Answer:
Palanzio's Pizza: Y= .90x+6.80
Giudo's Pizza: Y= .65x+7.30
.90x + 6.80= .65x + 7.30
.25x + 6.80= 7.30
.25x = .50
x = 2

Answer:
<h2>
6cis120°</h2>
Step-by-step explanation:
The general form of a complex number z = x+iy
If x = rcos
and y = rsin
where r is the modulus of the complex number and is the argument, z in polar form is represented as:
z = rcos+ rsin
z = r(cos+ isin)
z = rcis
Given the complex number z=−3+3√3i
r = 
since the argument is negative and tan is negative in the 2nd and 4th quadrant,
In the second quadrant, theta = 180- 60 = 120°
On substituting r and theta, the complex number in polar form is expressed as 6cis120°
When solving an equation, you must do the same thing to both sides or else it won't be equal
when dealing with one unknown (x) try to get the unknown on one side
2(x-3)=1.2-x
distribute or multiply 2 by x then -3
so (2 times x)+(2 times -3[remember negative times positive=negative])
2x-6=1.2-x
add 6 to both sides
2x=7.2-x
add x to both sides
3x=7.2
divide both sides by 3
x=2.4
