Answer:

x = 6

FE = 28

Step-by-step explanation:

The triangles are similar so their side lengths are proportional

we can use that proportional value to find x and FE

(5x-2)/42 = (4x+2)/39 cross multiply expressions

195x - 78 = 168x + 84 get like expressions to the same side of the equation

195x - 168x = 84 + 78

27x = 162 divide both sides by 27

x = 6 now to find FE replace x with 6 in the expression

5x - 2 = 5×6 - 2

FE = 28

Answer:

No

Step-by-step explanation:

2(0)+7

=0+7

=7

therefore,(0,7) is not a solution to the equation 2x+y=6

0=×

7=y

Answer: no it isn’t

Step-by-step explanation: this is super simple so do solve this you have know your x and y values on coordinate points in this case (0,7) our x here is 0 and our y is 7 (the x will always be the first number and the y will be the last)

Here we are given a equation all we have to do is plug 0 for x and 7 for y.
2(0)+7=6

2 x 0= 0

So: 0+7=7

7 does NOT equal to 6 therefor (0,7) is NOT a solution

Answer:

40

Step-by-step explanation:

Sum of all angles of triangle = 180°

∠W + ∠X + ∠Y = 180

10x + 17 + 2x - 9 + 3x + 7 = 180

10x + 2x  +3x + 17 - 9 + 7 = 180

Combine like terms

15x + 15 = 180

       15x = 180- 15

         15x = 165

            x = 165/15

x = 11

∠Y =  3x +7  = 3*11 + 7 = 33 + 7 = 40

Answer:

X is 11 and after substitution y is 40

Answer:

c = 14.9

Step-by-step explanation:

use the pythagorean thereom:

a² + b² = c²

a² = 11 × 11 = 121

b² = 10 × 10 = 100

c² = 121 + 100 = 221

now find the square root of 221:

√221 = 14.866...

round to the nearest tenth:

the 6 next to the 8 means round up.

so the hypotenuse is 14.9

Hi there!

The area of the shaded region is equal to the area of the big rectangle minus the area of the square.

Area of the big rectangle:

Answer:

Step-by-step explanation:

Number series : 9, 14, 19, 24

First term = a1 = 9

common difference = a2 - a1 = 14 - 9=5

Find the nth term:

an = a1 + + (n - 1)d

an = 9+ (n - 1)(5)

an = 9+5n - 5

an = 4 + 5n

Find the 10th term:

an = 4 + 5n

a10 = 4 + 5(10)

a10 = 4 + 50

a10 = 54

Find the 50th term:

an = 4 + 5n

a50 = 4 + 5(50)

a50 = 254

Find the difference between the 10th and

50th term:

Difference = 254 - 54 = 200

Answer: The difference is 200

Given the data from the question, the difference between the 10th term and the 50th term is 200

This is a type of sequence which have common difference between each term. It is represent mathematically as:

Tₙ = a + (n – 1)d

Where

Tₙ = a + (n – 1)d

T₁₀ = 9 + (10 – 1)5

T₁₀ = 9 + (9)5

T₁₀ = 9 + 45

T₁₀ = 54

Tₙ = a + (n – 1)d

T₅₀ = 9 + (50 – 1)5

T₅₀ = 9 + (49)5

T₅₀ = 9 + 245

T₅₀ = 254

Difference = T₅₀ – T₁₀

Difference = 254 – 54

Difference = 200

Answer:

a^1=1

a^8=16,384

Step-by-step explanation:

The original equation of a^n=4^n-1 uses n as a placeholder variable for whatever value is needed to solve the equation. For the first question, which gives 1=n, substituting 1 into the equation gives you the answer of 1. 1-1=0. You can not have any number to the power of zero however, so due to the multiplicative identity, you end up with a positive 1.

The second one we are given 8=n. 8-1 equal 7. 4 to the power of seven (multiply 4 by itself 7 times) gets you 16, 384.

Given the sequence defined as [tex]a_{n} = 4n - 1[/tex], [tex]a_{1} =3\ and\ a _ {8} = 31[/tex].

An arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k.

[tex]a_{n} = a_{1} + (n-1)d[/tex]

Given sequence:

[tex]a_{n} = 4n - 1\\\\a_{1} = 4 * 1 - 1 = 4 - 1 =3\\\\a _ {8} = 4 * 8 - 1 = 32 - 1 = 31[/tex]

Step-by-step explanation:

The G(x) is the new function of the f(x) which is translated 4 units down is 4x²+2.

A function assigns the value of each element of one set to the other specific element of another set.

The given function can be transformed from the initial position of the new position by subtracting the 4 from the initial function.

We know that in the initial function y=4x²+6, y is the output, while x is the input for the function f(x).

As the G(x) is the new function of the f(x) which is translated 4 units down. therefore,

[tex]G(x) = f(x)-4\\\\G(x) = 4x^2+6-4\\\\G(x) =4x^2+2[/tex]

hence, the G(x) is the new function of the f(x) which is translated 4 units down is 4x²+2.

Answer:

mean = 24

Step-by-step explanation:

From inspection, there are 7 values.

The values are 12, 13, 15, 28, 28, 30, 42

To find the mean, sum the numbers: 12 + 13 + 15 + 28 + 28 + 30 + 42 = 168

Divide by the number of values:  168 ÷ 7 = 24

Therefore, mean = 24

Answer:

x =5

Step-by-step explanation:

c = 5√2

a = x

b = x

Formula

x^2 + x^2 = c^2                    Combine the x^2

Solution

2x^2 = (5√2)^2                    Expand the right side

2x^2 = 2*25                         Divide both sides by 2

x^2 = 25                               Take the square root of both sides.

x = 5
