Answer:
Quadrant 1, I think.
Step-by-step explanation:
When you factor this quadratic (or any polynomial, for that matter), what you get are the zeros of the function. When the object is on the ground, its height is 0. The zeros of a function are where the graph goes through the x-axis. Where the graph goes through the x-axis, the y value is 0. Using the quadratic formula to factor this gives you zeros of t = -1 and t = 7. The two things in math that will never EVER be negative are time and distance/length, so we know that object will hit the ground 7 seconds after it is thrown.
Answer:
n=3
Step-by-step explanation:
-5 (6n +8) =50
First distribute the -5 to 6n and 8. Remember to multiply with the sign!
so -5 x 6n and -5 x 8
which = -30n and -40
so our new equation is
-30n - 40=50
we add 40 to the other side since we want the answer of the variable
-30n - 40 +40 = 50+40
-30n =90
we divide -30 from n to get n alone.
-30n/-30 = 90/-30
n=-3
We can check our answer by plugging it into the equation.
50= -5 (6(-3) +8)
50 = -5 (-18+8) -> 50= -5 (-10)=50
