coordinates of the final image of point under this composition of transformations?

help please

I tried solving the problem and it didn't make sense until assuming that 22540.75 was a typo for 2540.75.

Answer:

2540.75 = 6.25x + 5.25y

435 = x + y

x = number of adult tickets

y = number of student and senior tickets

Question is asking to find x

- - - - - - - - - - - - - - - - - -

435 = x + y

2283.75 = 5.25x + 5.25y

Elimination method:

2540.75 = 6.25x + 5.25y

-(2283.75 = 5.25x + 5.25y)

257 = x

257 full priced tickets were sold.

Please mark for Brainliest!!  :D Thank you!!

For any questions, please comment!!

Answer:

Full tickets sold were 257 in count and discounted tickets were 178.

Step-by-step explanation:

Let the full tickets be = f

Let the discounted tickets be = d

Total tickets sold = 435

This can be written as :

[tex]f+d=435[/tex] or[tex]f=435-d[/tex]    .....(1)

The full price of a ticket is $6.25 and discount price is $5.25 and total earning is $2540.75.

In equation form, it can be written as :

[tex]6.25f+5.25d=2540.75[/tex]    ....(2)

Substituting the value of f in (2)

[tex]6.25(435-d)+5.25d=2540.75[/tex]  

[tex]2718.75-6.25d+5.25d=2540.75[/tex]

[tex]-1d=-178[/tex]

so , d = 178

And[tex]f+d=435[/tex]

So,[tex]f=435-178=257[/tex]

Hence, full tickets sold were 257 in count and discounted tickets were 178.

Answer:

-4x^2-6x+6

(third choice)

Step-by-step explanation:

To do f(x)-g(x) we must insert the expression for f(x) and g(x) into this:

This will give us:

(8x^2-2x+3)

-(12x^2+4x-3)

--------------------

-4x^2-6x+6

Horizontally if you prefer:

(8x^2-2x+3)-(12x^2+4x-3)

Distribute and get rid of paranthesis:

8x^2-2x+3-12x^2-4x+3

Pair up like terms:

8x^2-12x^2-2x-4x+3+3

Combine the like terms:

-4x^2-6x+6

Answer:

h(x) =  -4x^2 - 6x + 6

Step-by-step explanation:

f(x) - g(x)

=  8x^2 - 2x + 3 - (12x^2 + 4x - 3)    (Note the parentheses around g(x))

Distributing the negative over the parentheses:

= 8x^2 - 2x + 3 - 12x^2 - 4x + 3

= -4x^2 - 6x + 6 = h(x).

Answer:

Step-by-step explanation:

It's a right triangle.

The formula of an area of a right triangle:

[tex]A=\dfrac{ab}{2}[/tex]

a, b - legs

Find x-intercept and y-intercept of a line 4x + 5y = 20.

x-intercept (y = 0):

4x + 5(0) = 20

4x + 0 = 20

4x = 20     divide both sides by 4

x = 5

y-intercept (x = 0):

4(0) + 5y = 20

0 + 5y = 20

5y = 20      divide both sides by 5

y = 4

Therefore the legs are a = 5, b = 4.

Substitute:

[tex]A=\dfrac{(5)(4)}{2}=\dfrac{20}{2}=10[/tex]

Look at the picture.

Answer: Triangle

Answer:

If there are 5 persons and at a time only 3 can be arranged, the total number of arrangements is 60

Option C is correct

Step-by-step explanation:

There are 5 persons and at a time only 3 can be arranged.

The total number of arrangements = nPr = n!/(n-r)!

Here n = 5 and r = 3

nPr = n!/(n-r)!

nPr = 5!(5-3)!

nPr = 5!/2!

nPr = 5*4*3*2!/2!

nPr = 5*4*3

nPr = 60

So, if there are 5 persons and at a time only 3 can be arranged, the total number of arrangements is 60

Option C is correct.

Answer:

center ( -5 , 7).

Step-by-step explanation:

Given  : If the equation of a circle is (x + 5)² + (y - 7)² = 36.

To find : Find its center .

Solution : We have given (x + 5)² + (y - 7)² = 36.

Standard equation of circle : (x – h)² + (y – k)² = r².

Where, (h ,k) = center , r =  radius .

On comparing (x + 5)² + (y - 7)² = 36.

h = -5 , k = 7

So, the center ( -5 , 7).

Therefore, center ( -5 , 7).

Answer:

v=26.41 m/s

Step-by-step explanation:

From the Newtons laws of motions, we sew that x= (2v₁²sin∅os∅)/g where x is the horizontal distance v is the initial speed and ∅ is the launch angle.

