Answer:2
Step-by-step explanation: 9+1+2=12
12\3=4
ANSWER : 2
Answer: x ( y + 1) + y ( y + 3) + 2
Step-by-step explanation:
( x + y + 2) ( y + 1)
x ( y + 1) + y ( y + 1) + 2 ( y + 1)
expanding the bracket
( xy + x) + ( y2 + y) + ( 2y + 2)
removing the bracket
xy + x + y2 +y + 2y + 2
collecting like terms
xy + x + y2 + 3y + 2
given as: x(y + 1) + y ( y + 3) + 2
Answer:
y=-5x-5
Step-by-step explanation:
The line contains points at (-2,5) and (0,-5)
(y1-y2) / (x1-x2) = slope
(-2,5) =(x1,y1)
(0,-5) = (x2,y2)
(5--5) / (-2-0)
10 / -2 = -5
y= -5x + b
plug in points for x and y to find b
5=-5(-2)+b
5=10+b
-5=b
y=-5x-5
Answer:
D
Step-by-step explanation:
Given that
f(x)=-2x – 1
g(x) = -1/2x+1/2
I The function f( g(x)) = x for all real x.
-2(-1/2X + 1/2) - 1
X - 1 - 1
X - 2
II. The function glAx)) = x for all real x.
- 1/2( -2X - 1 ) + 1/2
X + 1/2 + 1/2
X + 1
III. Functions fand g are inverse functions
Inverse of f(x)
Y = -2x - 1
X = - 2Y - 1
- 2Y = X + 1
Y = - 1/2X - 1/2
Therefore, none of the above answers is correct.
The correct answer is therefore D
