Find the measure of angle R

Answer:

number of guest tickets, g, is 100 tickets

number of student tickets, s, is 125 tickets

Step-by-step explanation:

Given;

total number of tickets sold, t = 225 tickets

cost of each guest ticket,  = $5.5

cost of each student ticket, = $3.5

total cost of the tickets, Tc = $987.5

number of guest tickets = g

number of student tickets, = s

g(5.5) + s(3.5) = 987.5 ------- (1)

g + s = 225 ----------- (2)

From equation (2); s = 225 - g

Substitute the value of g in equation (1)

5.5g + 3.5(225 - g) = 987.5

5.5g + 787.5 - 3.5g = 987.5

5.5g - 3.5g = 987.5 - 787.5

2g = 200

g = 200 / 2

g = 100 tickets

Then, s = 225 - g

s = 225 - 100

s = 125 tickets

Answer:

graph attached

Step-by-step explanation:

12x+9y=-36

(12x+9y)/3=-36/3

4x+3y=-12

2 functions has the same value, they are identical line

6x-8y-x+3y

= (6x-x)+(-8y+3y)

= 5x+(-5y)

=5x-5y

Answer:

5x-5y

Step-by-step explanation:

Equation;

6x-8y-x+3y(Group like terms)

Which is going to be;

6x-x-8y+3y

Then you proceed to simplify;

5x-5y

This is the final answer

Step-by-step explanation:

there are total of 71 bills of varying denominations in the bag

you need to select a bill that is $10 or more to cover your $6 expense; therefore, P($ ≥ 10) = 3 + 7 + 3 / 71  or 13 /71, about 18%

7. -3x²+9x-4

8. 3

9. 6a+15

Step-by-step explanation:

you will subtract/add the numbers with the same variables and exponent.

ex. (number 6) 7b²+ b²= 8b²

5b= 5b 8b²+5b-4

1-5= -4

(plus 5b because it didnt come out to a negative) if you have any questions, say in the comments and ill try my best to help

Answer:

y = 33 / 15 = 11 /5

Step-by-step explanation:

subtract 3 from both sides,

15y = 33

divide 15 from both sides

y = 33/15

simplify ( divide top and bottom by 3)

y = 11/5

[tex]\boxed{\pink{\tt\longmapsto The \ nth \ term \ of \ the \ sequence\ is \ given \ by \ frac{1}{n}}}[/tex]

A sequence is given to us is , and we need to find expression for nth term of the sequence. The given sequence is ,

[tex]\bf 1 , \dfrac{1}{2},\dfrac{1}{3},\dfrac{1}{4},\dfrac{1}{5},\dfrac{1}{6}[/tex]

When we flip the numbers , we can clearly see that the number are in Harmonic Progression.

That is when we flip the numbers they are found to be in Arithmetic Progression .

And nth term of an Harmonic Progression is :-

[tex]\boxed{\purple{\bf T_{(Harmonic \ Progression)} = \dfrac{1}{a+(n-1)d}}}[/tex]

Hence here

Substituting the respective values,

[tex]\bf\implies T_{n}= \dfrac{1}{a+(n-1)d} \\\\\bf\implies T_{n} = \dfrac{1}{1+(n-1)1}\\\\\bf\implies T_n = \dfrac{1}{1+n-1}\\\\\bf\implies\boxed{\red{\bf T_{n}=\dfrac{1}{n}}}[/tex]

Answer: 1

Step-by-step explanation:

Answer:

The equation of the line that is parallel to the linear graph of y = 2x - 1 and passes through the point (-1, 1) will be:

[tex]y=2x+3[/tex]

Hence, option D is true.

Step-by-step explanation:

We know that linear function can be represented using the slope-intercept formula

y = mx+b

where m is the slope and b is the y-intercept

Given the equation

y = 2x - 1

comparing with the slope-intercept form y = mx+b

Hence, the slope of the line y = 2x - 1 is: m = 2

We know that the parallel lines have the same slopes.

Thus, the slope of the equation of the line that is parallel to the linear graph of y = 2x - 1 will also be: 2

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values of the slope = 2 and the point (-1, 1)

[tex]y-1=2\left(x-\left(-1\right)\right)[/tex]

[tex]y-1=2\left(x+1\right)[/tex]

Add 1 to both sides

[tex]y-1+1=2\left(x+1\right)+1[/tex]

Simplify

[tex]y=2x+3[/tex]

Therefore, the equation of the line that is parallel to the linear graph of y = 2x - 1 and passes through the point (-1, 1) will be:

[tex]y=2x+3[/tex]

Hence, option D is true.

Answer:

Line 1 and line 2 are neither parallel nor perpendicular

Line 1 and 3 are perpendicular to each other

Line 2 and line 3 are neither parallel nor perpendicular

Step-by-step explanation

Given the equations of the line

Line 1: 4x-6y= -6

Line 2: -3y=2x+5

Line 3: y= -3/2x-5

Before we can know which line is parallel or perpendicular to each other, we need to find their slope first

For line 1:

4x-6y= -6

Write in standard form y = mx+c

-6y = -4x - 6

Divide through by -6

-6y/-6 = -4x/-6 - 6/-6

y = 2/3 x + 1

The slope of line  1 is 2/3

For line 2:

-3y=2x+5

Divide through by -3

-3y/-3 =2x/-3 + 5/-3

y = -2/3 x - 5/3

The slope of this line is -2/3

For line 3:

y= -3/2x-5

this is already written in standard format. The slope of this line is -3/2

Note that for two lines to be parallel, they must have the same slope

For two lines to be perpendicular, the product of their slope must be -1

For line 1 and line2, we can see that their slope are not the same and the product is not -1, hence both lines are neither parallel nor perpendicular

For line 1 and line 3, we can see that their slope are not the same but the product of their slope is -1 (2/3 * -3/2 = -1), hence both lines are perpendicular.

For line 2 and line 3, we can see that their slope are not the same and the product is not -1, hence both lines are neither parallel nor perpendicular
