22  True  For all real Numbers A and B,  A  -   B   =    -B   +  A

23  True   For all real Numbers  P, Q, and R, P  -  Q  - R  =  P - R  - Q

24) True For all real Numbers  X, Y, Z and (X   +  Y )  +  Z  =  Z   +  (X  +  Y)

25) False  For all real Numbers M and N,  M/M * N = N/N ==> Example: 5/5  *  3  ≠   3/3  *  5

26) Examples:

Counterexamples =====>   5  - 0  = 5;   5/1   =  5  

5   -  3   ≠  3    -   5;   (5 -  3 )  -    2  ≠   5  -  (3   -  2 );    

6/3    ≠   3/6;   (24/6 )/2   ≠   24/ (6/ 2 )



Hope that helps!!!!                                         : )

the concentration of a drug in a patient's bloodstream t hours after the drug was administrated presented by the equation c(t) =
Andrews [41]

The graph of the function has no asymptotes.

<h3>The table of values of c(t)</h3>

The function is given as:

c(t) = 5t - t² + 1

When t = 1, 2, 5, 10;

We have:

c(1) = 5(1) - 1² + 1 = 5

c(2) = 5(2) - 2² + 1 = 7

c(5) = 5(5) - 5² + 1 = 1

c(10) = 5(10) - 10² + 1 = -49

So, the table of values is

t        c(t)

1         5

2        7

5        1

10      -49

See attachment for the graph of the function

<u>The domain</u>

From the question, we understand that t represents time.

  • Time cannot be negative i.e. t ≥ 0
  • The time does not exceed 5.2 i.e. t ≤ 5.2

So, the domain is 0 ≤ t ≤ 5.2

<u>The range</u>

From the graph, the maximum of the graph is 7.25

So, the range is 0 ≤ f(t) ≤ 7.25

<u>Asymptotes</u>

From the graph, we can see that the graph has no asymptotes.

2. The senior class is having a fundraiser to help pay for the senior trip. Selling a box of chocolates yields a profit of $2.45
BaLLatris [955]

Answer:

Step-by-step explanation:

350 chocolate     1599 of cookies

Step-by-step explanation:

c= box of chocolates

k=box of coockies

k< 550+3c , so   k-3c<550              

 k+c< 1950

 k-3c<550

I will multiply  the second by 3

k -  3c <  550

3k +3c <  5850

ADD BOTH

4k  <  6400

k  <   1600    Cookies should be less than 1600

Since cookies yield more than chocolates , to maximize profit they need to sell the maximum amount of cookies they can

1599 +350= 1949  (less than 1950)

The amount of cookies produced must be no more than 550 boxes plus 3 times the number of chocolates produced.

1599< 3(350) +550= 1050+550=1600)

1599<1600

1599 is at least double of 350 (it could be more than double)
