the functions f and g are such that f(x) =3x-2 and g (x)=x-3
1 calculate the valve of g (-2)
ANSWER FAST!!!!!!!
Answer:
The value of g(-2) = -5
Step-by-step explanation:
Explanation:-
Given functions are f (x) = 3 x - 2 and g(x) = x-3
Given g (x) = x-3
Put x = -2 in g (x) = x-3
⇒ g ( -2 ) = - 2 -3 = -5
The value of g(-2) = -5

Answer:
for the first picture, she cleans 30 windows
the second picture is 52/100 :)
Answer:
It's B for the first one.
For the second one, it is C
Step-by-step explanation:
30 * 0.3 = 9
So 30% of 30 is 9. She did 9 windows.
0.52 = 52/100
It's 52/100 because 0.52 = 52%. 52% then equals 52/100.
52/100 = 13/25
So the answer is 13/25
One evening, 1255 people went to the movies to see Gone with the wind. The box office receipts totaled to 12,295. The price of admission for adults is $10.00 and for children, it is $7.00. Write an equation for how many people went to see the movie. Write an equation for the amount of money made at the box office. How many of each type of ticket did they sell (adult and children)?
Answer:
Number of adult tickets sold = 1170
Number of children tickets sold = 85
Step-by-step explanation:
Let,
x be the number of adult tickets sold
y be the number of child tickets sold
According to given statement;
x+y = 1255 Eqn 1
10x+7y=12295 Eqn 2
Multiplying Eqn 1 by 10
10(x+y=1255)
10x+10y=12550 Eqn 3
Subtracting Eqn 2 from Eqn 3
(10x+10y)-(10x+7y) = 12550 - 12295
10x+10y-10x-7y= 255
3y = 255
Dividing both sides by 3
[tex]\frac{3y}{3}=\frac{255}{3}\\y=85[/tex]
Putting y=85 in Eqn 1
x+85 = 1255
x = 1255-85
x = 1170
Hence,
Number of adult tickets sold = 1170
Number of children tickets sold = 85
Look at this triangle . Work out the length of AB . One of angles is 4 and other is 11
Answer:

plzzzz help meeeeeeeeeeeeeee
Answer:
Step-by-step explanation:
we have the set
[tex]3m+4n = 2\\\\5m-4n = 14[/tex]
add them both
[tex](3m+4n)+(5m-4n) = 2+14\\\\(3m+5m)+(4n-4n) = 16\\\\8m=16\\\\m = \frac{16}{8}\\\\m = 2[/tex]
now plug in m = 2 in equation 1 (it could aso be equation 2)
[tex]3m+4n = 2\\\\3(2)+4n = 2\\\\6+4n = 2\\\\4n = 2-6\\\\4n = -4\\\\n = -1[/tex]
so the solution is
m = 2
n = -1

Answer:
The values of [tex]x[/tex] so that [tex]y = \csc x[/tex] have vertical asymptotes are [tex]-2\pi[/tex], [tex]-\pi[/tex], [tex]0[/tex], [tex]\pi[/tex], [tex]2\pi[/tex].
Step-by-step explanation:
The function cosecant is the reciprocal of the function sine and vertical asymptotes are located at values of [tex]x[/tex] so that function cosecant becomes undefined, that is, when function sine is zero, whose periodicity is [tex]\pi[/tex]. Then, the vertical asymptotes associated with function cosecant are located in the values of [tex]x[/tex] of the form:
[tex]x = 0\pm \pi\cdot i[/tex], [tex]\forall \,i\in \mathbb{N}_{O}[/tex]
In other words, the values of [tex]x[/tex] so that [tex]y = \csc x[/tex] have vertical asymptotes are [tex]-2\pi[/tex], [tex]-\pi[/tex], [tex]0[/tex], [tex]\pi[/tex], [tex]2\pi[/tex].
What is the value for x in the diagram? Rounded to the tenth
Answer:
26.2
Step-by-step explanation:
Pythagoras theorem
Answer:
x ≈ 10,54 units
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 17² = 20²
x² + 289 = 400 ( subtract 289 from both sides )
x² = 111 ( take the square root of both sides )
x = [tex]\sqrt{111}[/tex] ≈ 10.54 ( to 2 dec. places )

