The answer would be -8+-88a
Answer:
x=2
Step-by-step explanation:
(x+2)(x-6)= y
0 = x+2 0 = x-6
The zeros of the functions are at -2 and 6 using the zero product property
We know a parabola is symmetric so the vertex is 1/2 way between the zeros
(-2+6)/2 = 4/2 =2
The x coordinate of the vertex is at 2
Answer:
Step-by-step explanation:
How can you remember the formula?
Well, it helps to know it's the Pythagoras Theorem with something extra so it works for all triangles:
Pythagoras Theorem:
(only for Right-Angled Triangles) a2 + b2 = c2
Law of Cosines:
(for all triangles) a2 + b2 − 2ab cos(C) = c2
So, to remember it:
think "abc": a2 + b2 = c2,
then a 2nd "abc": 2ab cos(C),
and put them together: a2 + b2 − 2ab cos(C) = c2
Answer:
(y+2) / y
Step-by-step explanation:
Just do what is says f(x ) = (y+2) / y
Okay, so the place values are ones, tens, and then then hundreds, from the right to left. Following that pattern, the 0 would be the ones, the 2 would be tens, and the 3 would be the hundreds. So, now you know how to find the place value, you can determine that there are 3 hundreds, 2 tens, and ones, or 20 ones and 3 hundreds.