From trigonometry we see that 2 sin∅cos∅=sin 2∅

Therefore,  x=(v²sin2∅)/g

x=22m

∅=9°

g=9.8m/s²

22m=v²×sin(2×9)/(9.8m/s²)

v²=(22×9.8)/(sin 18)

v²=697.696

v=√697.696

v=26.41 m/s

Answer:

y/2

Step-by-step explanation:

x+3=y+2

------  --------

3          2

Using cross products

2(x+3) = 3(y+2)

Distribute

2x+6 = 3y+6

Subtract 6 from each side

2x+6-6 = 3y+6-6

2x= 3y

Divide each side by 2

2x/2 = 3y/2

x = 3/2 y

We want to find x/3

Divide each side by 3

x/3 = 3/2 y * 1/3

x/3 = 1/2 y

Answer:

your answer is "18"

Step-by-step explanation:

Formula is:

A= 1/2 (A+B) X H

A = 1/2 (CD + CF) X H

A = 1/2 (5+6) X 3

A = 16.5 CM SQUARED

Hope this is right!

Since ABCF is a rectangle, angle AFC is a right angle. Angle CFE is also a right angle. Since angle DCF is also a right angle, then trapezium CDEF has parallel sides CD and EF.

BC + CD = BD

4 cm + CD = 9 cm

CD = 5 cm

EF = 3 cm

Sides CD and EF are the parallel bases of the trapezium. Side CF is the height of the trapezium.

area of trapezium = (base1 + base2)h/2

area = (5 cm + 3 cm)(6 cm)/2

area = (8 cm)(6 cm)/2

area = 24 cm^2

To solve the system of equations, we can use the method of substitution. However, when we substitute the expression for x in the second equation, we get an equation that is not true, indicating that the system has no solution.

To solve the system of equations given by 5x - 2y = -6 and 15x - 6y = 6, we can use the method of substitution. First, we can solve one of the equations for either variable, then substitute that expression into the other equation to solve for the other variable. Let's solve the first equation for x:

5x - 2y = -6

5x = 2y - 6

x = (2y - 6)/5

Now, substitute this expression for x in the second equation:

15((2y - 6)/5) - 6y = 6

6y - 18 - 6y = 6

-18 = 6

This leads to the equation -18 = 6, which is not true. Therefore, the system of equations has no solution. So, the correct answer is C. No solution.

Step-by-step answer:

If x and y both go by equal steps, not necessarily equal steps between x and y, the relation is linear

Here, x goes by steps of 6 (1,7,13,19) and y goes by steps of 3 (4,7,10,13), therefore the relation is linear.

To find the equation passing through all the points, we find first the slope, which is steps in y divided by steps in x, or

slope, m = 3/6 = 1/2

Next, we take any point from the data, say, P0=(x0,y0)=(1,4), and substitute in the point-slope form of the equation

y-y0 = m(x-x0)...........................(1)

since x0=1, y0=4, and m=1/2, we get the equation

y-4 = (1/2)*(x-1) .........................(2)

Simplify (2) to get the slope-intercept form of the linear relation:

y = (1/2)x + 7/2 ........................(3)

Finally, we check the results of the y-values for given values of x, using the relation given in equation (3):

y(1) = 4

y(2)=7

y(3)=10

y(4)=13

all of which correspond exactly to original data, so the equation of the linear relation is correct.

Answer:

|-5| is the answer.

Step-by-step explanation:

The opposite of 5 is -5. The absolute value of a number is always positive (e.g: |-10| = 10 because the negative sign is inside the absolute value bars).

-|5| and -|-5| both equal -5 because there is a negative sign outside of the bars. Since |-5| has a negative sign inside the bars, it equals 5.

Answer:

The investment be worth $23328 after 11 years.

Step-by-step explanation:

It is given that the annual growth reflects a geometric sequence.

An initial investment of $3 is worth $108 after 5 years.

It means the initial value of first term of the gp, a₁ = 3

The 5th term of the gp, a₅ = 108

The nth term of a gp is

[tex]a_n=ar^{n-1}[/tex]              .... (1)

where, a is first term and r is common ratio.

The 5th term of the gp is

[tex]a_5=ar^{5-1}[/tex]

From the given information it is clear that the 5th term of the gp is 108. Substitute a₅ = 108 and a=3.

[tex]108=(3)r^{4}[/tex]

Divide both sides by 3.

[tex]\frac{108}{3}=r^{4}[/tex]

[tex]36=r^{4}[/tex]

Taking fourth root on both the sides.

[tex]\sqrt{6}=r[/tex]

Substitute r=√6, a=3 and n=11 to find the investment worth after 11 years.

[tex]a_{11}=(3)(\sqrt{6})^{11-1}[/tex]

[tex]a_{11}=3(\sqrt{6})^{10}[/tex]

[tex]a_{11}=23328[/tex]

Therefore the investment worth $23328 after 11 years.

Final answer:

The value of the discriminant of the quadratic equation -2x² - 8x + 8 is 128. The positive discriminant suggests that the equation has two distinct real roots.

Explanation:

The discriminant of a quadratic equation can be calculated using the formula D = b² - 4ac, where a, b, and c are the coefficients of the quadratic equation in the form ax² + bx + c = 0.

