Answer:
The correct option: <u>x + y = 6 </u>
Step-by-step explanation:
In a Cartesian system or a coordinate system, the abscissa is the value of the horizontal (x) value and the ordinate is the value of the vertical (y) value.
So, The sum of the abscissa and the ordinate = x + y when written as an algebraic expression.
Since given that The sum of the abscissa and the ordinate is six
So, the correct equation is x + y = 6
Correct answer is B... You can plug in values for n. Plug in 1 for n and the out put is 12. Plug in 2 for n and the output is 13.5
Answer:
Option 3.
Step-by-step explanation:
The given function is
where, h(t) is the height of a small rock falling from the top of a 124-ft-tall building and t is the time in seconds.
It is a downward parabola.
Equate the function equal to 0, to find the time at which the rock touch the ground.
If 
, the according to the quadratic formula
Using quadratic formula, we get
Time cannot be negative. So, the rock remain in the air in the interval 0 < t < 2.
Therefore, the correct option is 3.
Answer:
C
Step-by-step explanation:
x^3+4x^2-9x-36=0
or x²(x+4)-9(x+4)=0
or (x+4)(x²-9)=0
or (x+4)(x+3)(x-3)=0
x=-4,-3 or 3
