Answer:
x = 6
Step-by-step explanation:
Since ray DF bisects angle EDG, angles EDF and GDF are congruent. By reflexive property of congruence, ray DF is congruent to ray DF. Since all right angles are congruent, angles FED and FGD are congruent. By AAS, triangles FED and FGD are congruent. Since corresponding parts of congruent triangles are congruent, segments EF and GF are congruent, so 8x + 42 = 15x
7x = 42
x = 6

Answers
The lifetime cost of Ellen's dishwater is $1,030.44
What is Number system?
A system of writing to express the number is called number system.
Given that;
Cost of dishwasher before sales tax 9.22% is = $315
And, Sales tax = 9.22%
Hence, Total cost = 315 *( 1 + 0.0922) = 315 * 1.0922 = 344.043
And, Average of 10 times per week for the next 6 years before replacing it.
Since, There are 52 weeks in a year.
So, Average uses is calculated as,
10 * 52 * 6 = 3120
Since, cost for water = $0.09
Cost for electricity = $0.13
Total cost per uses = $0.22
Hence, Cost of uses = 0.22 * 3120 = $686.40
Now, Purchase cost = $344.043
And, Cost of uses = $686.40
Hence, Lifetime cost = $344.043 + $686.40 = $1,030.443
So, The lifetime cost of Ellen's dishwater is $1,030.44.

A company had $50,000 to invest in three funds. after one year it had $54,500. the growth
fund returned 12%, the income fund returned 8%, and the money market fund returned 5%.
the company invested twice as much in the income fund as in the money market fund. how
much did it invest in each fund?
Answers
The amount invested in the growth fund, income fund and money market fund is 20000, 20000 and 10000 respectively
Let the amount invested in the growth fund, income fund and money market fund be x, y and z respectively
As per the question, the company invested twice as much in the income market as in the money market
Therefore,
y = 2z
Equations will be:
x + 2z + z = 50000
12/100x + (8/100)*2z + 5/100z = 4500
Solving the equations
x + 3z = 50000
12x + 21z = 450000
Multiplying the first equation by 7 for equating
7x + 21z = 350000
12x + 21z = 450000
Equating these two we get
5x = 100000
x = 20000
Putting x = 20000 in 7x + 21z = 350000
z = 10000
2z = 20000
So, the amount invested in the growth fund, income fund and money market fund is 20000, 20000 and 10000 respectively

Ashley is the oldest of four siblings whose ages are consecutive even integers. If the sum of their ages is 100, find Ashley's age.
Answers
Answer:
28 yearsStep-by-step explanation:
Given conditions:Ashley is the oldest sibling There are four siblings Sum of their ages are consecutive even integers Sum of their ages is 100To Find :Ashley's age.Solution :Let,
One of the siblings age be = x
So, the other siblings ages are = x+2, x+4 and x+6
Since,
Ashley is the oldest sibling so his age is x + 6
∴ By the problem,
=> x + (x+2) + (x+4) + (x+6) = 100
(Now adding up the like terms we get)=> 4x + 12 = 100
(Transposing the like terms to same sides)=> 4x = 100 - 12
(Subtracting the like terms)=> 4x = 88
(Dividing both sides by 4)=> x = 22
Now,
We got the age of the youngest one that is 22 years
As,
Ashley is the oldest sibling so his age is
= 22 + 6 = 28 years
Hence,
The age of Ashley is 28 years (Ans)
Answer:
28 years old
Step-by-step explanation:
100/4 = 25
The ages are consecutive even numbers,
so add 1 to and subtract 1 from 25.

Find the inverse of each function. Determine whether each inverse is a function. f(x)=15-3 x
Answers
The inverse of the function f (x) = 15 - 3 x is f ⁻¹ (x) = 5 - x/3 which is also a function.
We are given the function:
f (x) = 15 - 3 x
Now, we need to find the inverse of the function.
For this, first we write the function as:
y = 15 - 3 x
Now, we will find the function in terms of x
3 x + y = 15
3 x = 15 - y
x = 5 - y/3
So, the inverse will become:
f ⁻¹ (x) = 5 - x/3
g (x) = 5 - x/3
Now, for one one function:
g (x₁) = g (x₂)
5 - x₁/3 = 5 - x₂/3
- x₁ / 3 = - x₂ / 3
x₁ = x₂
So, it is one - one.
So, the inverse is also a function as every element of x only has one image in y.
Therefore, the inverse of the function f (x) = 15 - 3 x is f ⁻¹ (x) = 5 - x/3 which is also a function.

