A sales manager for an advertising agency believes that there is a relationship between the number of contacts that a salesperso
serg [7]

Using variable concepts, of dependent and independent variables, it is found that the dependent variable is the amount of sales dollars earned.

<h3>What is the relation between a function and the dependent and independent variables?</h3>

  • A function has the following format: y = f(x).
  • In which each value of y is a function of one value of x, and thus, <u>x is the independent variable and y is the dependent variable</u>.
  • That is, the input of the function is the independent variable and the output is the dependent variable.

In this problem, the manager believes that the amount of sales dollars earned is a function of the number of contacts that the salesperson makes, hence:

  • The number of contacts is the independent variable.
  • The amount of sales dollars earned is the dependent variable.

Is (-5,-5) a solution of y&gt;- 2x + 4?
g100num [7]

Answer:

No, (-5, -5) is not a solution

Step-by-step explanation:

<u>Step 1:  Plug in -5 for y and -5 for x</u>

y > -2x + 4

-5 > -2(-5) + 4

-5 > 10 + 4

<em>-5 > 14</em>

<em />

Answer:  No, (-5, -5) is not a solution

The radius of a large sphere is 8 times the radius of a small sphere. the surface area of the large sphere is how many times the
kondaur [170]
Large sphere's radius = R,
small sphere's radius = r, R = 8r
surface area of a sphere (SA) = 4×pi×radius^2
So what we need is the SA of the larger in terms of the smaller sphere, so if:
SA (of R) = 4×pi×R^2, then plug in "8r" for "R"...
SA = 4×pi×(8r)^2 = 4×3.14×64r^2
SA = 12.57×64r^2 = 804 r^2
Therefore the SA of the larger sphere is 804 times the SA of the smaller sphere.
I hope that makes sense!

A party rental company has chairs and table for rent .the total cost to rent 2 chairs and 3 tables is $29 .the total cost to ren
jarptica [38.1K]

Let C = cost to rent each chair

Let T = cost to rent each table

 

4C + 8T = 73

2C + 3T = 28

 

Multiply the 2nd equation by (-2) and then add the equations together  

 

4C + 8T = 73

-4C - 6T = -56

 

2T = 17

T = 17/2 = 8.5

 

Plug this in to the 1st equation to solve for C

 

4C + 8(17/2) = 73

4C + 68 = 73

4C = 5

C = 5/4 = 1.25

 

So the cost to rent each chair is $1.25 and the cost to rent each table is $8.50
