Answer:

Rate of change = 150%

Rate of change = 100%

Rate of change = 100%

Step-by-step explanation:

Find:

Rate of change

x=2 and x=5

x=3 and x=6

x=2 and x=4

Rate of change = [(5-2)/2]100

Rate of change = 150%

Rate of change = [(6-3)/3]100

Rate of change = 100%

Rate of change = [(4-2)/2]100

Rate of change = 100%

Mrs travis wants to have the clown deliver balloons to her secretary's office. Clowns R Fun charges $1.25 per balloon and $6 for
marysya [2.9K]

The <em>correct answer</em> is:


6 balloons.


Explanation:


Let x represent the number of balloons purchased.


We will call the function for Clowns R Fun c(x):

c(x) = 1.25x+6


We will call the function for Singing Balloons s(x):

s(x) = 1.95x+2


We want the amount for Clowns R Fun, c(x) to be less:

c(x) < s(x)

1.25x+6 < 1.95x+2


Subtract 1.25x from each side:

1.25x+6-1.25x < 1.95x+2-1.25x

6 < 0.7x+2


Subtract 2 from each side:

6-2 < 0.7x+2-2

4 < 0.7x


Divide each side by 0.7:

4/0.7 < 0.7x/0.7

5.7 < x

x > 5.7


She must buy more than 5.7 balloons; the next integer up is 6. She must buy 6 or more balloons.

3(x-4) = x + 14<br> How do you solve this equation
Dmitry_Shevchenko [17]

Answer:

x=13

Step-by-step explanation:

you have to isolate the variable

3(x-4)=x+14

distribute

3x-12=x+14

subtract 14 from each side

3x-26=x

subtract 3x from each side

-26=-2x

divide each side by -2

13=x

flip sides

x=13

hope this helps!!! :)
