If you would like to solve the system of equations x + y = 3 and 2x - y = 6, you can do this using the following steps:

<span>x + y = 3 ... y = 3 - x
2x - y = 6
</span>_________
<span>2x - y = 6
</span>2x - (3 - x) = 6
2x - 3 + x = 6
3x = 6 + 3
3x = 9     /3
x = 9/3
x = 3

<span>y = 3 - x = 3 - 3 = 0
</span>
The correct result would be x = 3.

Find the slope of each line then tell what the slope represents
morpeh [17]
1. find slope
x=tickets sold
y=money made
slope=(y2-y1)/(x2-x1)
take any point
(5,23.75) and (10,47.50)
input (note, (x,y))
(47.50-23.75)/(10-5)=23.75/5=4.75
slope=4.75
y=mx+b
m=slope
b=yintercept
y=4.75x+b
input
47.5=4.75(10)+b
47.5=47.5+b
b=0

equation is y=4.75x
if ticket sold is 24 then x=24
y=4.75(24)
y=114
answer is $114

2. points
(0,56.00) and (3,45.5)
slope=(y2-y1)/(x2-x1)
slope=(45.5-56.00)/(3-0)=-3.5
y=-3.5x
slope=-3.5
logic it yourself
equation is
y=-3.5x+0
y intercept is when x=0 so when the start of it was or when time=0
x intercept is when y=0 is when he has no money left





1.a. rate of change=4.75
   b. $114

2. a.do this yourself, (desmos graphing calculator)
   b. slope=-3.5 (duh, means money goes down with time)
   c. equaiton is y=-3.5x+0, xint meanss when he has no money, y int means when time=0 or when it started

What is the equation of a hyperbola with a = 9 and c = 12? Assume that the transverse axis is horizontal
Lorico [155]
The general equation of a hyperbola with a horizontal transverse axis is defined as:
x²/a² - y²/b² = 1

Solving for b², we use the formula: a² + b² = c²
b² = 12² - 9² = 63

Equation of our hyperbola will be:
x²/81 - y²/63 = 1

5z^3 - 2z^4 - 9z^2 + z
likoan [24]

Answer:

-z( 2z^3-5z^2+9z-1)

Step-by-step explanation:

Apply exponent rule: a^b+c=a^b*a^c

z^2=zz

z^3=z^2*z

z^4=z^3*z

Factor out common term z:

-z(2z^3-5z^2+9z-1)
