Find the range of the given function y = 5x - 4, where x > 6.
statuscvo [17]

Given:

The function is:

y=5x-4

where x>6.

To find:

The range of the given function.

Solution:

Range is the set of output values.

We have, x>6. It means the value of x is greater than 6 but not equal to 6.

The function is

y=5x-4

Putting x=7, we get

y=5(7)-4

y=35-4

y=31

Putting x=8, we get

y=5(8)-4

y=40-4

y=36

Putting x=9, we get

y=5(9)-4

y=45-4

y=41

So, the range of the given function is {31, 36, 41...}.

Therefore, the correct option is B.

Step2247 [10]
Answer = 86.135 squared.

To find the area of this figure the best action would to divide it into three different sections, finding the area of each and then adding them all together.

First, find the area of the square in the center, which would be 60in.

Second, find the area of the half circle. You would use the formula for area of a circle. You would divide this answer by 2 since this is only half of a circle. You would get 14.135in.

Last, you would find the area of the triangle. You would multiply both sides and then divide by 2, since it’s a triangle and not a square. Area for this is 12in.

And then you would add all these together.

A bag contains 9 tiles, each with a different number from 1 to 9. You choose a tile without looking, put it aside, choose a seco
Ksenya-84 [330]

Using the combination formula, it is found that there are 84 ways to choose the three tiles.

The order in which the tiles are chosen is not important, hence the <em>combination formula</em> is used to solve this question.

<h3>What is the combination formula?</h3>

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by:

C_{n,x} = \frac{n!}{x!(n-x)!}

In this problem, three tiles are chosen from a set of nine, hence:

C_{9,3} = \frac{9!}{3!6!} = 84

There are 84 ways to choose the three tiles.
