Determine the value of y, if x is 7. y=|x|+9 Answer:

Identify Given Values: Identify the given values and the expression to use. We are given that x is 7 and we need to find the value of y using the expression y = |x| + 9.Substitute Value of x: Substitute the value of x into the expression. Since x is 7, we substitute 7 for x in the expression to get y = |7| + 9.Evaluate Absolute Value: Evaluate the absolute value of x. The absolute value of 7 is 7, because 7 is already a positive number. So, |7| = 7.Perform Addition: Perform the addition to find the value of y. Now we add the absolute value of x to 9: y = 7 + 9.Calculate Final Value: Calculate the final value of y. Adding 7 and 9 gives us y = 16.

Answer:

Identify Given Values: Identify the given values and the expression to use. $\newline$ We are given that $x$ is $7$ and we need to find the value of $y$ using the expression $y = |x| + 9$ .
Substitute Value of $x$ : Substitute the value of $x$ into the expression. $\newline$ Since $x$ is $7$ , we substitute $7$ for $x$ in the expression to get $y = |7| + 9$ .
Evaluate Absolute Value: Evaluate the absolute value of $x$ . The absolute value of $7$ is $7$ , because $7$ is already a positive number. So, $|7| = 7$ .
Perform Addition: Perform the addition to find the value of $y$ . $\newline$ Now we add the absolute value of $x$ to $9$ : $y = 7 + 9$ .
Calculate Final Value: Calculate the final value of $y$ . Adding $7$ and $9$ gives us $y = 16$ .
