The school that Alberto goes to is selling tickets to a fall musical. On the first day of ticket sales
the school sold 6 senior citizen tickets and 2 child tickets for a total of $96. The school took in
$120 on the second day by selling 6 senior citizen tickets and 4 child tickets. Find the price of a
senior citizen ticket and the price of a child ticket.
Answer:
The price of both tickets is $12 each
Step-by-step explanation:
System of Equations
Let's call:
x = price of a senior citizen ticket
y = price of a child ticket.
On the first day of ticket sales, the school sold 6 senior citizen tickets and 2 child tickets for $96. Setting up the first equation:
6x + 2y = 96
Dividing by 2:
3x + y = 48 [1]
On the second day, the school sold 6 senior citizen tickets and 4 child tickets for $120:
6x + 4y = 120
Dividing by 2:
3x + 2y = 60 [2]
Subtracting [2] and [1]:
2y - y = 60 - 48
y = 12
From [1]:
3x + 12 = 48
3x = 48 - 12 = 36
x = 36/3 = 12
x = 12
The price of both tickets is $12 each
(PLS HELP ITS EASY) which of the following is a solution to the system of equations shown below?
1 x=10 and y=21. 2x+3y=83
2 x=7 and y=23. y=2x+9
3 x= -4 and y=1
4 x=4 and y=25
Answer:
A solution of the system of equation given in the question is;
(2) x = 7 and y = 23
Step-by-step explanation:
The given system of equation are;
2·x + 3·y = 83...(1)
y = 2·x + 9...(2)
Substituting the value of y = 2·x + 9 from equation (2) into equation (1) gives;
2·x + 3·y = 2·x + 3 × (2·x + 9) = 83
∴ 2·x + 6·x + 27 = 83
8·x = 83 - 27 = 56
x = 56/8 = 7
x = 7
By substituting the value of x = 7 derived above into equation (1), we have;
y = 2·x + 9
Where;
x = 7
y = 2 × 7 + 9 = 14 + 9 = 23
y = 23.

The roof of a building is 9 m high. A rope is tied from the roof to a peg on the ground 12 m away from the wall. What is the length of the rope?
Answer:
15 m
Step-by-step explanation:
Height of buiding h= 9m
Lenght from building l= 12m
let the length of the rope be x=???
Applying Pythagoras theorem
x^2=h^2+l^2
x^2= 9^2+12^2
x^2= 81+144
x^2=225
square both sides
x=√225
x=15 m
Hence the length of the rope is 15 m

If p(x) = 2x - 5 and r(x) = 3x + 4, calculate (pr)(x).
A 6x2 - 7x - 20
B 6x² +7X-20
C 5x - 1
D 6x2 - 20
Answer:
A) 6 x² - 7x - 20
Step-by-step explanation:
Explanation:-
Given p(x) = 2 x-5 and r (x) = 3 x +4
(pr)(x) = p(x) r(x)
= (2x -5)( 3 x +4)
= 2x(3x +4) -5( 3x +4)
= 6 x² + 8x - 15 x - 20
= 6 x² - 7x - 20
(pr)(x) = 6 x² - 7x - 20

Someone please help?? This is constant of proportionality... I don't get it at all and I need to turn this is ASAP!!!
Answer:
Step-by-step explanation:
From the given graph the line is straight ,so it means that the relation between x and y is directly proportional
(or) you can also say that at each point the slope of the line is same
slope =y/x , slope= 26/2 = 65/2 = 117/9 =13
hence slope is same that's why relation between x and y is direct relation
y∝ x
y=k*x
k=y/x
putt any point one the line to find the value of constant of proportionality,
i putt (2,26)
k=26/2 =13 value of proportionality constantnow to find cost of 14 tickets ,we have y=13*x , now putt x=14we will get cost(its on y-axis while ticket is on x-axis)y=13*14y= $182 cost of 14 ticketsso "C" option is correctAnswer:

On a unit circle, the terminal point of Ø is (1/2, square root 3/2), what is the cos Ø?
A. 1/2
B. Square root 3/3
C. Square root 3/2
D. Square root 3
The cosine of Ø is: [tex]\frac{1}{2}[/tex]
The ordered pair of a unit circle is represented as:
[tex](x,y) \to (\cos(\theta),\sin(\theta))[/tex]
The given parameters can be represented as:
[tex](x,y) \to (\frac{1}{2},\frac{\sqrt 3}{2})[/tex]
Recall that:
[tex](x,y) \to (\cos(\theta),\sin(\theta))[/tex]
Compare the above representation to:
[tex](x,y) \to (\frac{1}{2},\frac{\sqrt 3}{2})[/tex]
This means:
[tex]\cos(\theta) = \frac{1}{2}[/tex] and [tex]\sin(\theta) = \frac{\sqrt 3}{2}[/tex]

x + 4y = 7
4x – 3y = 9
Answer
{3,1}
Explaination
3 +4=7[1] x = -4y + 7
// Plug this in for variable x in equation [2]
[2] 4•(-4y+7) - 3y = 9
[2] - 19y = -19
// Solve equation [2] for the variable y
[2] 19y = 19
[2] y = 1
// By now we know this much :
x = -4y+7
y = 1
// Use the y value to solve for x
x = -4(1)+7 = 3
Solution :
{x,y} = {3,1}

Which three expressions in the table below have a solution of 10 when
x = -1 and y = 2
Answer:
The expressions are;
-5(x)(y)
8-y/x
Step-by-step explanation:
Here, we want to select expressions on the table having a solution of 10, given the value of x and y
For ;
-x(10) = -1(10) = -10
x + y + 7
-1 +2 + 7 = 8
8 -y/x = 8-(2/-1) = 8 + 2 = 10
-5(x)(y)
= -5(-1)(2) = 10
16-x + y - 7
16-(-1) + 2 - 7
16 + 1 + 2 - 7 = 12
