Answer:

40 student 110 adult

this is using desmos

but to smash the equation you can go like basically we have to cancel out each variable to solve for the other

3x + 8y = 1000

x + y < =150

-3(x + y <= 150)

-3x -3y = -450

3x + 8y = 1000

5y = 550

y= 110

3x + 8 y = 1000

-8(x+y<=150) = -8x - 8y <= -1200

-5x = -200

$\frac{ - 5x}{ - 5 } = x$

$\frac{ - 200}{ - 5} = 40$

x= 40

What is the first step when rewriting y = 3x2 9x – 18 in the form y = a(x – h)2 k?

stiks02 [169]

A quadratic equation has the general form of: 

y=ax² + bx + c

It can be converted to the vertex form in order to determine the vertex of the parabola. It has the standard form of:

y = a(x+h)² - k

This can be done by completing a square. The steps are as follows:

y = 3x2 + 9x – 18
y = 3(x2 + 3x) – 18
y + 27/4= 3(x2 + 3x+ 9/4) – 18
y = 3(x2 + 3/2)^2 – 99/4

Therefore, the first step is to group terms with the variable x and factoring out the coefficient of x^2.
