Answer:

a constant is a data item whose value cannot change during the program execution just as its name implies that the value is constant a variable is a data item whose value can change during the program's execution . Thus as its name implies the the value can vary

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

$f(0) = 8 + 6$

$f(0) = 14$

Hence, the value of f(0) is 14

Given m n, find the value of x and y. (37-18) (8x+12) m (2X+18) n

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
