0.925x^2 - 4x + 20 = -1.125x^2 + 6x + 40 (at break even point)
2.05x^2 - 10x - 20 = 0
x = [ - (-10) +/- sqrt(100 - 4*2.05*-20) / (2*2.05)
x = 6.40, -1.52 Ignore the negative
Answer is 6.40
Answer:
2/3x+5=y
Step-by-step explanation:
We already know that this has to be linear and that its y-intercept is 5 ((0,5) is a point on the table). That means that the equation is
mx+5=y.
Now all we need to do is plug in some points.
3m+5=7
(Subtract 5 from both sides)
3m=2
m=2/3
x ≤ 3
Step-by-step explanation:
4x ≤ 12
divide each side by 4
x ≤ 3
Answer:
3x(3x-5)
Step-by-step explanation:
I can do this in my head but I hope it is right but if not I'm sorry
4.
A non function is when xs repeat… the x is repeat which is 5
