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

Lisa walked 8 miles more than Tim . Lisa walked twice as far as Tim . How far did each walk ?

adoni [48]

L = 8 + T
L = 2T

You can combine them

2T = 8 + T
T = 8

If Tim walked 8, Lisa walked twice as much which is 16

Answer:

B. $p^2+p-11$ .

Step-by-step explanation:

Step 1:

$((((3+(4*(p^2)))-5p)-3p^2)+4p)+8$

Step 2:

$((((3 + 22p^2) - 5p) - 3p^2) + 4p) + 8$

Step 3:

Factoring $p^2-p+11$
The first term is, $p^2$ its coefficient is 1 .
The middle term is, -p its coefficient is -1 .
The last term, "the constant", is +11
Step-1 : Multiply the coefficient of the first term by the constant 1 • 11 = 11
Step-2 : Find two factors of 11 whose sum equals the coefficient of the middle term, which is -1 .
-11 + -1 = -12
-1 + -11 = -12
1 + 11 = 12
11 + 1 = 12
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
