Kitty [74]

Answer:

A. yes, the data represents a function because u have no repeating x values. A function cannot have repeating x values...they can have repeating y values, just not the x ones

Step-by-step explanation:

B. table : (8,8)(12,12)(14,16)(16,16)

               look at ur points...when x = 8, y = 8...so the table, when x = 8 has a

               value of 8

relation : f(x) = 8x - 5....when x = 8

             f(8) = 8(8) - 5

             f(8) = 64 - 5

             f(8) = 59....and the relation has a value of 59

Therefore, the relation has a greater value when x = 8 <==

C. f(x) = 8x - 5...when f(x) = 19

    19 = 8x - 5

     19 + 5 = 8x

    24 = 8x

    24/8 = x

    3 = x <==

The area of a rectangular parking lot is 7081 m²
Lubov Fominskaja [6]

Step-by-step explanation:

So the question is easy ....The thing that you need to do here is ...You should divide area by length....and you will get your answer....

  • Area of square = l²
  • Area of rectangle = l × b

Area of rectangular parking lot = 7081 m²

length of parking lot = 97 m

Width = ?

Now,

Area = l × b

7081 = 97 × b

7081 / 97 = b

b = 73 m

Hence the width is 73 m....

Vanessa wants to determine the perimeter around her garden. She makes an small model of her garden and combines all the sides: 3
son4ous [18]

Answer:

4

Step-by-step explanation:

since it's all addition, we can remove the parentheses

3x + x + 10 + 5x + 2x + 2 = 56

Now we combine like terms

3x+x+5x+2x+10+2=56

11x+12=56

We subtract both sides by 12 to get,

11x=44

now we divide both sides by 11

x=\frac{44}{11}

x=4
