Answer:

The slopes of WX and XZ

Step-by-step explanation:

The singular factor that determines if the parallelogram is a rectangle are the angles at the edges

Mathematically, we can only have a rectangle if there are four right angles with one right angle each at the edges of the rectangle

So, by having the slope of the sides forming the width and that which forms the length, we can deduce if what we have is rectangle given that the slopes will yield a perpendicular product

Hence, the slopes of WX and XZ can be calculated to show this

Choose all equivalent expression(s).

ElenaW [278]

Given:

The given expression is $a b^{-3 x}$

We need to determine the equivalent expression.

Equivalent expression:

Let us determine the equivalent expression.

The equivalent expression can be determined by simplifying the given expression.

Hence, let us apply the exponent rule to simplify the given expression.

Thus, applying the exponent rule, $a^{-b}=\frac{1}{a^{b}}$ , we get;

$a(\frac{1}{b^{3x}})$

Rewriting the expression, we get;

$a(\frac{1^{3x}}{b^{3x}})$

Simplifying, we get;

$a\left(\frac{1}{b}\right)^{3 x}$

Thus, the equivalent expression is $a\left(\frac{1}{b}\right)^{3 x}$

Hence, Option C is the correct answer.

Solve the equation for x

Ivahew [28]

Answer:

x = z - m + y

Step-by-step explanation:

Given:

$\displaystyle \large{z = m+x-y}$

To solve for x-term, we have to isolate it. We can do by subtracting m-term both sides and add y-term both sides.

$\displaystyle \large{z-m+y=m+x-y-m+y}\\\\\displaystyle \large{z-m+y=x}\\\\\displaystyle \large{x=z-m+y}$

Therefore, the answer to this question is x = z - m + y

Please let me know if you have any questions regarding my answer or explanation!
