Question

Given b(x) = |x+4| , what is b(-10)

Answer 1

Answer:

6

Step-by-step explanation:

|-10+4| = |-6|= 6

inside the | | the equation is done normally. that's why it has a negative at first. then, once getting rid of the bars, you change the number to a positive

Answer 2

Answer:

$\boxed {\tt b(-10)=6}$

Step-by-step explanation:

We are given the function:

$b(x)= \mid x+4 \mid$

We want to find b(-10). Therefore, we must plug -10 in for each x.

$b(-10)= \mid -10+4 \mid$

Solve inside of the absolute value symbol. Add 4 to -10 ⇒ -10+4= -6

$b(-10)= \mid -6 \mid$

Absolute value represents how far away a number is from 0. It is always positive.

-6 is 6 away from 0. Therefore, the absolute value of -6 is 6.

$b(-10)= 6$

b(-10) is equal to 6.
