Answer:
(-4, -4)
Step-by-step explanation:
You have to put this in vertex form by completing the square in order to determine the vertex. Begin by setting the quadratic equal to 0 then moving the 12 over by subtraction:
The rules are to take half the linear term, square it, and add it to both sides. Our linear term is 8. Half of 8 is 4, and 4 squared is 16. So we add 16 to both sides:
During this process we have created a perfect square biomial on the left. We will state that, along with simplifying on the right:
Now we will move the 4 back over and set it back to equal y:
And from this you can see that the coordinates of the vertex are (-4, -4)
Hello,
I haven't found the ration of perfect squares methode unless it is to know all square root of numbers <100 (by heart)
As 41 is a primer number, I propose you an other old method (de Héron d'alexandrie)
Explanation:
x²=a
==>2x²=x²+a
==>2x=(x²+a)/x
==>2x=x+a/x
==>x=(x+a/x)/2 that is the recursive formula for the algorithm

Step-by-step explanation:
answer: if the x=2
16.2=32 32-6=26
4.2=8 8+1=9 26-9=17
5.2=10 10-2=8 17-8=9
7.2=14 14-5=9 9-9=0
Answer:
see below
Step-by-step explanation:
The transformation ...
g(x) = <em>a</em>·f(x -h) +k
represents ...
stretch if <em>a</em> > 1, compression if <em>a</em> < 1
if <em>a</em> < 0, there is a reflection across the x-axis
__
translation <em>right</em> by h units; <em>left</em> if -h is positive
translation <em>up</em> by k units; <em>down</em> if k is negative
_____
It's all about matching patterns.
