Answer:

y=5

Step-by-step explanation:

f(x) =5 is a line with the equation y=5

Question 6

Hello!

I will post the graph of the function y = 1/2tan(x) below.

Using this graph, the answer is false. Why? The graph below is graphed at (π, 0) and (-π, 0), while this graph is not graphed at those points. Therefore, it is false.

The cost of 3 cheese sandwiches and 2 bottles of water is £7.80. The cost of 5 cheese sandwiches and 4 bottles of water is £14.2

s344n2d4d5 [400]

Answer:

sandwiches is £1.8

bottle water = £1.2

Step-by-step explanation:

Given data

let cheese sandwiches be x

and bottle water be y

3x+2y= 7.8------------1

5x+4y= 14.20---------2

solve 1 and 2

3x+2y= 7.8------------1*5

5x+4y= 14.20---------2*3

15x+10y= 39

- 15x+12y= 42.6

-2y = -3.6

y= 3.6/2

x=1.8

Put x= 1.8 in 1

3(1.8)+2y= 7.8

5.4+2y= 7.8

2y= 7.8-5.4

2y=2.4

y= 2.4/2

y= 1/2

Hence cheese sandwiches is £1.8

bottle water = £1.2

Mrs.green needs to store 21 math books on a shelf during school vacation. Each math book is 2.4 centimeters thick. If Mrs.Green

Brums [2.3K]

Each book is 2.4cm thick; that means if you're stacking books on top of each other, that is, on their sides, each book will be 2.4 cm tall. multiply the length of each book (2.4cm) by 21 to figure out how tall 21 books together will be. 2.4 x 21 = 50.4. the shelf needs to be at least 50.4cm tall.

As part of a quality-control program, 4 batteries from a box of 17 is chosen at random for testing. In how many ways can this te

belka [17]

Answer:

This test batch can be chosen in 2380 ways

Step-by-step explanation:

The order in which the batteries are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.
