Which of the following represents a function

Oksana_A [137]

Answer:

(2,3),(4,3),(-2,-3),(-4,-3)

Step-by-step explanation:

A function is defined as a relation in which each domain element (x-value) is paired with exactly one range element (y-value).

This means that each value we input for x must have only one possible output. If the same x-value yields more than one y-value, it is not a function.

The correct answer, as shown above, meets the criteria of a function, as each x-value is shown to produce exactly one y-value. In this set of ordered pairs, if x = 2, then y = 3, and if x = -2, then x = -3.

A set of ordered pairs is not a function if there are ordered pairs with the same x-values but different y-values.

In the other sets of ordered pairs, one x-value has more than one possible y-value. Let's use the last set as an example:

(5,1),(5,2),(5,3),(5,4)

Inputting 5 as x produces four different y values; there is no one y value for the x-value. y could equal 1, 2, 3, or 4.

5.Find the slope of a line perpendicular to

Lemur [1.5K]

Hi there!

When the slopes of two perpendicular lines are multiplied the outcome will be -1.

The slope is the number that is positioned in front of the variable x in the formula. In this case the slope of the given line is -2/5.

Let's call the slope of the perpendicular line m and take into account the given data of the question and my earlier explanation. We then find the following:

$- \frac{2}{5} \times m = - 1$
Divide both sides by - 2/5.

$m = \frac{ - 1}{ - \frac{2}{5} } = 2 \frac{1}{2} = \frac{5}{2}$
The answer is B.

~ Hope this helps you!

X^2/100+y^2/25=1 The length of the major axis is:

Maru [420]

Answer:

Step-by-step explanation:

x^2/100 + y^2/25=1 -----(1)

Since 25<100

Hence the above equation is of the form x^2/a^2+ y^2/b^2=1-------(2)

Comparing (1) and (2)

a^2=100

a=10

Major axis=2a=20

Help please please please

melisa1 [442]

We are given with a rectangle whose length is 27 miles , and breadth is (3y + 1) miles and we are asked to find it's area . As , we know that , the area of a rectangle with Length and Breadth , L and B is given by Area = L × B respectively . Now , using this same formula in our question we have ;

${:\implies \quad \sf Area=27\times (3y+1)}$

${:\implies \quad \sf Area=27\times 3y + 27\times 1}$

${:\implies \quad \bf \therefore \quad \underline{\underline{Area=81y+27\:\: sq\:\: mi.}}}$
