Let x = months

so we know that price of software package is $20
Now we need to find x the price of one month

we know that Angie and Kenny spent 115 total

Angie: 20 + 3x ( one software pack + 3(price of one month)
Kenny: 20+ 2x ( one software pack + 2( price of one month)

So Angie + Kenny = $ 115

20 + 3y + 20 + 2y = 115

combine like terms and solve for x. That will give you the cost of one month

40 + 5x = 115
-40 -40

5x= 75
5x/5 = 75/5

x=15

Bumek [7]

Answer:

A. You may set the variables in either order. But for argument sake, let's set as follows:

x = Amount of bookshelves

y = Amount of tables

B. Because of the amount of things you need to make, the following is an inequality using those variables.

x + y > 25

Plus you can determine a second inequality based on the amount of money that you have to spend.

20x + 45y < 675

Finally you may also add in that each value must be greater than or equal to zero, since they cannot have negative tables.

C. By solving the system and looking at basic constraints when graphed, you can see the feasible region has 4 vertices.

(0,0)

(18, 7)

(0, 15)

(33.75, 0) or (33, 0) if you insist on rounding.

Step-by-step explanation: Good luck and hope this helps :)

Which variable is most important to the following problem? At 9:00 a.m., a wind speed of 20 miles per hour was recorded. After t
slavikrds [6]

Answer:

option-C

Step-by-step explanation:

We are given

At 9:00 a.m., a wind speed of 20 miles per hour was recorded

So, initial wind speed =20 miles per hour

Each measurement showed an increase in wind speed of 3 miles per hour

The strongest wind was recorded at 4:00 p.m

so,

top wind speed = initial wind speed + ( total number of hours between 9:00 am and  4:00 pm)*(change in wind speed)

top wind speed = 20 mph+(16-9)*3

=20+7\times 3

=41 miles per hour

Since, change in wind speed and initial wind speed are constant

but the number of hours it took for the wind speed to reach its minimum for the day can be changed

so, most important variables is

the number of hours it took for the wind speed to reach its minimum for the day can be changed

Answer:

13) x = 10

14) x = 22

15) x = 12

16) x = -15

Step-by-step explanation:

13) 4x+5x=9x;90/9=10

14) 45-1=44;44/2=22

15) 37-1=36;36/3=12

16) -54+26=-28;x-28=3x+2;x=-15

Graph A represents the exponential equation y=4(6) and graph B represents y=6(4). which statements are true about graph a and gr
PtichkaEL [24]

Answer:

Step-by-step explanation:The following statements are true about exponential functions:

-The domain is all real numbers.

- The input to an exponential function is the exponent.

- The base represents the multiplicative rate of change.

The reason why the other two options are wrong are explained below:

The range of exponential functions is not always includes negative numbers; on the contrary, the range is the set of all positive real numbers.

The graph of an exponential function does not have a horizontal asymptote at x = 0; contrarily, the equation of the horizontal asymptote of the graph of is y = 0, which is the x-axis.
