Answer:
Step-by-step explanation:
9x times -1 =-9x
-9x-18 divide
(4+5=)9
divide 18 by the denominator 9 and get
-9x-2
/1
since anything pretty much divided by 1 remains the same this is simplified to
-9x-2 and since you dont know x's variable this is its simplifed form
Answer:
-9x-2
Step-by-step explanation:
[tex]9x(-1)-18/(4+5)[/tex]
Multiply 9x and -1
[tex]-9x-18/(4+5)[/tex]
Add 4 and 5
[tex]-9x-18/9[/tex]
Divide 18 and 9
[tex]-9x-2[/tex]

That's pretty cool you know.
Answer:
thats cool. hope he getting paid good
Step-by-step explanation:
The price of a 7-minute phone call is $2.45. What is the price of an 18 -minute phone call?
[tex]\boxed{\boxed{\pink{\bf \leadsto The \ price \ of \ a\ 18 \ min \ call \ is \ \$ \ . }}}[/tex]
Step-by-step explanation:According to Question ,The price of a 7-minute phone call is $2.45 . And we need to find the price of a18 minute phone call . So we will use unitary method here ,
[tex]\implies\bf Cost \ of \ 7 \ min. \ phone \ call \ is\ \$ \ 2.45 . \\\\\implies \bf Cost \ of \ 1 \ min. \ phone \ call \ will \ be \ \dfrac{\$ 2.45}{7} \\\\\implies \bf Cost \ of \ 18 \ min. \ phone \ call \ will \ be \ \dfrac{\$ 2.45}{7} \times 18 = \red{\$ 6.3 } [/tex]
Hence the cost of 18 minutes call is $ 6.3 .Here it was a case of direct proportion in which if two things are directly proportional to each other. If one thing thing increases then the value of second also increases. Here if the time increases then the cost also increases.
8r-5>75. helpppppppp
Answer and Step-by-step explanation:
In this inequality, we are solving for r. Just think of this as a normal equation, and worry about the sign at the end.
First, add 5 to both sides.
8r > 80
Now divide by 8 to both sides.
r > 10
So, r is greater than 10.
[ If the inequality had a negative number being divided, then the sign would flip.
For example:
-2x > 4
To solve this one, you would divide by -2 to both sides. Then, you would flip the sign.
x < 2 ]

The Population of a town was
12000 in 1980 and 16000 in 1990.
What was the percent increase in
the population of the town during
this period?
[2011]
Answer:
33.3%
Step-by-step explanation:
Step one:
given data
Initial population (1980)= 12000
Final population(1990)= 16000
change in population= 16000-12000= 4000
Step two:
% increase= change in population/initail population *100
%increase= 4000/12000*100
%increase= 0.333*100
% increase= 33.3%

The exponential function f(x) = 2x undergoes two transformations to
g(x) = 1/3• 2x – 7. How does the graph change? Select all that apply.
A. It is shifted right.
B. It is shifted down.
C. It is flipped over the x-axis.
D. It is vertically compressed.
E. It is vertically stretched.
Answer:
Shifting down.
Vertically compressed
Step-by-step explanation:
Given
[tex]f(x) = 2^x[/tex]
[tex]g(x) = \frac{1}{3}(2^x - 7)[/tex]
Required
Determine the translation from f(x) to g(x)
The first translation from f(x) towards g(x) is:
[tex]f(x) = 2^x[/tex]
[tex]f'(x) = 2^x - 7[/tex]
This is derived by:
[tex]f'(x) = f(x) - b[/tex]
Where
[tex]b = 7[/tex]
Notice that, in the above, b (i.e. 7) was subtracted from f(x), this implies that the function shifted down
The next translation that resulted in g(x) is:
[tex]g(x) = \frac{1}{3}(2^x - 7)[/tex]
This is derived by:
[tex]g(x) = a.f'(x)[/tex]
By comparison:
[tex]a = \frac{1}{3}[/tex]
Since the value of a is less than 1, then f'(x) is vertically compressed to give g(x).
Hence, the transformations that apply from f(x) to g(x) are:
Shifting down. Vertically compressedAnswer:

Write an equation of the line with the given slope and y-intercept:
M = 2, B = - 3/4
a. y = 2x + 3/4
b. y = 2x + 3/4
C. y = 2x - 3/4
d. y = 2x + 3/4
Please select the best answer from the choices provided
Answer: C
Step-by-step explanation: Since we know both the slope and the y-intercept we can plug them into Slope-Intercept form. Slope-Intercept form is y=mx+b
Since m = 2 and b = -3/4 all we have to do is replace both m and b in the form and that would be the answer. y = 2x-3/4