Answers
No The extraneous solution of this equation
The given equation is
[tex]\sqrt{3x + 13}[/tex] - 5 = x
[tex]\sqrt{3x + 13 }[/tex] = x + 5
We have to find the value of x, so we need to square both sides of the equation
[tex](\sqrt{3x + 13} )^{2}[/tex] = [tex](x + 5)^{2}[/tex]
3x + 13 = [tex]x^{2}[/tex] + 10x + 25
[tex]x^{2}[/tex] + 7x + 12 = 0
[tex]x^{2}[/tex] + 4x + 3x + 12= 0
x( x + 4) + 3( x + 4) =0
(x + 4) ( x + 3 ) = 0
x = - 3, -4
To find the value of the extraneous solution we need to put both the value of x in the equation
x = -3
[tex]\sqrt{(3 * -3) + 13}[/tex] - 5 = -3
[tex]\sqrt{-9 + 13}[/tex] - 5 = -3
[tex]\sqrt{4}[/tex] - 5 = -3
2 - 5 = -3
-3 = -3
Now
x = -4
[tex]\sqrt{(3 * -4 ) + 13}[/tex] - 5= -4
[tex]\sqrt{-12 +13}[/tex] - 5 = -4
[tex]\sqrt{1}[/tex] - 5 = -4
-4 = -4

For item a, the linear functions are given as follows:
1. y = 1.5x.
2. y = 0.5x - 1.
3. y = -0.5x + 1.
4. y = -1.5x - 1.
For item B, we have that:
1. The functions are:
a. y = 2x + 3.
b. y = 0.5x - 1.
2. The unit rates(slopes) are:
a. 2
b. 0.5.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Item AIn graph 1, the function goes through (0,0), hence b = 0, and through point (2,3), hence the slope is:
m = (3 - 0)/(2 - 0) = 3/2 = 1.5.
Hence the function is:
y = 1.5x.
In graph 2, the function goes through (0,-1), hence b = -1, and through point (2,0), hence the slope is:
m = (0 - (-1))/(2 - 0) = 1/2 = 0.5.
Hence the function is:
y = 0.5x - 1.
In graph 3, the function goes through (0,1), hence b = 1, and through point (2,0), hence the slope is:
m = (0 - 1)/(2 - 0) = -1/2 = -0.5.
Hence the function is:
y = -0.5x + 1.
In graph 4, the function goes through (0,-1), hence b = -1, and through point (2,-4), hence the slope is:
m = (-1 - (-4))/(0 - 2) = -3/2 = -1.5.
Hence the function is:
y = -1.5x - 1.
Item BIn table a, the function goes through (0,3), hence b = 3, and through point (1,5), hence the slope is:
m = (5 - 3)/(1 - 0) = 2.
Hence:
y = 2x + 3.
The unit rate, which is the slope, is of 2.
For table b, the function goes through (2,0) and (6,2), hence the slope is:
m = (2 - 0)/(6 - 2) = 1/2 = 0.5.
Hence:
y = 0.5x + b.
When x = 2, y = 0, hence we can find b as follows.
0 = 0.5(2) + b
b = -1.
Thus:
y = 0.5x - 1.
The unit rate is of 0.5.

The symbol used to denote greater inequality is “>”. It is the commonly accepted mathematical notation of two strokes of equal length that meet at an acute right angle.
A typical use of the greater than sign is to compare two values, where the first is greater than the second, or one is greater than the other.
The greater than sign is an approximation of a closing square bracket.

The given function → f(x) = x⁵ - 3x³ is odd in nature.
What are even and odd functions?A function f(x) is even if f(−x) = f(x) and is odd if f(−x) = − f(x).
Given is the function -
f(x) = x⁵ - 3x³
In order to find f(-x), replace 'x' by '-x' in f(x) -
f(x) = x⁵ - 3x³
f(-x) = (-x)⁵ - 3(-x)³
f(-x) = - x⁵ + 3x³
f(-x) = 3x³ - x⁵
Now -
f(-x) ≠ f(x)
So, it is not a even function.
In order to find '-f(x)', multiply f(x) by '-1' -
f(x) = x⁵ - 3x³
- f(x) = - (x⁵ - 3x³) = - x⁵ + 3x³ = 3x³ - x⁵
Now -
f(-x) = -f(x)
