3m-n=km-8, solve for m
Add n on both sides:
3m = km - 8 + n
Subtract km on both sides:
3m - km = n - 8
Factor the Left-Hand Side:
m(3 - k) = n - 8
Divide both sides by (3 - k):
m = (n - 8) / (3 - k)
Answer:
(8-n)/(k-3) =m
Step-by-step explanation:
3m-n=km-8
Subtract 3m from each side
3m -3m-n=km -3m-8
-n =km -3m-8
Add 8 to each side
8-n =km -3m-8+8
8-n =km -3m
Factor out m
8-n =m(k -3)
Divide by (k-3)
(8-n)/(k-3) =m(k -3)/( k-3)
(8-n)/(k-3) =m

What value(s) of x would make f(g(x)) and g(f(x)) commutative? x greater-than-or-equal-to 1 or x less-than-or-equal-to negative 1 Negative 1 less-than-or-equal-to x less-than-or-equal-to 1 any value of x no value of x
Answer:
Any value of x
Step-by-step explanation:
Given
[tex]f(x) = \sqrt{x^2 - 1}[/tex]
[tex]g(x) = \sqrt{x^2 + 1}[/tex]
Required
What value of x is [tex]f(g(x)) = g(f(x))[/tex]
Solving for f(g(x))
[tex]f(x) = \sqrt{x^2 - 1}[/tex]
[tex]f(g(x)) = \sqrt{(\sqrt{x^2 + 1})^2 - 1}[/tex]
Solve the inner square
[tex]f(g(x)) = \sqrt{(x^2 + 1 - 1}[/tex]
[tex]f(g(x)) = \sqrt{x^2 } }[/tex]
[tex]f(g(x)) = x[/tex]
Solving g(f(x))
[tex]g(x) = \sqrt{x^2 + 1}[/tex]
[tex]g(f(x)) = \sqrt{(\sqrt{x^2 - 1})^2 + 1}[/tex]
[tex]g(f(x)) = \sqrt{x^2 - 1 + 1}[/tex]
[tex]g(f(x)) = \sqrt{x^2 }[/tex]
[tex]g(f(x)) = x[/tex]
Equate f(g(x)) and g(f(x))
[tex]f(g(x)) = g(f(x))[/tex]

One angle of an octagon is 65º. The
others are equal to each other. Find them.
x = 145°
Step-by-step explanation:the sum of interior angles of octagon formula
S = (n - 2)×180°
n = 8
S = (8 - 2)×180°
S = 6×180°
S = 1080°
we have 1 angle = 65° & others are equal to each other
1080° - 65° = 7x
7x = 1015°
x = 1015° : 7
x = 145°

A man standing 24 feet from a building observes the angle of elevation of its top to be 38°. Find the height of the building to the nearest tenth.
Answer:
The height of the building is 18.8 feet to the nearest tenth
Step-by-step explanation:
Whenever an elevation problem is given the first step is to try to visualize a triangular path between the objects that are given in the problem.
In this case, we can form a triangular path between the man, the top of the building, and the ground.
The height of the building we are looking for will be the opposite side of the triangle because it is directly facing the angle: 38 degrees.
The distance 24 feet will be the adjacent side of the triangle because it is adjacent to that angle
We can use the Tan trigonometric relationship to find a relationship between the length of the sides of the triangle and the available angles.
[tex]tan 38 = height/24ft[/tex]
[tex]height = 24 \times tan38 = 18.75ft[/tex] approximately 18.8 ft

The perimeter of a pool is 150 m. the rectangle at the right is a scale drawing of the pool. The length of each square on the grid represents 1 cm. draw another scale drawing of the pool using the scale 25 m to 2 cm. Explain why your drawing is accurate.
Answer:
Step-by-step explanation:
From the given rectangle,
Length of the rectangle = 5 cm
Width of the rectangle = 10 cm
Ratio of length : width = 1 : 2
Perimeter of the rectangle = 2(l + b)= 150 cm
l + b = 75 -----(1)
Since, l : b = 1 : 2
[tex]\frac{l}{b}= \frac{1}{2}[/tex]
b = 2l ------(2)
From equations (1) and (2),
l + 2l = 75
3l = 75
l = 25 m
Width 'b' = 2(25) = 50 m
Now we have to draw a rectangle with a scale = 25 : 2
Therefore, Scale factor = [tex]\frac{25}{l}=\frac{25}{2}[/tex]
l = 2 cm
Similarly,
[tex]\frac{50}{w}=\frac{25}{2}[/tex]
w = 4 cm
Now we can draw a rectangle with length = 2 cm and width = 4 cm.

