Answer:
8
Step-by-step explanation:
just do 4x2=8
Answer:The correct answer among the choices given is option 2.
Completing the square is done as follows:
1. Write the equation in a way that the constants are in the right side while the terms with x are on the left.
5x^2 + 27x + 13x = 14
5x^2 + 40x = 14
2. Make sure that the coefficient of the x^2 term is 1.
5(x^2 + 8x) = 14
3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.
5(x^2 + 8x + 16) = 14 + 80
5(x+4)^2=94

Answer:
Opening: Opens upwards
Axis of Symmetry: -7/2
Vertex: (-7/2, -81/4)
X - intercepts: (1, 0) and (-8, 0)
Y - intercept: (0, -8)
Step-by-step explanation:
Opening: 'a' is greater than zero
Axis of Symmetry:
Vertex:
X - intercepts:
(x-1)(x+8)
x = 1 and x = -8
Y - intercept: (0, -8)
Answer:
equation of a line is given by
y -y1 / x - X1 ==> y2 - y1 / X2 - X1
where yi = 5, y2 = -2
and x1 = -2, x2 = 5
from the equation above
y -y1 / x - X1 ==> y2 - y1 / X2 - X1
y -5 / X -(-2) ==> -2-5 / 5 - (-2)
y -5 / X + 2 ===> -7 /7
y - 5/ X + 2 ===> -1
cross multiply
y -5 ==> -1(X + 2)
y -5 ==> -x -2
collect like terms
y + x -3 = 0
or
y + X ===> +3
Answer:
y=-2x
