Identify the variation as direct, inverse, joint or combined. if the area of a rectangle stays constant, the relationship between the base and the height. direct inverse joint combined

Inverse variation

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form

Let

x-----> the length of the rectangle

y-----> the width of the rectangle

The area of the rectangle is equal to

If the area of a rectangle stays constant

then

so

------> represent an inverse variation

If the length increase------> the width decrease

If the length decrease------> the width increase

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