Four points partition the directed line segment from A to B. • Point P partitions the directed line segment from A to B into a 3:4 ratio. • Point Q partitions the directed line segment from A to B into a 4:3 ratio. • Point R partitions the directed line segment from A to B into a 2:5 ratio. • Point S partitions the directed line segment from A to B into a 5:2 ratio. A number line has points A and B. A line is drawn from point A to point B. Which point will lie closest to B? P Q R S
Answer:
S is closest to B.
Step-by-step explanation:
Given a directed line segment from point A to B.
Point P divides the line A to B in a ratio 3:4.
Point Q divides the line A to B in a ratio 4:3.
Point R divides the line A to B in a ratio 2:5.
Point S divides the line A to B in a ratio 5:2.
To find:
The point which is closest to the point B.
Solution:
Here, to find the point closest to B we need to find the distances PB, QB, RB and SB.
We can see the sum of ratio 3:4, 4:3, 2:5 and 5:2 is 7.
Let the distance between A and B be 7 units.
Now, the distances can be found easily.
[tex]PB = \dfrac{4}{7}\times 7 = 4\ units[/tex]
[tex]QB = \dfrac{3}{7}\times 7 = 3\ units[/tex]
[tex]RB = \dfrac{5}{7}\times 7 = 5\ units[/tex]
[tex]SB = \dfrac{2}{7}\times 7 = 2\ units[/tex]
The point which has the minimum distance from point B, will be nearest to B.
We can clearly observe that SB is the minimum distance.
Therefore, S is closest to B.
The closest point to point B on the line AB is point S
The ratios are given as:
P = 3 : 4
Q = 4 : 3
R = 2 : 5
S = 5 : 2
Given that the point is from A to B, the first ratio proportion represents the position of each point between A and B
So, we remove the second ratio proportion of the above ratios
P = 3
Q = 4
R = 2
S = 5
The point with the highest value is S i.e. 5
Hence, point S is the closest to point B

(2 marks)
b Solve 4x + 4 = 28
(2 marks)
c Work out the length of BD.
(2 marks)
Answer:
The answer is below
Step-by-step explanation:
The line segment addition postulate states that for a line segment AC, another point B lies on AC if the below equation is satisfied:
AB + BC = BC
a) From the question, since point B and C lies on AD, then:
AD= AB + BC + CD
Substituting:
28 = (x) + (x + 5) + (2x - 1)
collecting like terms:
x + x + 2x + 5 - 1 = 28
Simplifying:
4x + 4 = 28
b) Simplifying the equation:
4x + 4 = 28
subtract 4 from both sides:
4x + 4 - 4 = 28 - 4
4x = 24
Divide through by 4:
4x / 4 = 24 / 4
x = 6
c) Also, BD = BC + CD
Hence:
BD = (x + 5) + (2x - 1)
x + 2x + 5 - 1 = BD
3x + 4 = BD
substitute value of x:
3(6) + 4 = BD
18 + 4 = BD
BD = 22

A fruit company sells two types of boxes large and small. A delivery of two large boxes and three small boxes has a total weight of 47 kilograms. A delivery of six large boxes in 5 small boxes has a total weight of 115 kg. How much does each type of box weigh?
Answer:
the large box weight is 6.50 kg and the small box weight is 13.75 kg
Step-by-step explanation:
The computation of each type of box weight is as follows:
Let us assume the large box be x
And, the small box be y
So,
2x + 3y = 47.......(i)
6x + 5y = 115........(ii)
Multiply by 3 in equation 1
6x + 9y = 141
6x + 5y = 115
Now subtract the last equation from the above one
4y = 26
y = 6.50
For x, it would be
2x+ 3(6.50) = 47
2x + 19.5 = 47
2x = 47 - 19.50
2x = 27.50
x = 13.75
Hence, the large box weight is 6.50 kg and the small box weight is 13.75 kg

The width of the rectangle is 5x-4. The length of the rectangle is 5
What is the simplified expression for the area of the rectangle?
Answer:
The area of the rectangle A = 25x² - 20x
Step-by-step explanation:
Given
The width of the rectangle = w = 5x - 4
The length of a rectangle = l = 5x
To determine
The area of the rectangle = ?
Using the Formula to determine the area of the rectangle
[tex]A = wl[/tex]
substitute w = 5x - 4 and l = 5x in the formula
[tex]A = (5x-4) (5x)[/tex]
Apply distributive law: a(b-c) = ab - ac
[tex]=\left(5x\right)\cdot \:5x-\left(5x\right)\cdot \:4[/tex]
[tex]=5x\left(5x\right)-4\left(5x\right)[/tex]
as 5x(5x) = 25x² and 4(5x) = 20x, so
[tex]=25x^2-20x[/tex]
Therefore, the area of the rectangle A = 25x² - 20x
