Determine the value of y, if x is -7 . y=(21)/(x+10) Answer:

Substitute x value: Substitute the value of x into the equation. Given the equation y = (21)/(x+10), we need to substitute x with -7. y = (21)/(-7+10)Simplify expression: Simplify the expression inside the parentheses. Calculate the value inside the parentheses (-7+10). y = (21)/(3)Divide to find y: Divide 21 by 3 to find the value of y. Perform the division to solve for y. y = 7

Q. Determine the value of

y

, if

x

-7

\newline

y=\frac{21}{x+10}

\newline

Answer:

Substitute $x$ value: Substitute the value of $x$ into the equation. $\newline$ Given the equation $y = \frac{21}{x+10}$ , we need to substitute $x$ with $-7$ . $\newline$ $y = \frac{21}{-7+10}$
Simplify expression: Simplify the expression inside the parentheses. $\newline$ Calculate the value inside the parentheses $(-7+10)$ . $\newline$ $y = \frac{21}{3}$
Divide to find $y$ : Divide $21$ by $3$ to find the value of $y$ . Perform the division to solve for $y$ . $y = 7$
