Which graph represents y as a function of x?

Answer:

Bottom left.

Step-by-step explanation:

In order for any of them to be the graph of a function you would need that given a value of x, you get no more than one value of y. Zero is fine, you just picked an x out of the domain.

In layman's terms it means that if you grab a ruler, a piece of paper, a pen, and you scan the graph moving the edge parallel to the y axis (ie, vertically) you are allowed to touch the graph only once. Top right is out. Bottom left is ok, bottom right is not: you have infinite points of contact in there.

Top left would be fine, if it wasn't for x = 1. In there you have two values marked with a solid dot. That makes it not the graph of a function.

Leto [7]

Answer: The mean is the same as the average. In order to find the mean, or average score of the two tests, you need to take the sum of the two tests, and then divide by the number of tests, which is two.

We don't know the score of the second exam. Let it = x

Then we have the following equation:

(88 + x)/2 = 93

88 + x = 2 * 93

88 + x = 186

x = 186 - 88 = 98

You need to score a 98 on the second test

Please i need help When is the product of the square root of a prime number and a nonzero rational number a rational number?

lidiya [134]

Answer:

The product of the square root of a prime number and a nonzero rational number is a irrational number.

Step-by-step explanation:

Given that,

When is the product of the square root of a prime number and a nonzero rational number a irrational number.

We know that,

Prime number :

Prime number is that number whose has a two factor. first factor is one and second is themselves.

The square root of a prime number is irrational number.

Rational number :

Rational number is that number which is in fraction form.

For example : $\dfrac{p}{q}$

Here, p and q are integers

We need to proof the product of the square root of a prime number and a nonzero rational number is a rational number

Using given data

Suppose, the square root = √5

Rational number = $\dfrac{2}{3}$

We need to calculate the product of the square root of a prime number and a rational number

Using formula of product

$R=P\timesQ$

Where, P = square root of a prime number

Q= rational number

Put the value into the formula

$R=\sqrt{5}\times\dfrac{2}{3}$

$R=\dfrac{2\sqrt{5}}{3}$

Hence, The product of the square root of a prime number and a nonzero rational number is a irrational number.
