So to solve problems like these you can work out each equation by substituting the x and y with the coords from the vertex (2,-4) and which ever one is true is the corresponding equation.
Lets try the first one
A) y = 2( x-2)^2-4 this would become
-4 = 2(2-2)^2-4 we solve this and get
-4 = 2(0)-4
-4 = -4
so it seems like A is the correct answer, of course we'd wanna check out the other answers just to be sure.
Lets try one and do C
C) -2 = 2(-4-2)^2+2
-2 = 2(-8)^2+2
-2 = 130
These aren't equal so this can't be our equation
So you can also do one more just to be super sure you have the right answer but I think A is the correct one :)
Hey there!
m(4 + 7)
= 1m(4 + 7)
DISTRIBUTE m WITHIN the PARENTHESES
= m(4) + m(7)
= 4(m) + 7(m)
= 4(1m) + 7(1m)
= 4m + 7m
COMBINE the LIKE TERMS
= 11m
Therefore, your answer is: 11m
Good luck on your assignment & enjoy your day!
