Find f(-5) if f(x) = |x + 1|.

5
4
6

B) 4

Step-by-step explanation:

Solve the Function Operation

f (−5)  f (x) = |x + 1|

Replace the variable x with −5 in the expression.

f (−5) = |(−5) + 1|

Simplify |(−5) + 1|.

Remove parentheses.

|(−5) + 1|

Add −5 and 1.

|−4|

The absolute value is the distance between a number and zero. The distance between −4 and 0 is 4

4

ab will be equal to

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
