Please help me answer. I do not understand inequalities.

90

5 + .50x = 50

Step-by-step explanation:

We have a flat fee of 5 dollars, so that is the constant in the equation. It costs 50 cents per ticket.

So

5 + .50x = 50

50 - 5 = 45

.50x = 45

45/.50 = 90

You can buy 90 tickets if you have 50 dollars to spend.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
