First, we have to realize that this is factored form, so we have to put this in standard quadratic form using FOIL, which is a rule mandating how we multiply the numbers here. F stands for First, which means the first number inside the parentheses for both of them, then O means the first number in the first quantity(fancy word for parentheses) multiplied by the last number of the second quantity, and so forth. When you are done, you combine like terms
anyway, you end up with x²-12x-189, but you have to inverse all numbers because of the parentheses in front, so it becomes -x²+12x+189.
Now you can find the axis of symmetry uisng the equation -b=2a (oh yeah, I forgot to mention: the standard quadratic form is a(x)²+b(x)+c already). So you do -12 / -2, which then becomes 6.
The axis of symmetry is 6
Inverse Variation is shown through the formula y=k/x
plug in the given values and solve for k: 3=k/5 so k=15
Answer: y=15/x
Answer:
All of them
Step-by-step explanation:
if you divide 24 by 8 the you would get 3 and if you divide 24 by 4 them you will get 6 and if you divide 24 by 3 you will get 8
Answer:
The decimal 2.8 is equivalent to 26/9
Hope this helps
