This answer is A.
Basically, the parabola opens downward so you know that the equation has a negative in the front...
His reasoning is not valid because they might actually appear to be equal to his sight, but should he measure them they might not exactly be.
So he just can't look at it and conclude. He can say it is equilateral if each angles measures 60 degrees.
A circle with a radius of 15.4 meters
Can the 2/5 invite a fraction and add them
Step-by-step explanation:
First of all, use substitution to find slope
(1) = m(3) - 2
3 = m3
m = 1
With both the slope and y int, you can write it in y int form
y = 1x - 2
Convert that to standard form
-x + y = -2
