Answer 1

Answer:

3.95

Step-by-step explanation:

R = 7.9/2 = 3.95

Answer 2

Answer:

Step-by-step explanation:

rate of change is the slope of the line

plot the data and calculate the slope or simple find the delta cost divided by the delta people

    (cost x - cost y) / (people x - people y)  = rate of change

you can pick any cost as long as you use the coresponding people

    (19.75 - 7.90) / (5 - 2)  = rate of change

    ( 11 .85) / (3)   = rate

     3.95 = rate

try it for different cost and people and see if you get the same rate, it looks linear to me

Which equation best represents the graph?

Answers

Answer:

The third one

Step-by-step explanation:

The graphs in the reversed shape of a cup are the graphs of quadratic equations whose coefficient of

x^2 is negative.

So, the answer must be either the first or the third.

It can be seen that when x= -4, y becomes 5.

Substituting the value of x, the third equation gives the value 5.

So, the answer is the third one.

Carran is building a fence around his rectangular yard. The fence will cover the front and the 2 sides of the yard. The
front of the yard is 4 feet more than twice the length of one side of the yard. The sides of the yard are the same length. If
the perimeter of the yard is 80 feet, what are the dimensions of the fence?

Answers

9514 1404 393

Answer:

sides: 12 feetfront: 28 feet

Step-by-step explanation:

Let x represent the length of one side of the yard. Then the width of the yard is 2x+4, and the perimeter is ...

  P = 2(L +W) . . . . . . . . . . formula for perimeter of a rectangle

  80 = 2(x + (2x+4)) . . . . . with values from the problem filled in

  40 = 3x +4 . . . . . . . . divide by 2, collect terms

  36 = 3x . . . . . . . . . subtract 4

  12 = x . . . . . . . . . divide by 3. This is the length of the side fence.

  2x +4 = 2(12) +4 = 28

The fence is 12 feet on the sides and 28 feet on the front. (Its total length is 52 feet.)

The volume of a solid is 12 in cubed. If the solid is enlarged
proportionally so that its side lengths increase by a factor of 2,
what is the volume of the enlarged solid?

The square of a number x is 16 more than six times the number
Form an equation in x and solve it.​

Answers

Answer:

x= 8

Step-by-step explanation:

x^2 = 6x+16

TAKE RHS OVER TO LHS TO EQUATE IT TO 0

x^2 - 6x - 16 = 0

FACTORISE

(x-8)(x+2) =0

Therefore

x-8= 0 or x+2= 0

x= 8 or x= - 2

Sub and see which works

8^2 = 6(8) + 16

64= 64

-2^2 = 6(-2) + 16

-4= 4

So the answer must be

x= 8
