Solve the equation.
-X + 8 + 3x = x - 6
x = -18
x = -14
x = 2
x= 4
[tex]\sf \longmapsto-x + 8 + 3x = x - 6[/tex]
Combine like terms[tex]\sf \longmapsto(−x+3x)+(8)=x−6[/tex]
[tex]\sf \longmapsto2x+8=x−6[/tex]
Subtract x from both sides[tex]\sf \longmapsto2x+8−x=x−6−x[/tex]
[tex]\sf \longmapsto \: x+8=−6[/tex]
Subtract 8 from both sides[tex]\sf \longmapsto \: x+8−8=−6−8[/tex]
[tex]\sf \longmapsto \: x=−14[/tex]
[tex] \sf \: x = - 14[/tex]
Answer:
x = -14
Step-by-step explanation:
Equation:
-x + 8 + 3x = x - 6
Solution:
-x + 8 + 3x = x - 62x+8 = x-62x - x +8 = -6x + 8 = -6x = -6-8x = -14Second choice is accurate.
Find a positive number for which the sum of it and its reciprocal is the smallest (least) possible. Let x be the number and let S be the sum of the number and its reciprocal. Write the objective function in terms of x. S(x) nothing The interval of interest of the objective function is nothing. (Simplify your answer. Type your answer in interval notation.) The number is 0.
Answer:
[tex]S(x) = x + \frac{1}{x}[/tex] --- Objective function
Interval = [tex]\{x:x=1\}[/tex]
Step-by-step explanation:
Given
Represent the number with x
The required sum can be represented as:
[tex]x + \frac{1}{x}[/tex]
Hence, the objective function is:
[tex]S(x) = x + \frac{1}{x}[/tex]
To get the the interval, we start by differentiating w.r.t x
Using first principle, this gives:
[tex]S'(x) = 1 - \frac{1}{x^2}[/tex]
Equate S'(x) to 0 in order to solve for x
[tex]0 = 1 - \frac{1}{x^2}[/tex]
Subtract 1 from both sides
[tex]0 -1 = 1 -1 - \frac{1}{x^2}[/tex]
[tex]-1 = - \frac{1}{x^2}[/tex]
Multiply both sides by -1
[tex]1 = \frac{1}{x^2}[/tex]
Cross Multiply
[tex]x^2 * 1 = 1[/tex]
[tex]x^2 = 1[/tex]
Take positive square root of both sides because x is positive
[tex]\sqrt{x^2} = \sqrt{1[/tex]
[tex]x = 1[/tex]
Representing x using interval notation, we have
Interval = [tex]\{x:x=1\}[/tex]
To get the smallest sum, we substitute 1 for x in [tex]S(x) = x + \frac{1}{x}[/tex]
[tex]S(1) = 1 + \frac{1}{1}[/tex]
[tex]S(1) = 1 + 1[/tex]
[tex]S(1) = 2[/tex]
Hence, the smallest sum is 2

the ratio of males to females at camp is 5 to 4. if there are 40 males at the camp, how many females are there?
Answer:
32
Step-by-step explanation:
5:4 is the ratio. So 40/5 is 8. Therefore, you must multiply 4 by 8 to get the amount of females at the camp. Ergo, the answer is 32
Answer:
32
Step-by-step explanation:
You can solve this by setting up a proportion.
A 5 to 4 ratio is the same as [tex]\frac{5}{4}[/tex]
The proportion is [tex]\frac{5}{4}[/tex] = [tex]\frac{40}{x}[/tex]
By cross multiplying... you find that x (females) is equal to 32

Answer:
Line A slope = 3/2
Line B slope = 2
Step-by-step explanation:
We create the triangles they request for each line, as shown in the attached image, which we use to calculate the vertical change (height of the triangle) and horizontal change (base of the triangle). The height and base of the triangles (depicted in red and blue matching the color of the lines) have been highlighted for easy identification.
We estimate the vertical and horizontal changes, as well as the slope, for each line as shown below:
Line A:
vertical change = (6 - 3 ) = 3
horizontal change = (2 - 0) = 2
slope of line A = 3 / 2
Line B:
vertical change = (6 - 4) = 2
horizontal change = (3 - 2) = 1
slope = 2 / 1 = 2

What is the greatest common factor, and how is the distributive property used to factor it out from a polynomial?
Answer:
To factor a polynomial, identify the greatest common factor of the monomial terms, and then use the Distributive Property to rewrite the expression. Once a polynomial in a • b + a • c form has been rewritten as a(b + c), where a is the GCF, we say that the polynomial is in factored form.

Given the point and slope write the equation of the line (-4, 0); slope = 1/2
Answer:
The equation of the line will be:
[tex]y=\frac{1}{2}x+2[/tex]
Step-by-step explanation:
Given the point
(-4, 0)slope = m = 1/2As the equation of a line in slope-intercept form is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slopesubstituting the values m = 1/2 and the point (-4, 0)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-0=\frac{1}{2}\left(x-\left(-4\right)\right)[/tex]
[tex]y=\frac{1}{2}\left(x-\left(-4\right)\right)[/tex]
[tex]y=\frac{1}{2}\left(x+4\right)[/tex]
[tex]y=\frac{1}{2}x+\frac{4}{2}[/tex]
[tex]y=\frac{1}{2}x+2[/tex]
Therefore, the equation of the line will be:
[tex]y=\frac{1}{2}x+2[/tex]

Hi, this is apart of my homework assignment!
The Directions are, “Find the Percent Change. Specify an increase or a decrease.”
13. original amount: 25
amount of increase: 4
This is worth 12 pts!
Answer:
Percent Change is 16%
The change is increased.
Step-by-step explanation:
The original amount = 25
Amount increase = 4
We need to find percent increase
The formula used is: [tex]\frac{Amount \ increased}{Original \ Amount}*100[/tex]
Putting values in formula
[tex]Percent \ Change = \frac{Amount \ increased}{Original \ Amount}*100\\Percent \ Change =\frac{4}{25}*100\\Percent \ Change =16 \%[/tex]
So, Percent Change is 16%
The change is increased.
