Exponential Function.

y =  {a}^{x}  \:  \: (a > 0) \:  \: (a≠1)

Also the shown graph is a decreasing graph.

y =  {a}^{x}  \:  \: (0 < a < 1)

The equation above is the equation of the graph that is shown in the picture.

Please help me find x. I really don't get it.
inysia [295]

Answer:

  x = 11

Step-by-step explanation:

The relationship between the sine and cosine functions can be written as ...

  sin(x) = cos(90 -x)

  sin(A) = cos(90 -A) = cos(B) . . . . substituting the given values

Equating arguments of the cosine function, we have ...

 90 -(3x+4) = 8x -35

  86 -3x = 8x -35

  86 +35 = 8x +3x . . . . . add 3x+35 to both sides

  121 = 11x . . . . . . . . . . . . collect terms

  121/11 = x = 11 . . . . . . . . divide by 11

_____

<em>Comment on the solution</em>

There are other applicable relationships between sine and cosine as well. The result is that there are many solutions to this equation. One set is ...

  11 +(32 8/11)k . . . for any integer k

Another set is ...

  61.8 +72k . . . . . for any integer k

Bruno solved the following equation: 4x + one half(10x − 4) = 6 Step Work Justification 1 4x + 5x − 2 = 6 2 9x − 2 = 6 3 9x = 8
beks73 [17]

Answer:

Statement                                   Reason

1. 4x+5x-2=6                 1. Distributive Property

2. 9x-2=6                        2. Combine like terms

3. 9x=8                              3. Addition Property of Equality

4. x=\dfrac{8}{9}                               4. Division Property of Equality

Step-by-step explanation:

The given equation is

4x+\dfrac{1}{2}(10x-4)=6

Using distributive property, we get

4x+\dfrac{1}{2}(10x)+\dfrac{1}{2}(-4)=6

4x+5x-2=6

9x-2=6         (Combine like terms)

Using Addition Property of Equality, add 2 on both sides.

9x=6+2

9x=8

Using Division Property of Equality, divide both sides by 9.

x=\dfrac{8}{9}

Find the value of x and y
allsm [11]

We have the equations:

x + 3 = 15 and 3y - 1 = 2x - 4

x + 3 = 15    |-3

x = 12

Put the value of x to the second equation:

3y - 1 = 2(12) - 4

3y - 1 = 24 - 4

3y - 1 = 20     |+1

3y = 21    |:3

y = 7


<h3>Answer: x = 12 and y = 7.</h3>

7 Point Question Tyler was trying to prove that all rhombuses are similar. He thought, “If I draw 2 rhombuses, I can find dilati
Viefleur [7K]

A rhombus can have the same shape and dimension as a square or a

parallelogram, therefore, all rhombuses are not similar.

  • A step in the proof that have flaws is <u>step 3</u>.

Reasons:

By reading through the given steps, we have, the first step that is incorrect

is step 3.

Step 3: The requirement for the similarity of two figures based on the

proportionality of the corresponding sides of the figures is related with

triangles as given by the triangle proportionality theorem.

This is so because, the lengths of the sides of a triangle depends on the

opposite interior angle, while the side of a rhombus can have a

combination of large length and and acute angle.

Two rhombuses that have proportional sides may be dissimilar,

because they can have different interior angles.

Therefore;

<u>The step in Tyler's proof that have a flaw is Step 3</u>
