Answer:
Option D.
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to
where
(h,k) is the vertex of the parabola
If a> 0 then the parabola open up and the vertex is a minimum
If a< 0 then the parabola open down and the vertex is a maximum
In this problem the vertex is the point (-2,5)
so
the equation must be equal to
and the value of a is positive
therefore
the answer is the option D
Answer:
(- 3, - 6)
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
y = 2(x + 3)² - 6 ← is in vertex form
with (h, k) = (- 3, - 6 ) ← vertex
Answer:
(1, - 2 )
Step-by-step explanation:
Given the 2 equations
y = - 4x + 2 → (1)
y = x - 3 → (2)
Since both equations express y in terms of x, equate the right sides
x - 3 = - 4x + 2 ( add 4x to both sides )
5x - 3 = 2 ( add 3 to both sides )
5x = 5 ( divide both sides by 5 )
x = 1
Substitute x = 1 in (2) for corresponding value of y
y = 1 - 3 = - 2
Solution is (1, - 2 )
Answer:
7 4/6 - 5 5/6 = 1.83 or 1 5/6

Start with the factors of ten. (1x10) (2x5) (-1x-10) (-2x-5)
Which of these pairs also adds to give you -11?
-1 + - 10 = -11
So the numbers are -1 and -10
