The equation shows direct variation
true or false ?

false.

Step-by-step explanation:

A direct variation equation is an equation where one fo the variable is equal to a constant times the other variable, we can write a general direct variation equation as:

y = k*x

Notice that the y-intercept is equal to zero in this type of equations.

Where y and x are the variables, and k is the constant.

In this case, we have the equation:

y = x - 7

Notice that in this equation we have a y-intercept equal to -7, which is different than zero.

Then the equation does not show direct variation, which means that the statement is false.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
