Answer:x=13

Step-by-step explanation:

Since they are both corresponding angles you can create the equation

5x+21=86

Subtract 21 from each side

5x=65

Divide each side by 5

X=13

I believe the answer is 5/7=15/DG.

Please, do correct me if the answer seems wrong, thank you.

The proportion which can be used to describe the value of DG is

15 x 7 = 5 x DG

What are similar triangles?

Two triangles are said to be similar if their sides are proportional and their angles are equal.

Given data ,

The two triangles are ΔABC and ΔDFG are similar

Length of AB = 5 inches

Length of BC = 6 inches

Length of AC = 7 inches

Length of DF = 15 inches

Length of FG = 18 inches

And , ∠B is congruent to ∠F

The two triangles are similar , so the ratio of

AB / DF = BC / FG = AC / DG

Therefore , 5 / 15 = 7 / DG

DG = 21 inches

Hence , the proportion used to find the value of DG is 15 x 7 = 5 x DG

Answer:

y=100

Step-by-step explanation:

You can solve this by comparing the ratio.

The first set is 10:20 or 1:2 when simplified.

This can then be applied to the second set. If x=50, then 50 times 2 will give you the answer of 100.

Answer:

6 hours

Step-by-step explanation:

Given that:

Time taken by Sam = 3 hours

Sam's rate = 1/3

Time taken : Sam + Laura = 2 hours

Sam's rate + Laura's rate = 1/2

Let time taken by Laura = x

1/3 + 1/x = 1/2

1/x = 1/2 - 1/3

1/x = (3 - 2) / 6

1/x = 1 /6

x = 6

Hencw, it will take 6 hours for Laura alone to rake leaves

You have 3 eggs.

Step-by-step explanation:

You "had" 4 eggs, those  do not count.  A thief then gave you 3 eggs. And lastly, a rooster does not lay eggs. In conclusion, you have 3 eggs.

The total number of eggs he finally has as inferred from the riddle is 3 eggs.

Evaluating each sentence :

If I had 4 eggs ; This is an imagination, hence, the speaker was only imagining if he had. Hence, total here is 0

A thief gave out 3 eggs ; Hence, the total number of eggs = (0 + 3) = 3 eggs

Farm Rooster laying 5 eggs is impossible S Farm roosters do not lay eggs. Number of eggs here is 0.

Hence, the total number of eggs = (0 + 3 + 0) = 3 eggs.

From the question we are told that

   The sample space is  n =  6 (i.e six sides)  

     The number of even numbers in the sample space is  k  = 3 (i.e  2,4, 6)

Generally the probability of rolling an even number with a six-sided, equally weighted die is mathematically represented as

       [tex]P(E) = \frac{3}{6}[/tex]

=>     [tex]P(E) = \frac{1}{2}[/tex]

3y > 2x + 12

[tex]y>\frac{2}{3}x+4[/tex]

This inequality will be represented by the a dotted line and solution area for the inequality will be shaded area (In red) above the dotted line.

2x + y ≤ -5

y ≤ -2x - 5

This inequality will be represented by a solid line and solution area will be the shaded area (in blue) below the solid line.

Therefore, common area of both will be the solution area for the system of inequalities.

Step-by-step explanation:

Answer:

We have the function:

f(x) = 3*x^5 - 4*x^3 - 3*x

To find the maximum/minimums, we first need to look at the roots of the first derivative of f(x), this is:

f´(x) = 5*3*x^4 - 3*4*x^2 - 3

f´(x) = 15*x^4 - 12*x^2 - 3

We can do the change of variable:

u = x^2

Then we can rewrite:

f'(u) = 15*u^2 - 12*u - 3

This is a quadratic equation, the solutions will be obtained by the Bhaskara´s equation:

So the solutions are:

[tex]u = \frac{+12 +- \sqrt{(-12)^2 - 4*(-3)*15} }{2*15} = \frac{12 +- 18}{30}[/tex]

Then the two solutions are:

u = (12 + 18)/30 = 1

this leads to:

x^2 = 1, then we can have x = ± 1

the other solution is:

u = (12 - 18)/30 = -6/30 = -(1/5)

and x^2 = -(1/5), then:

x = ±√(1/5)*i

So those are the possible values for the minimum/maximums.

Now to see it, we need to look at the second derivative ad see iff:

f´´(x) > 0 then x is a minimum

f''(x) < 0, then x is a maximum.

We have that:

f´´(x) = 4*15*x^3 - 2*12*x

f´´(x) = 60*x^3 - 24*x

Notice that the two complex roots will lead to complex values of f(x), so these can be ignored here, then we have to try only with x = ± 1.

f´´(1) = 60*1^3 - 24*1 = 36

then x = 1 is a minimum.

f´´(-1) = 60*(-1)^3 -24*-1 = -36

then x = -1 is a maximum.

Then we can conclude that the relative maximum is at x = -1

The function f given by [tex]f(x) = 3x^5-4x^3-3x[/tex] has a relative maximum at

x = -1

The given function is:

[tex]f(x) = 3x^5-4x^3-3x[/tex]

Find the derivative of the function:

[tex]f'(x)=15x^4-12x^2-3[/tex]

Find the critical points by equation f'(x) to zero

[tex]15x^4-12x^2-3=0\\\\5x^4-4x^2-1=0[/tex]

By solving the equation above, the critical points are:

x = -1,  x =  1

Find the second derivative of f(x)

[tex]f''(x)=60x^3-24x[/tex]

[tex]f''(-1)=60(-1)^3-24(-1)\\\\f''(-1)=-36[/tex]

Since f''(-1) < 0, x = -1 is a maximum point

[tex]f''(1)=60(1)^3-24(1)\\\\f''(1)=36[/tex]

Since f''(1) > 0, x = 1 is a minimum point

Therefore, the function [tex]f(x) = 3x^5-4x^3-3x[/tex] has a relative maximum at x = -1
