What is the cost per pencil

$0.12/pencil

Step-by-step explanation:

The cost per pencil would be the unit cost or the slope of the given line.

Let's choose the point on the line (200, $24).  Note that the graph passes through (0, 0) as well.  Then the slope = unit cost per pencil is

m = rise / run = $24/200 pencils = $0.12/pencil

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
