The solution to an inequality is graphed on the number line.

Charra [1.4K]

Because the arrow is pointing to the left, the answer to the solution set needs to be less than the the number the dot is on.

A solid dot on a number means that that number is included in the solution set.

In the picture the solid dot is on 4.5, so the solution set needs to be equal to or less than 4.5.

The answer is:

{x | x ≤ 4.5}

Simply the product -7x/5y * 5x/-7

ch4aika [34]

We are asked to simplify the expression $\frac{-7x}{5y} \cdot \frac{5x}{-7}$ ,

what we do is, we form a single fraction where the numerator is the product of the numerators, and the denominator is the product of the denominators, that is:

$\frac{-7x}{5y} \cdot \frac{5x}{-7}= \frac{-7\cdot5 \cdot x \cdot x}{5 \cdot(-7) \cdot y}$

simplify the common numbers and terms in the numerator and denominator:

$\frac{-7\cdot5 \cdot x \cdot x}{5 \cdot(-7) \cdot y}=\frac{5 \cdot x \cdot x}{5 \cdot y}=\frac{x \cdot x}{y}= \frac{ x^{2} }{y}$

Answer: $\frac{ x^{2} }{y}$

Is -9.7 rational or irrational give reasoning

asambeis [7]

A rational number is any number that can be expressed as a ratio of two integers (hence the name "rational"). For example, 1.5 is rational since it can be written as 3/2, 6/4, 9/6 or another fraction or two integers. Pi (π) is irrational since it cannot be written as a fraction.
