Graphing is good to graph a line. Substitution is good because you have to subtitute the value whichis easy and elimination is good just to find oone variable first and the other variable

Graphing is a good method when you have small integers or fractions as your slope.
Substitution is a good method when you have two equations, and when one of the coefficient of the variables is one.
Linear combinations is a good method when you have the same coefficient for the same variable in 2 different equations.

A pine cone drops from a tree branch that is 36 feet above the ground. The function h = –16t2 + 36 is used. If the height h of t
scoray [572]
Notice that the height of the pine cone when it hits the ground is zero. So, to find the tame it takes for the pine cone to hit the ground, we just need to replace the height, h, with 0 in the function, and solve for time t:
h=-16t^2+36
0=-16t^2+36
-36=-16t^2
t^2= \frac{-36}{-16}
t^2= \frac{9}{4}
t=(+/-) \sqrt{ \frac{9}{4} }
t=(+/-) \frac{3}{2}
t=(+/-)1.5
Since time cannot be negative, the solution is t=1.5 seconds.

Since 1.5 second is significantly less than 2 seconds, we can conclude that <span>2 seconds is not a reasonable answer to this model.</span>
