Answer:

x = price of balcony tickets = $7

y = price of orchestra tickets = $21

Step-by-step explanation:

Let

x = price of balcony tickets

y = price of orchestra tickets

y = 3x (1)

148y + 76x = 3,640 (2)

Substitute y = 3x into (2)

148y + 76x = 3,640 (2)

148(3x) + 76x = 3,640

444x + 76x = 3,640

520x = 3,640

x = 3,640/520

x = 7

Substitute x = 7 into (1)

y = 3x (1)

y = 3(7)

y = 21

x = price of balcony tickets = $7

y = price of orchestra tickets = $21

Answer:

• The function is a linear function

• The function changes at a constant rate

Step-by-step explanation:

A graph of the function shows it to be a straight line (linear function). Such a function always changes at a constant rate. The line goes downward to the right, so the function is a decreasing function.

___

"changes at a constant rate" and "linear function" are two different ways of saying the same thing: the graph of the function is a straight line.

Find the x-intercepts of the parabola with vertex (1,-108) and y-intercept (0,-105). Write your answer in this form: (X1,y1), (x

Stolb23 [73]

Answer:

(7, 0) and (-5, 0)

Step-by-step explanation:

<u>Vertex form</u>

$y=a(x-h)^2+k$

(where (h, k) is the vertex)

Given:

vertex = (1, -108)

$\implies y=a(x-1)^2-108$

Given:

y-intercept = (0, -105)

$\implies a(0-1)^2-108=-105$

$\implies a(-1)^2=-105+108$

$\implies a=3$

Therefore:

$\implies y=3(x-1)^2-108$

The x-intercepts are when y = 0

$\implies 3(x-1)^2-108=0$

$\implies 3(x-1)^2=108$

$\implies (x-1)^2=36$

$\implies x-1=\pm \sqrt{36}$

$\implies x=1\pm 6$

$\implies x=7, x=-5$

Therefore, the x-intercepts are (7, 0) and (-5, 0)

Determine the value of x.

telo118 [61]

Answer:

Step-by-step explanation:

This triangle is isosceles, same as the little triangle.

If one side of the little triangle is 3x, then the little side with the tick (let's name it a) is also 3x.

That means the longer side, 2a, is 6x

This triangle is isosceles, so 6x = 4x + 20

Now, if we solve that, x = 10

The answer is 10

Hope this helps :)

Have a good day!

How many non-square numbers lie between the 215to the power of 2 and 216 to the power of 2

Vaselesa [24]

There are 430 non square numbers that lie between $215^{2}$ and $216^{2}$ .

Given two numbers $215^{2}$ and $216^{2}$ and we are require to find non square numbers that lie between them.

Numbers can be consecutive numbers or non consecutive numbers. In our question we will find the consecutive numbers.

Square numbers are those numbers whos square is in a proper number means decimal should not be there.

First number= $215^{2}$

Second number= $216^{2}$

First we have to find the exact value of numbers by finding the square of these numbers.

First number=215*215=46225

Second number=216*216=46656

Numbers that lie between them=(46656-46225)-1

=431-1

=430

Hence 430 numbers lie between $215^{2}$ and $216^{2}$ .
