The statement is that when ΔABC is dilated from the origin at a scale factor of 3 to create ΔA′B′C′, their corresponding angles are congruent, and their corresponding sides are proportional; therefore, the triangles are similar. The correct answer is option B
In order to prove the given statement, we will need to know that dilation is a transformation in which a figure is stretched in a particular direction by a certain factor (scale factor) while keeping its shape constant. We use this transformation to create similar figures.
When a figure is dilated, all of its corresponding sides are stretched, and the angles remain the same.The corresponding angles are the angles that have the same location in the two similar figures. The corresponding sides are the sides that have the same position in the two similar figures.
Since the triangles are similar, we can say that the corresponding sides of the triangles are proportional. On the other hand, the corresponding angles are congruent.
The correct option is B, which states that the triangles' corresponding angles are congruent, their corresponding sides are proportional, and therefore the triangles are similar.

The solutions of the given trigonometric equation are 60°, 180°, 300°.
What is a trigonometric equation?A trigonometric equation is an equation that consists of one or multiple trigonometric ratios of unknown angles.
The given trigonometric equation is:
cos (x/2) - sin (x) = 0
⇒ cos (x/2) - 2sin (x/2) cos (x/2) = 0
⇒ cos (x/2) [1 - 2sin (x/2)] = 0
Therefore, cos (x/2) = 0 = cos (90°) (x/2 can't be 270°)
⇒ x = 180°
Again, [1 - 2sin (x/2)] = 0
⇒ 2sin (x/2) = 1
⇒ sin (x/2) = 1/2
⇒ (x/2) = 30°, 150°
⇒ x = 60°, 300°

House Value
A $150,000
B $175,000
C $200,000
D $167,000
E $2,500,000
Based on the data, should Jasper use the mean or the median to make an inference about the house values in his neighborhood? (10 points)
Group of answer choices
He should use the mean because it is in the center of the data.
He should use the median because it is in the center of the data.
He should use the median because there is an outlier that affects the mean.
He should use the mean because there are no outliers that affect the mean.

Answer:
9x-12
Step-by-step explanation:
3*x = 3x
3*-4= -12
3x - 12 = 12x
12x-3x = 9x
9x-12
Answer: x = -4/3
Step-by-step explanation:
3(x−4)=12x
Step 1: Simplify both sides of the equation.
3(x−4)=12x
(3)(x)+(3)(−4)=12x (Distribute)
3x+−12=12x
3x−12=12x
Step 2: Subtract 12x from both sides.
3x−12−12x=12x−12x
−9x−12=0
Step 3: Add 12 to both sides.
−9x−12+12=0+12
−9x=12
Step 4: Divide both sides by -9.
-9x/-9 = 12/-9
x = -4/3

find the x- and y-intercepts of the line with equation 8x - 4y = -64
Answer:
x-intercept:8
y-intercept:16
Step-by-step explanation:
This is the equation of a straight line. When the line crosses the x-axis that is the x- intercept, the corresponding y-coordinate will be zero. Substituting y = 0 into the equation and solving for x gives the x-intercept.
8x-(4×0)=-64
-8x=-64
x=8 <= the x-intercept.
Similarly, when the line crosses the y-axis the corresponding x- coordinate will be zero. Let x = 0 and solve for y.
(8×0)-4y=-64
-4y=-64
y=16 <= the y-intercept .
Answer:
x = 1/2
y = -8
Step-by-step explanation:
Let's solve for x.
8x−4y=−64
Step 1: Add 4y to both sides.
8x−4y+4y=−64+4y
8x=4y−64
Step 2: Divide both sides by 8.
8x/8 = 4y−64 / 8
x= 1/2 y−8

The argument increases by
Pi over 3.
The modulus increases by a factor of 10 and the argument increases by 5π/3.
What is the modulus of the complex number?The modulus of the complex number is the magnitude of the complex number. If z is the complex number such that z= p+qi
Then the modulus of the z will be =|z|= √p²+q²
We have,
z = 5 – 5i √3
So,
Now rewrite this given equation in the form of z = r(CosΘ + iSinΘ),
For this first calculate the modulus,
|Z| = √((5√3)² + 5²)
|Z| = √(25×3 + 25)
|Z| = √(100) = 10
And,
Argument, Θ = tan⁻¹ (b/a)
Θ = tan⁻¹ (5√3/5)
Θ = tan⁻¹ (√3)
Θ = 71
Therefore, the modulus increases by a factor of 10, and the argument increase by 5π/3.

Graph joining the points (2,3), (2,5) and (2,7) is a line parallel to y – axis. Find the equation of the line.
Plz help me!
Answer:
x = 2
Step-by-step explanation:
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (2, 3), (2, 5), (2, 7) all with an x- coordinate 2, thus
x = 2 ← equation of vertical line
Answer:
x = 2
Step-by-step explanation:
Firstly, when a line is parallel to the y axis, the equation of the line is x = the x position common to the points, in this case, x = 2.
but if you want to calculate,
from the points,
x1 = 2, y1 = 3
x2 = 2, y2 = 5
x3 = 2, y3 = 7
using the formula,
y-y1/x-x1 = y2-y1/x2-x1
y-3/x-2 = 5-3/2-2
y-3/x-2 = 2/0
crossing we have,
2(x-2) = 0(y-3)
2x - 4 = 0
2x = 4
x = 2
