Which equation below does NOT represent a function of X A) x=y^2 B) y=x C) y = |x| D) y=x^2 E) y=1

vlabodo [156]

Answer:

A) $x = y^{2}$

Step-by-step explanation:

An equation is a function of $x$ when $x$ is the independent variable, that is:

$y = f(x)$ (1)

Where $y$ is the dependent variable.

According to this, $x = y^{2}$ does not represent a function of $x$ , since the independent variable is a function of $y$ , that is, $x = f(y)$ . Therefore, the correct answer is A.

The perimeter of a rectangle is 61 feet. The length is 5 more than twice the width. What is the length and width?

DochEvi [55]

Answer:

Length = 22 feet Width= 8.5 feet

Step-by-step explanation:

Perimeter= 61

Let Width= x

Length= 2x+5

Perimeter= 2l + 2w

61= 2(2x+5) + 2x

61 = 2(2x+5+x)

61/2 = 3x+5

30.5 -5 = 3x

25.5 = 3x

25.5/3 =x

x= 8.5

Hence, width = 8.5 feet

Then, the length = 2x+5 = 2(8.5) +5 = 22 feet

Hope this helps!
