The price of an adult ticket is 12$.
And the price of a student ticket is 9$.
Let ‘x’ be the price of an adult ticket.
Let ‘y’ be the price of a student ticket.
On the first day of ticket sales, the school sold 14 adult tickets and 3 student tickets for a total of $195 i.e
14x + 3y = 195$ i)
15x + 14y = 306$ ii)
from equation i) we get the value of y,
y = (195 - 14x)/3
put this value of y in equation ii) we get,
= 15x +14{(195 - 14x)/3} = 306
= (45x +2730 - 196x)/3 = 306
= (45x +2730 - 196x) = 918
= -151x = -1812
= x =12$
then value of y we get ,
put value of x in y,
y = (195 - 14*12)/3
= 27/3
= 9$
hence, the price of an adult ticket is 12$.
And the price of a student ticket is 9$.

2. On Friday, the Lee family had dinner at a
restaurant. They ordered 12 cheeseburgers and
4 chili bowls for $19.40. The following Friday,
the Lee family went back to the same restaurant.
They ordered 8 cheeseburgers and 6 chili bowls
for $16.60. How much does a cheeseburger
cost?
Answer:
cheeseburger costs $1.25
Step-by-step explanation:
let x be the cost of a cheeseburger and y the cost of chilli and set up 2 simultaneous equations, that is
12x + 4y = 19.4 → (1)
8x + 6y = 16.6 → (2)
multiplying (1) by 6 and (2) by - 4 and adding the result will eliminate y
72x + 24y = 116.4 → (3)
- 32x - 24y = - 66.4 → (4)
add (3) and (4) term by term to eliminate y
40x + 0 = 50
40x = 50 ( divide both sides by 40 )
x = 1.25
the cost of a cheeseburger is $1.25
We used these functions to represent the two sides of the equation:
f(x) = 3x
g(x) = 4x + 1
Graph the functions y = f(x) and y = g(x) on the same coordinate plane.
The solution to the system of equation graphed is (-1, -3)
Solution to system of equationGiven the system of equations graphed on the plane expressed as:
f(x) = 3x
g(x) = 4x + 1
Equate
f(x) = g(x)
3x = 4x + 1
3x - 4x = 1
-x = 1
x = -1
Determine the value of y
y = 3x
y = 3(-1)
y = -3
Hence the solution to the system of equation graphed is (-1, -3)

Find the value for y. Geometry!! pls help!! thank youuuu
Answer:
2
Step-by-step explanation:
By the triangle proportionality theorem,
[tex] \frac{12}{2y - 1} = \frac{4y - 4}{1} \\ \\ 12 = (2y - 1)(4y - 4) \\ \\ 12 = 8 {y}^{2} - 12y + 4 \\ \\ 8 {y}^{2} - 12y - 8 =0 \\ \\2 {y}^{2} - 3 y - 2 = 0 \\ \\ (2y + 1)(y - 2) = 0[/tex]
From this, we know that y = -1/2 or 2.
However, as distance must be positive, we disregard the negative case, giving us y = 2.

Answer:
y=2/3(x-3)^2+1
Step-by-step explanation:
The parent function of a parabola is y=x^2:
The transformation of this graph shows the parabola is shifted to the right 3 and up 1 so we apply that to our equation y=(x-3)^2+1
to solve the stretch factor:
y=a(x-3)^2+1
we can see when x=0 y=7 so we use this set
7=a(0-3)^2+1
7=a(-3)^2+1

2. A person takes a loan of Rs 100 000 at an interest rate of 4.2% compounded annually and deposits it in a bank that pays 8% interest compounded annually. What is the profit of his investment after 2 years?
The profit of his investment after 2 years is $8,063.60.
What is the profit of his investment?The profit earned is the difference between the amount he earned from the deposit at the bank and the interest paid on the loan.
Total value of the loan in 2 years : 100,000 x (1.042²) = 108,576.40
Total value of the amount deposited in 2 years : 100,000 x (1.08²) = 116,640

At the end of week 3, plant 1 is 0.6 inches taller than plant 2.
How much taller is plant 1 than plant 2 at the end of week 3?For plant 1, the height (in inches) equation as a function of the number of weeks is:
[tex]h_1(w) = 2.5 + \frac{4}{10}*w[/tex]
The height for w = 3 is:
[tex]h_1(3) = 2.5 + \frac{4}{10}*3 = 3.7[/tex]
So the height at the end of week 3 is 3.7 inches.
For plant 2 the equation is:
[tex]h_2(w) = 2.5 + \frac{1}{5}*w[/tex]
The height for w = 3.
[tex]h_2(3) = 2.5 + \frac{1}{5}*3 = 3.1[/tex]
So the height at the end of week 3 is 3.1 inches.
The difference is:
3.7 in - 3.1 in = 0.6 in
At the end of week 3, plant 1 is 0.6 inches taller than plant 2.
