If we know that the angle on the left is 80° we know that the angle on the right is also 80°

We can subtract these from 360° and we are left with 200°

Since all four of the remaining angles are congruent we can divide our remaining 200° by 4

When you do that you get 50, meaning each remaining angle is 50°

Making x=50°

Hope this helped!

Answer:

x = 50

Step-by-step explanation:

There are no guarantees that the question can be answered unless the lines meeting at the intersection point are staight lines. You have to assume that to be true.

The angles making up the line starting at the lower right and going up to the upper left are

80 +x + x = 180            80 and one of the two xs are vertically opposite.

80 + 2x = 180               Subtract 80 from both sides.

80-80+2x=180-80        Subtract

2x = 100                        Divide by 2

2x/2 =100/2

x = 50

Answer:

29

Step-by-step explanation:

The n th term of an arithmetic sequence is

• [tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

d = 1 - 7 = - 5 - 1 = - 6 and a₁ = 7, [tex]a_{n}[/tex] = - 161, hence

7 - 6(n - 1) = - 161 ← solve for n

7 - 6n + 6 = - 161

13 - 6n = - 161 ( subtract 13 from both sides )

- 6n = - 174 ( divide both sides by - 6 )

n = 29

There are 29 terms in the sequence

x = 16.

Hope this helps!

Answer:

x = 16

Step-by-step explanation:

Since the triangles are similar then the ratio of corresponding sides are equal, that is

[tex]\frac{x}{4}[/tex] = [tex]\frac{20}{5}[/tex] ( cross- multiply )

5x = 80 ( divide both sides by 5 )

x = 16

Answer:

Yes, there exists one output for every input

Step-by-step explanation:

* Lets revise how to test the function is one-one function

- Draw a horizontal line (parallel to x-axis) and moved it up and down

- If the horizontal line cut the graph in more than one point, then

 the function is not one-one function

- If the horizontal line cut the graph in only one point, then the

 function is one-one function

- That means one output for every input

* Now lets look to the graph

- If we draw a horizontal line and moved it up and down, the line

 will cut the graph in just one point

- That means every x has different value of y

∴ There is no same y-coordinate for two x-coordinates

* Yes, there exists one output for every input

x would be 7 units because 4 × 7 = 28 And 28 + 10 = 38

Answer:

Step-by-step explanation:

1. 0.4y = x is a direct proportion.  It'd be more appropriate to write this as

   y =  x / 0.4, or y = 2.5x, in which case 2.5 is the constant of proportionality.

2. x = 1 - 2y is not a direct proportion because of the offset (1).  A line representing a direct proportion must go through the origin (0, 0); this particular line does not do that.

The first equation, 0.4y = x, represents a direct proportion with the constant of proportionality being 2.5. The second equation, x = 1 - 2y, does not represent a direct proportion since it does not have the form y = kx.

When we talk about two quantities being directly proportional, we mean that as one quantity increases, the other increases by a constant rate, and vice versa. This relationship can be represented by the equation y = kx, where k is the constant of proportionality.

For the first equation, 0.4y = x, this is rearranged as y = (1/0.4)x or y = 2.5x. This is indeed a directly proportional relationship, with the constant of proportionality being 2.5.

The second equation x = 1 - 2y does not describe a directly proportional relationship because it is not of the form y = kx. Instead, it shows that x decreases as y increases, which is suggestive of an inverse relationship, rather than a direct one.

Answer:

3 weeks

Step-by-step explanation:

1 quart = 2 pints

6 quarts = 12 pints,

so 4 pints each week would take 3 weeks (4pints x 3weeks =12pints)

y = 3x - 5

So substitute 3x-5 for y:

6x + 3(3x-5) = 15

Simplify:

6x + 9x - 15 = 15

15x - 15 = 15

x - 15 = 1

x = 16

THEN find y by plugging the value of x back into the first equation:

y = 3(16) - 5

y = 48 - 5

y = 43

You need to use substitution, to do so, you isolate one of the variables x or y in one equation, and then you substitute that equation into the other.

Since you only need to find x, isolate the y in one of the equations

x - 2y = 4

y = [tex]\frac{x}{2} -2[/tex]

Plug this in and simplify

9x + 2y = 16

9x + 2([tex]\frac{x}{2} -2[/tex]) = 16  Distribute the 2

9x + x - 4 = 16  

10x = 20

x = 2    Your answer is C

Answer:

[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Substitute x = 2 into both h(x) and f(x)

h(2) = [tex]\frac{1}{2-1}[/tex] = 1 ⇒ (h(2))² = 1

f(2) = 2 + 2 = 4

Hence

[tex]\frac{h(x)^2}{f(x)}[/tex] when x = 2

= [tex]\frac{1}{4}[/tex]

1/4 is the following function at x=2​

A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and co domain, respectively. Initially, functions represented the idealized relationship between two changing quantities.

Given

Substituting x = 2 into both h(x) and f(x)

h(2) = 1(2-1) = 1 ⇒ (h(2))² = 1

f(2) = 2 + 2 = 4

Hence

h(x)²/f(x)  when x = 2

=1/4

Answer:

The expression of this sequence is -9n

Step-by-step explanation:

* Lets revise the type of the sequence

- Arithmetic sequence:

- There is a constant difference between each two consecutive

 numbers

* Ex:

# 2  ,  5  ,  8  ,  11  ,  ……………………….

# 5  ,  10  ,  15  ,  20  ,  …………………………

# 12  ,  10  ,  8  ,  6  ,  ……………………………

* General term (nth term) of an Arithmetic Progression:

- U1 = a  ,  U2  = a + d  ,  U3  = a + 2d  ,  U4 = a + 3d  ,  U5 = a + 4d

- Un = a + (n – 1)d, where a is the first term , d is the difference

 between each two consecutive terms

* Now lets look to the problem

- The sequence is : -9 , -18 , -27 , -36

∵ -18 - (-9) = -18 + 9 = -9

∵ -27 - (-18) = -27 + 18 = -9

∵ -36 - (-27) = -36 + 27 = -9

∴ The sequence is arithmetic with common difference -9

∵ a = -9 , d = -9 and n is the position of the term in the sequence

∴ The rule of the sequence is Un = -9 + (n -1)(-9)

* We can simplify it

∴ Un = -9 + n(-9) - (1)(-9) = -9 + (-9n) - (-9) = -9 - 9n + 9 = -9n

* The expression of this sequence is -9n

The expression describing the sequence -9, -18, -27, -36, ... is –n, where n represents the position of the term in the sequence.

The sequence given is -9, -18, -27, -36, ..., and we need to write an expression using n to represent the position of a term in the sequence. This is clearly an arithmetic sequence because each term is obtained by adding a constant value to the previous term. The common difference here is -9 (since -18 - (-9) = -9).

For an arithmetic sequence, the n-th term is given by the formula an = a1 + (n - 1) × d, where a1 is the first term, and d is the common difference. In this case, a1 = -9 and d = -9. Therefore, we can substitute these values into the formula to get:

an = -9 + (n - 1) × (-9)

which simplifies to:

an = -9n