In the given quadratic equation -2x² - 8x + 8, a = -2, b = -8, and c = 8. Substituting these values into the discriminant formula:

D = (-8)² - 4(-2)(8) = 64 - (-64) = 128.

The value of the discriminant is 128. The discriminant value can provide information about the nature of the roots of the quadratic equation. If the discriminant is positive (greater than 0), then the equation has two distinct real roots. If the discriminant is 0, then the equation has one real root (a repeated root). If the discriminant is negative, then the equation has no real roots.

Answer:

Step-by-step explanation:

first you need to find out hour much the secretary gets paid an hour.  So you will divide $262.50 by 35 hours

262.50 / 35 = 7.50

so we know that she worked over time of 6 hours and that will be time and half

to figure out how much for time and a half.  We are going to divide her hourly rate by 2.  

7.50 / 2 = 3.75

then to find out how much she made for that 6 hours we will add

7.50 + 3.75 = 11.25

to get the amount for over time on Saturday we will multiply

11.25 x 6 = 67.50

Now for the double time we will double her pay so will add

7.50 + 7.50 = 15

so then we are going to multiply to get your pay for the 4 hours overtime

15(4) = $60

Now to find the total amount we are going to add all of our totals together.  

262.50 + 67.50 + 60 = 390.

Hi there!

The best way to approach this problem is Soh Cah Toa.

In this case you can use sine. sine is opposite over hypotenuse.

so sin(17)= b/15

then to solve for b you multiply 15 on both sides to get 4.4

Answer:

Step-by-step explanation:

This question is an application of the sine law

Equation

b/sin(B) = c / Sin(C)

Givens

b = ????

B = 17

c = 15

C = 140

Solution

Keep in mind that this may not work.

b/sin(17) =   15 / sin(140)                          Multiply both sides by sin(17)

b = 15*sin(17)/sin(140)

b = 15*0.2924/0.6428

b = 6.8233

Your question is incomplete and lacks the table. Please check below for the full content.

A group of students is collecting books to add to their library. The table shows the number of books in the library after 1, 3, and 5 days. If the relationship between days and books continues to be linear, which ordered pairs could appear in the table? Check all that apply.

(0, 8)

(2, 23)

(4, 32)

(6, 48)

(7, 48)

The missing table is given below.

The correct options are option 2:(2,23) and 5:(7,48) The ordered pair (2,23),(7,48) will appear in the table.

The equation where highest degree of the variable used in the equation is 1 is called linear equation. Foe example ax+by+c=0

Here given the relationship between days and books is linear.

From the table, it clear that In day 1 the book collected is 18.

in day 3 book collected is 28.

x₁=1,y₁=18

x₂=3,y₂=28

The linear equation will be

(y-y₁)/(x-x₁)=(y₂-y₁)/(x₂-x₁)

⇒(y-18)/(x-1)=(28-18)/(3-1)

⇒(y-18)/(x-1)=10/2

⇒(y-18)/(x-1)=5

⇒y-18=5(x-1)

⇒y-18=5x-5

⇒y=5x-5+18

⇒y=5x+13

So the linear equation will be y=5x+13

By ckecking every option,

1. (0, 8)-  y=5*0+13=13≠8  Option 1 is incorrect.

2. (2,23)-  y=5*2+13=23    Option 2 is correct.

3. (4,32)-   y=5*4+13=33≠32   Option 3 is incorrect.

4.(6,48)-   y=5*6+13=43≠48     Option 4 is incorrect.

5. (7,48)    y=5*7+13=48   Option 5 is correct.

Therefore the correct options are option 2 and 5 i.e. The ordered pair (2,23) , (7,48) will appear in the table.

f(x - n) - shift a graph of f(x) n units to the right

=============================================

We have

[tex]f(x)=x^2,\ g(x)=x^2+(-8x)+7[/tex]

Convert the equation of g(x) to the vertex formula:

[tex]y=a(x-h)^2+k[/tex]

[tex]g(x)=x^2+(-8x)+7\\\\g(x0=x^2-2(x)(4)+7\\\\g(x)=\underbrace{x^2-2(x)(4)+4^2}-4^2+7\qquad\text{use}\ (a-b)^2=a^2-2ab+b^2\\\\g(x)=(x-4)^2+7=f(x-4)+7\\\\\text{shift the graph of f(x) 4 units to the right and 7 units up}[/tex]

Answer:

p(z<0.42) = 0.6628

Step-by-step explanation:

A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. That is to say:

μ = 0

σ² = 1

Using a calculator, we find that:

p(z<0.42) = 0.6628 (See picture attached)

Answer:

0.66276.

Step-by-step explanation:

We are asked to find the approximate value of p(z<0.42) for a standard normal distribution.

Our given expression means the probability of getting a z-score less than 0.42.

We need to find the probability of getting the area corresponding to a z-score less than 0.42 under normal distribution curve.

We will normal distribution table to solve our given problem.

[tex]p(z<0.42)=0.66276[/tex]

Therefore, the approximate value of our given expression would be 0.66276.
