Answer:

f(0) = 14

Step-by-step explanation:

Given

f(x) = \left \{ {{|x - 8| + 6 \ x

Required

Find f(0)

From the piecewise function, we have the following as values of f(x):

f(x) = |x - 8| + 6

If x < 4

f(x) = 15

If x \ge 4\\

f(0) implies that x =0 and 0

So, we make use of the first function, which is:

f(x) = |x - 8| + 6

Substitute 0 for x in f(x) = |x - 8| + 6

f(0) = |0 - 8| + 6

f(0) = |- 8| + 6

|-8| = 8

So, the expression becomes

f(0) = 8 + 6

f(0) = 14

<em></em>

<em>Hence, the value of f(0) is 14</em>

adelina 88 [10]

Answer:

Step-by-step explanation:

The two inside angles will sum to 180°.

The top to angles are equal.  

Think about this as what if both of the parallel lines were intersected by a perpendicuar line.  Every angle would be a right triangle 90°.  The inside angles will sum to 180° and the opposite angles are again equal.

 (2x + 18) + (8x + 12) = 180

          10x +   30   =   180

                   10x    =   150

                      x  =  15

-------------------------

             (3y - 18)  =  (8x + 12)       x = 15

            (3y - 18)  =  (8(15) + 12)

            (3y - 18)  =  (120 + 12)

            (3y - 18)  =  132

                   3y   =   132 + 18

                   3y   =  150

                     y   =  50
