(2x+1)(x-2) = 2x^2 - 4x +x -2= 2x^2-3x-2
Answer:
V( 3, -8 )
Step-by-step explanation:
Parable equation is of the form:
( x - h )² = 4p*(y - k)
In that expression, vertex has coordinates V ( h, k )
Then all we have to do is transform the given equation
y = x² - 6x + 1 or x² - 6x = y - 1 (1)
We can get a perfect square trinomial in the first member of the equation according to:
x² - 6x = ( x - 3 )² - 9
(x - 3 )² = x² - 6x + 9
By substitution en equation (1)
( x - 3 )² - 9 = y - 1
( x - 3 )² = y -1 + 9
( x - 3 )² = y + 8
( x - 3 )² = (y + 8 )
Then vertex coordinates are
V( 3 , -8)
We can use the difference of two squares, which is:
x^2 + y^2 = (x-y)(x+y)
So,
(9m-7)(9m+7)
Hope this helps!
Answer:
I think its choice C
Step-by-step explanation:
Because it makes more sense to me
5 * 1.5 to get 7.5, which is total pounds
7.5 - 2.8 to get how many almonds
= 4.7
Choice C makes the most sense to get that answer
i'm only in 5th grade so tell me if i'm wrong ill be ok with that
