Chapter 3: Q1. (page 146)

Which property will use the inequality $- 7 y \leq 49$ ?

Short Answer

Expert verified

The division property of inequality is used to solve the equation.

Step by step solution

Step -1 - Apply the concept of Linear inequalities

In this type of inequality, Simply use the property of addition or subtraction of suitable number on both Left Hand Side & Right Hand Side to maintain the inequality and also the variable & numbers should be at the different sides in the equation.

Step -2 – Find the value of y by solving the inequality

Since, the equality is $- 7 y \leq 49$ .

Here, to simplify this inequality, use the division property to solve it, divide by $- 7$ to both side of the equation,

$\begin{array}{l} - 7 y \leq 49 \\ \frac{- 7 y}{- 7} \leq \frac{49}{- 7} \\ y \leq - 7 \end{array}$
