Explain how you know a system of equations has

1 answer:

4 0

When they have no solutions, the lines are parlaell, or they have the same slope but different y intercept
example

3x+2y=2 and
3x+2y=4 are paralell
also
y=3x+2 and
y=3x+4 are also parlell, no solutions

infinite solutions are when they are the same line
they have the same slope and y intercept
to find out, simplify
3x+2y=4 and
6x+4y=8 are smae lien
also
y=3x+2 and
2y=6x+4 aer the same line

1 solution is when it is none of the above things
a normal thing, where the slopes are differnet
example
y=2x+2
y=3x+2

Graph the equation h=-16t^2+80. click on the graph until the correct solution appears

Andru [333]

The graph of $f(x)=-16 t^{2}+80$ is shown in the graph below.

The graph is of ∩-shape when the constant $a$ of the quadratic equation $a x^{2} +bx+c$ is negative
