Question 1)
g [ f(x) ] = ? ;
→ Given: " f(x) = 1/3 x " ;
→ Given: " g(x) = 3x " ;
__________________________________
g [ f(x) ] = g(1/3 x) = 3(1/3 x) = 1x = "x" .

Question 2)
g [ f(1/2) ] = ? ;
__________________________________
→ Given: " f(x) = 1/3 x " ;
→ f(1/2) = (1/3) * (1/2) = (1*1) / (3*2) = (1/6) ;
→ g [ f(x) ] =
g(1/6) = 3* (1/6) = (3/1) * (1/6) = (3*1) / (1*6) = 3/6 = (3÷3) / (6÷3) = " 1/2 " .

Answer:
Step-by-step explanation:
1). Let the equation of a line is,
y = mx + b
Here, m = slope of the line
b = y-intercept
From the graph attached,
Slope = =
y-intercept = -2
Equation → y =
2). Slope of the line =
y-intercept 'b' = -3
Equation → y =
3). Slope of the line =
=
y-intercept = 5
Equation → y =
4). Slope of the line =
y-intercept = 4
Equation → y =
5). Since, line is passing through origin (0, 0)
y-intercept = 0
Slope =
Equation → y = x
6). Slope of the line =
y-intercept = -4
Equation → y =
Answer:
Step-by-step explanation:
eq1. x + 2y = 11
eq2. 6x + 4y = 34
------------------
Objective is to eliminate one of the variables, either x or y.
Let's eliminate y by multiplying the top equation with the number 2.
2x +4x = 22
Now multiply the bottom equation by -1
2x +4x = 22
-6x -4x = -34
------------------
Now add both equation and you will see that y will be eliminated.
So therefore, the answer is A.2
