Answer:
f(5) = 5
Step-by-step explanation:
F(x)=x^2 - 4x
Let x = 5
F(5)=5^2 - 4*5
= 25 - 20
= 5
Answer:
D = -4
E = 2
Step-by-step explanation:
The procedure for completing the square method is given as:
x2 + bx + c = 0
x2 + bx = -c
x2 + bx + (b/2)2 = -c + (b/2)2
Aolving the LHS simultaneously,
(x + b)2 = -c + (b/2)2
Find the square root of both sides,
(x + b) = sqrt(-c + (b/2)2)
So for the equation, x2 - 8x + 12
x2 - 8x = -12
x2 - 8x + 16 = -12 + 16
(x - 4)2 = 4
So square root both sides,
(x - 4) = 2
Comparing this to the equation given,
(x - D) = E;
D = -4
E = 2
Answer:
y = - x + 2
Step-by-step explanation:
the slope is negative, so eliminate choice 2 and 3.
the y intercept is 2 and the slope is -1, hence the answer is choice 4
