Answer:
I believe the answer is B. 15/5 = n/12
Step-by-step explanation:
Once again same method as I've explained before. However, this one tricked me a little bit and still is because of the appearance of the smaller triangle. However, If I don't focus on that I believe this answer is correct. This is because in order to find the missing side we need to find the factor of which the triangle was expanded. So we must divide a given side of the bigger triangle by the same similar side of the little triangle, like 15/5. Then we must divide n by its similar side which the appearance made me think 13 which is not an option so I believe it is 12 and it was just trying to throw me off. So n/12. Therefore that is why I believe B is correct.

How many solutions does the equation 4(x-1)=1/2(x-8) have?

Step-by-step explanation:
Answer:
It just has one solution :)
Step-by-step explanation:
4(x+1)=1/2(x-8)
4x-4 = 1/2(x-8)
4x-4=1/2x-4
4x=1/2x
8x=x
(8x-x=0)

Okay, so of course you need to add like terms. But where should you start? Well, [tex]6x^{2}[/tex] and [tex]-5x^{2}[/tex] are both like terms, so lets add them first.
[tex]6x^{2} -5x^{2} = x^{2}[/tex]
Also, [tex]-4xy[/tex], [tex]2xy[/tex], and [tex]10xy[/tex] are like terms, so we can add them together too.

There isn't anymore like terms, so now we need to put it in simplest form.

The slope of AB is different from the slope of BC
==================================================
Reason:
Points A,B,C are all on the same line. We consider them collinear points. This means that the slopes of AB, AC and BC are the same value.
If the slopes were different at all, then the points wouldn't be collinear. In this case, the slope is 2/3 because we move up 2 each time we move to the right 3 units.

In a function, y varies directly with x and the constant variation is 2, then the function is y=2x. Therefore, option D is the correct answer.
What is direct variation?Mathematical relationship between two variables which can be expressed by an equation in which one variable is equal to a constant times the other.
Given that, in a function, y varies directly with x and the constant variation is 2.
y∝x
y=kx, where k is constant variation.
Here, k=2
Then, y=2x
When x=1, 2, 3, 4 and 5.

Answer:
m∠4 = 140°
Step-by-step explanation:
m∠1 = m∠4 (parallel lines with same angle)
m∠2 = m∠3 (parallel lines with same angle)
if m∠2 = m∠3 are equal:
3x + 10 = 5x - 10
3x - 5x = -10 - 10
-2x = -20
x = 10°
m∠2 = m∠3 = 3x + 10 = 3(10) + 10 = 40°
m∠1 + m∠4 + 40° + 40° = 360°
2 m∠4 = 360° - 80°
2 m∠4 = 280°
m∠4 = 140°
Answer:
m∠4 = 140°
Step-by-step explanation:
Vertical Angle Theorem: vertical angles are always congruent.
Therefore, m∠1 = m∠4 and m∠2 = m∠3
As m∠2 = m∠3, then
⇒ 3x + 10 = 5x - 10
⇒ 20 = 2x
⇒ x = 10
So m∠2 = 3x + 10 = 3(10) + 10 = 40°
m∠2 and m∠4 form a linear pair
Therefore m∠2 + m∠4 = 180°
⇒ 40 + m∠4 = 180
⇒ m∠4 = 140°
Linear pair: a pair of adjacent angles formed when two lines intersect. The two angles of a linear pair always sum to 180°

Answers
Answer:
m = 4√6
Step-by-step explanation:
Using the "geometric mean" relations applicable to this triangle, the value of m is the geometric mean of the hypotenuse segments it touches:
m = √((8)(8+4)) = √96
m = 4√6
__
Additional comment
Similarly, n = √(4×8) = 4√2.
These relations come from the similarity of the triangles. For m, the proportion is ...
long side/hypotenuse = 8/m = m/12
96 = m² ⇒ m = 4√6

The area of each rectangle is the product of its length and width. The shaded area is the difference between the areas of the outside rectangle and the inside rectangle.
shaded area = (2x -1)(x +6) -(2x +5)(x +2)
= (2x^2 +11x -6) -(2x^2 +9x +10)
