the time Juan arrived at the finish line from the time Antonio arrived, this is = 15 -13 = 2 minutes

If you were offered $18 dollars per hour, $3,000 dollars a month or $37,000 dollars a year, which would you take if salary was the only consideration?
Answer:
I will consider $18/hour pay
Step-by-step explanation:
Before we an know which of the money to consider, we need to converted the equivalent amount in years
If $18 dollars is offered per hour, to know the equivalent amount per year.
1year = 8760hour
$18 = 1hr
x = 8760hr
x =18×8760
x = $157680
For the monthly pay
$3000 = 1month
y =12months
Since 12months are in year
Cross multiply
y = 3000×12
y = $36000
Since the hourly pay equivalent in years is greater than the monthly and yearly pay, hence I would consider $18 per hour pay
