The vertex is the point at which the parabola or quadratic equation opens up or down. To calculate the parabola, we must use the formula: -b/2a = x; x = -16/2(4) x = -2
Substitute -2 in where you see x appear and do the arithmetic to find that y = -15. Therefore, the vertex coordinates are (-2,-15).
Answer:
Step-by-step explanation:
So 1cm rep = 24 ÷ 2 = 12
So 3cm rep = 12 x 3 = 36
There is no picture added. I can not help with that then.
You simply substitute the coordinates into the given equation
so
-7 = 3k + 2
then solve from there
-9 = 3k
-3 = k
A=10, B=11, C=12, etc.
Now, the "only" thing that remains to do is solving the above equation.
While making this problem I only made sure it has a solution. I didn't try to solve it myself and I didn't know it will end up with such "convoluted" polynomial. Sorry to everyone who tried to solve it... m(_ _)m
I think the best way to approach it is using the rational root theorem since we know that . Moreover we can deduce that since there is and .
After you succesfully solve it, you should get the answer .
