Does the graph represent a function? Please help. Look at photo

Mathematics

Answer:

A function is defined as an operation on a number, which gives only one output for every input

while graphing a function, the x-ordinate denotes the input and the y-ordinate denotes the output of the function

Now, lets look at the graph

for the input value '4' , we notice that there are 2 possible outputs. The output can be either 2.5 or -2.5

Since there are multiple outputs for almost every input, this graph cannot denote a function since a function gives only one output

The Gray family and the Thompson family each used their sprinklers last summer. The water output rate for the Gray family's spri
snow_lady [41]

Answer:

Gray family's sprinkler was used for 40 hours.

Thompson family's sprinkler was used for 35 hours.

Step-by-step explanation:

The Gray family and the Thompson family each used their sprinklers last summer.

Let x= amount of time in hours that the Gray family's sprinkler was used.

Let y = amount of time in hours that the Thompson family's sprinkler was used.

The water output rate for the Gray family's sprinkler was 40 L per hour. The water output rate for the Thompson family's sprinkler was 20 L per hour. This means that the combined number of hours that both family's used their sprinklers is 40x + 20y

The families used their sprinklers for a combined total of 75 hours, resulting in a total water output of 2300 L .

This means

x + y = 75

40x + 20y = 2300 - - - - - - - -1

Substituting x = 75 -y into equation 1,

40 ( 75 - y ) + 20y = 2300

3000 - 40y + 20y = 2300

-40y + 20y = 2300 - 3000

-20y = -700

y = 700/20 = 35 hours

x = 75 - y

x = 75 -35 = 40 hours

Use the Pythagorean theorem to explain whether or not 7, 8, and 14 could be the side lengths of a right triangle. Show all calcu
VashaNatasha [74]

Answer:  NOT a right triangle

<u>Step-by-step explanation:</u>

If it is a right triangle, the sum of the squares of the shorter sides must equal the square of the larger side.

7² + 8² = 14²

49 + 64 = 196

    113    = 196     FALSE!

These side lengths do not form a right triangle.

The length of a new rectangular playing field is 6 yards longer than double the width. If the perimeter of the rectangular playi
Andru [333]

Answer:

width = 47

Length = 100

Step-by-step explanation:

The perimeter of the rectangle has the formula

P = 2(L + W)

P = 2L + 2W

Length = 6 yards longer than double it's width.

Mathematically,

length = 6 + 2W

We put this into the formula for perimeter

P = 2(6+2W)+2W

294 = 12+4W+2W

294 = 12+6W

Collect like terms

294-12 = 6W

282 = 6w

Divide through by 6

W = 282/6

W = 47

This is the width

Remember length = 6 + 2(W)

So

Length = 6+2(47)

= 6+94

= 100

Width = 47

L = 100

These are the dimensions