I need help finding the value
Answer:
17
Step-by-step explanation:
First, we notice that the triangle is isosceles . (In case you didn't know, the two tick marks on the sides of the triangle signify that they are congruent and have the same length.) Since the triangle is isosceles, we can apply the Base Angles Theorem.
The Base Angle Theorem states that the two angles opposite of the two congruent sides are also congruent. In this case, we can say that, because the angle measuring 29° and the third(top) angle are opposite to the two congruent sides, those two angles are congruent. Therefore, the third angle measures 29° as well.
Now that we know this, we can write the following equation:
29°+29°+(11x-65)° = 180.
Solving this equation, we have x = 17.

Answer:
These triangles cannot be proven congruent
Step-by-step explanation:
If all sides and angles of a triangle is congruent to the corresponding sides and angles of another triangle, both triangles are congruent to each other.
This means, they have the same shape and size.
Invariably, knowing just the angles of two triangles are congruent to each other, is not enough to prove that the two triangles are congruent to each other.
Two triangles might have the same angle measure but different size lengths. This means they can have the same shape but different size.
With the information given in the diagram, we can only say that both triangles are similar to each other. However, we cannot prove they are congruent to each other.

which of the following best describes 4^2/3? a. sq root of 16, b. cube root of 4, c. sq root of four, d. cube root of 16
Answer: D) cube root of 16
================================================
Explanation:
The rule we use is
[tex]x^{m/n} = \sqrt[n]{x^m}[/tex]
In this case, x = 4, m = 2 and n = 3.
So,
[tex]x^{m/n} = \sqrt[n]{x^m}\\\\\\4^{2/3} = \sqrt[3]{4^2}\\\\\\4^{2/3} = \sqrt[3]{16}\\\\\\[/tex]
Showing that the original expression turns into the cube root of 16.

What is the slope of a line through (1, 3) and (-2, 2)?
Answer:
The slope of the line is [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The Slope of a Line
Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
It's given the points (1,3) and (-2,2). Let's calculate the slope:
[tex]\displaystyle m=\frac{2-3}{-2-1}[/tex]
Calculating:
[tex]\displaystyle m=\frac{-1}{-3}[/tex]
[tex]\displaystyle m=\frac{1}{3}[/tex]
The slope of the line is [tex]\frac{1}{3}[/tex]
which equations are equivalent to a/b = c/d? choose more than one answer
Answer:
[tex]a d = bc[/tex]
[tex]da = cb[/tex]
[tex]bc = ad[/tex]
Step-by-step explanation:
Given
[tex]\frac{a}{b} = \frac{c}{d}[/tex]
Required
Choose equivalent expressions
First, cross multiply
[tex]a * d = b * c[/tex]
[tex]a d = bc[/tex]
The product: [tex]a * d = b * c[/tex] can also be rewritten as:
[tex]da = cb[/tex]
Apply symmetric property of inequality
[tex]a d = bc[/tex] becomes [tex]bc = ad[/tex]
and
[tex]da = cb[/tex] becomes [tex]cb = da[/tex]
A game of football with 11 players lasts for exactly 90 minutes. There are four substitutes that alternate equally. If each player plays for the same length of time, what is the duration? (A) 22.5 mins (B) 18 mins (C) 66 mins (D) none of these
Answer: (A) 22.5 mins
Step-by-step explanation:
Given data:
Duration of the match = 90mins.
Number of substitutes = 4.
Solution:
Since Each of the four (4) substitute players alternated equally, simply means each of the 4 players spent an equal amount of time on the football pitch.
= 90mins/4
= 22.5mins.
Each player spent 22.5minutes on the football pitch.
The division of total time distribute the same time for each substitutes player.
The duration for which each substitute player plays the game of football is 22.5 minutes.
What is division of time?Division of total time by the units of division provides the equal time for each unit.
Given information-
A game of football with 11 players lasts for exactly 90 minutes.
Total number of substitutes is 4.
All the players plays for the same length of time.
As there is total number of substitute players are 4 and the total time duration is 4.
Thus for each player to play same length of time, the time should be divided by the number of players. Therefore,
[tex]t=\dfrac{90}{4} \\t=22.5[/tex]
Hence the duration for which each substitute player plays the game of football is 22.5 minutes.
