Determine the value of y, if x is -2 . y=|x|+7 Answer:

Substitute -2 for x: We are given the expression y = |x| + 7 and the value x = -2. Substitute -2 for x in the expression. y = |-2| + 7Evaluate absolute value of -2: Evaluate the absolute value of -2. The absolute value of a number is its distance from zero on the number line, which is always non-negative. |-2| = 2Continue with the expression: Now that we have the absolute value of x, we can continue with the expression. y = 2 + 7Find the value of y: Add the numbers to find the value of y. y = 9

Q. Determine the value of

y

, if

x

-2

\newline

y=|x|+7

\newline

Answer:

Substitute $-2$ for $x$ : We are given the expression $y = |x| + 7$ and the value $x = -2$ . $\newline$ Substitute $-2$ for $x$ in the expression. $\newline$ $y = |-2| + 7$
Evaluate absolute value of $-2$ : Evaluate the absolute value of $-2$ . The absolute value of a number is its distance from zero on the number line, which is always non-negative. $|-2| = 2$
Continue with the expression: Now that we have the absolute value of $x$ , we can continue with the expression. $y = 2 + 7$
Find the value of $y$ : Add the numbers to find the value of $y$ . $y = 9$