Find the sum of the positive integers less than 200 which are not multiples of 4 and 7
Answer:
[tex]12942[/tex] is the sum of positive integers between [tex]1[/tex] (inclusive) and [tex]199[/tex] (inclusive) that are not multiples of [tex]4[/tex] and not multiples [tex]7[/tex].
Step-by-step explanation:
For an arithmetic series with:
[tex]a_1[/tex] as the first term, [tex]a_n[/tex] as the last term, and[tex]d[/tex] as the common difference,there would be [tex]\displaystyle \left(\frac{a_n - a_1}{d} + 1\right)[/tex] terms, where as the sum would be [tex]\displaystyle \frac{1}{2}\, \displaystyle \underbrace{\left(\frac{a_n - a_1}{d} + 1\right)}_\text{number of terms}\, (a_1 + a_n)[/tex].
Positive integers between [tex]1[/tex] (inclusive) and [tex]199[/tex] (inclusive) include:
[tex]1,\, 2,\, \dots,\, 199[/tex].
The common difference of this arithmetic series is [tex]1[/tex]. There would be [tex](199 - 1) + 1 = 199[/tex] terms. The sum of these integers would thus be:
[tex]\begin{aligned}\frac{1}{2}\times ((199 - 1) + 1) \times (1 + 199) = 19900 \end{aligned}[/tex].
Similarly, positive integers between [tex]1[/tex] (inclusive) and [tex]199[/tex] (inclusive) that are multiples of [tex]4[/tex] include:
[tex]4,\, 8,\, \dots,\, 196[/tex].
The common difference of this arithmetic series is [tex]4[/tex]. There would be [tex](196 - 4) / 4 + 1 = 49[/tex] terms. The sum of these integers would thus be:
[tex]\begin{aligned}\frac{1}{2}\times 49 \times (4 + 196) = 4900 \end{aligned}[/tex]
Positive integers between [tex]1[/tex] (inclusive) and [tex]199[/tex] (inclusive) that are multiples of [tex]7[/tex] include:
[tex]7,\, 14,\, \dots,\, 196[/tex].
The common difference of this arithmetic series is [tex]7[/tex]. There would be [tex](196 - 7) / 7 + 1 = 28[/tex] terms. The sum of these integers would thus be:
[tex]\begin{aligned}\frac{1}{2}\times 28 \times (7 + 196) = 2842 \end{aligned}[/tex]
Positive integers between [tex]1[/tex] (inclusive) and [tex]199[/tex] (inclusive) that are multiples of [tex]28[/tex] (integers that are both multiples of [tex]4[/tex] and multiples of [tex]7[/tex]) include:
[tex]28,\, 56,\, \dots,\, 196[/tex].
The common difference of this arithmetic series is [tex]28[/tex]. There would be [tex](196 - 28) / 28 + 1 = 7[/tex] terms. The sum of these integers would thus be:
[tex]\begin{aligned}\frac{1}{2}\times 7 \times (28 + 196) = 784 \end{aligned}[/tex].
The requested sum will be equal to:
the sum of all integers from [tex]1[/tex] to [tex]199[/tex], minus the sum of all integer multiples of [tex]4[/tex] between [tex]1\![/tex] and [tex]199\![/tex], and the sum integer multiples of [tex]7[/tex] between [tex]1[/tex] and [tex]199[/tex], plus the sum of all integer multiples of [tex]28[/tex] between [tex]1[/tex] and [tex]199[/tex]- these numbers were subtracted twice in the previous step and should be added back to the sum once.That is:
[tex]19900 - 4900 - 2842 + 784 = 12942[/tex].

the scale from a square exercise mat in a gymnastic arena to a scale copy of the exercise mat is 8 m for every 2 in. The actual area of the exercise mat is 144m2. What are the dimensions of the mat on the scale copy?
Answer: 18 and 36
Step-by-step explanation:
The scale is 8m for every 2 in and the actual area is 144m2 so we need to covert that into inches. You divide 144 by 8 which = 18 and then multiply 18 x 2 which is equal to 36.

Maya is saving up to buy a new jacket. She already has $30 and can save an additional $10 per week using money from her after school job. How much total money would Maya have after 6 weeks of saving? Also, write an expression that represents the amount of money Maya would have saved in w w weeks.
Answer:
x = 6 weeks
Step-by-step explanation:
We'll let x represent the number of weeks it will take to save enough money. If she saves $11 each week, then in x weeks she will save 11x dollars.
Add this to the 107 she has already saved, and at the end of 11 weeks she will have 11x + 107 dollars.
We want the amount saved to be equal to the price of the bike, so our equation is
11x + 107 = 173
In a word problem, writing the equation is usually the hardest part. Now we solve the equation.
Subtract 107 from both sides to get
11x = 66
Divide both sides by 11 to get
x = 6 weeks

Elizabeth claims that the only square root of 36 is 6. Which statement below disproves Elizabeth’s claim? A) 6 is a factor of 36. B )36 has both even and odd factors. C) The square root of a whole number is sometimes a decimal value. D) The square root of a positive number can be a negative or positive value.
Answer:
D) The square root of a positive number can be a negative or positive value.
Step-by-step explanation:
36 is a perfect square, meaning that the square root of 36 is equivalent to an integer, 6, whereby, the integer 6, when multiplied by itself gives us the perfect square, 36.
i.e. 36 = 6*6 = 6²
√36 = √6² = 6
There are actually two possible square root of 36. That is -6.
Square of, -6², equivalently is -6 * -6 = 36.
Therefore, √36 = ±6.
So, her claim is wrong. 6 is not the only square root of 36.
Square root of 36 could be negative 6 or positive 6.
