Example 1:For the function f(x) = x + 4, what is the ordered pair for the point on the graph when x = 3p?

Example 2:
If g(x) = 3(x − 2), find the value of x if g(x) = 6

The question is what is F(1) , what dose it equal?

Answer 1
Answer: Simply substitute x by its value:

1) 
f(x) = x + 4 ; x = 3p                    f(x) = x + 4 ; 
f(3p) = 3p + 4                            f(1) = 1 + 4
                                                 f(1) = 5
x = 3p                                        (1,5)
y = 3p + 4

2) g(x) = 3(x-2)                           g(x) = 3(x-2)
    g(x) = 6                                  g(1) = 3(1-2)
                                                  g(1) = 3 - 6
6 = 3x - 6                                   g(1) = -3
6+6 = 3x                                       (1,-3)
12 = 3x
x = 4
g(4) = 3(4-2)
g(4) = 12 - 6
g(4) = 6

x = 4
y = 6

Graph the equation x-y=6

Answers

x-y=6\n\nThe\ slope-intercept\ form:y=mx+b\n\n-y=-x+6\ny=x-6\n\ny-intercept\ (x=0)\ny=0-6=-6\n(0;-6)\n\nx-intercept\ (y=0)\n-x+6=0\nx=6\n(6;\ 0)
x-y-6=0 is the standard form you can graph this by using the y-x intercept form 
x-intercept y=0 
x-6=0 
x=6 
y-intercept, x=0 
-y-6=0 
-y=6
y=-6 
therefore you can plot points on (0,-6) and (6,0) ad connect them together 

A piece of licorice is to be cut into 10 equal size pieces . If the length of the piece of licorice is 2/3 yard, how long will each piece of licorice be?

Answers

The first thing to do is turn this into an equation: 
2/3 ÷ 10 

10 as a fraction is 10/1
2/3 ÷ 10/1 = 

Fractional division is just fractional multiplication after switching the numerator and the denominator of the second fraction: 
2/3 X 10/1 

Fractional multiplication is simply multiplying the numerators by each other, and the denominators by each other: 
2 X 10 = 20
3 X 1 = 3

20/3

Each piece of liquorice will be 20/3 or 6 2/3 of a yard long. 

Answer: 20/3
