The flight path of a toy rocket launched from the top of a 240ft tall building is represented by the equation : - 16t2 + 128t + 240 = 0

For how many
seconds is the toy rocket in the air? Hint: Use the quadratic formula to find
the solution.

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:

answer: what in the world is this

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
