Sum of two numbers = 15 (Addition)

Difference of two numbers =3 (Subtraction)

Find the two numbers.

What is the product of those two numbers? (Multiplication)

Answers

Answer 1

Answer:

The numbers are  x= 9 and y =6

The product of two numbers

x y  = 9 × 6 = 54

Step-by-step explanation:

Step(i):-

Let x and y are two numbers

Given that the sum of two numbers

 x + y = 15 ..(i)

Given that the difference of two numbers

x - y = 3 ..(ii)

adding (i) and (ii) , we get

x + y + x -y = 15 +3

  2 x = 18

    x =9

Step(ii):-

Substitute x = 9 in equation (i) , we get

x + y = 15

9 + y = 15

     y = 15 - 9

    y = 6

Final answer:-

The numbers are  x= 9 and y =6

The product of two numbers

x y  = 9 × 6 = 54

Use the drawing tools to graph the solution to this system of inequalities on the coordinate plane.
y> 2x + 4
x+y s6

Answers

The inequalities y > 2x + 4 and x + y ≤ 6 can be plotted on the coordinate plane as shown in the picture.

What is inequality?

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have two inequalities:

y > 2x + 4

x + y ≤ 6

We can plot the above inequality on the coordinate plane.

The inequalities representing the region between the two lines the lines are:

y = 2x + 4

x + y = 6

y > 2x + 4  (dashed line on the graph)

x + y ≤ 6     (solid line on the graph)

Thus, the inequalities y > 2x + 4 and x + y ≤ 6 can be plotted on the coordinate plane as shown in the picture.

I'll give brainliest if correct/Maria, Jose, and Trey sent a total of 124 text messages over their cell phones during the weekend. Jose sent 3 times as many messages as Trey. Trey sent 9 fewer messages than Maria. How many messages did they each send?​

Answers

Answer:

Maria sent 32 messages

Jose sent 69 messages

and Tray sent 23 messages

Step-by-step explanation:

m = Maria

j = Jose

t = Trey

m+j+t = 124

j = 3t

t+9 = m $\Rightarrow$ t = m - 9

By substituting the value of t (third equation) into the second equation, we get:

j = 3(m - 9) = 3m - 27.

Finally, by sticking in the values of j, and t we just found out into the first equation, we get:

m + (3m - 27) + (m - 9) = 124

4m - 27 + m - 9 = 124

5m - 36 = 124

5m = 160

m = 32.

So, j = 69,

and t = 23.

A combination lock has 7 digits. How many distinct combinations does this lock have if the numbers used have to be 0 through 5

Answers

Answer:

279,936

Step-by-step explanation:

Since there are 6 options for every digit, and seven digits

So,

6^7=279,936

The total number of  distinct combinations for making 7 digits lock is 2,79,936.

What is permutation?

A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.

Formula for permutation with repetition:

[tex]nP_{r} =n^{r}[/tex]

Where,

P is the total number of combinations.

n is the total number of items in a set

r is the total number of items to be selected from the set

According to the given question.

We have to form a lock that has 7 digits by using numbers from 0 to 5.

Total numbers of items in a set = 6

and total number of items to be selected = 7

Since, we have to form a lock of 7digits but we have only 6 digits. So we have to repeat this numbers so that we can form a 7 digit lock.

Therefore, the total number of combinations for making 7 digits lock is given by

[tex]6P_{7} = 6^{7}[/tex]

⇒[tex]6^{7}=2,79,936[/tex]

Hence, the total number of  distinct combinations for making 7 digits lock is 2,79,936.

56 = -10 + 2x

Answers

56=-10+2x
Move the variable towards the left side and transition it’s sign in this problem
-2x+56=-10
Move the constant heading towards the right side and proceed to put a transition within it’s sign
-2x=-10-56
Now that you have that installed, you must calculate the difference here
-2x=-66
Now you divide -2 in both sides that has taken place in
x=33, therefore x=33 in 56=-10+2x

To check you can do 56=-10+2(33) and it will give you the right answer

A bacteria grows exponentially so that it doubles every 12 days. There are 500 bacteria initially. Write a function that models the number of bacteria after t days.

Note is is NOT doubling every day! Careful.

Find the number of bacteria after 60 days.

Answers

Answer:

16000 bacteria after 60 days

Step-by-step explanation:

60 divided by 12 = 5

500 x 2= 1000

1000 x 2 = 2000

2000 x 2 = 4000

4000 x 2 = 8000

8000 x 2 = 16000

The function is, f(x) =  2x/12*t

And, the number is 16000 bacteria after 60 days.

What is function?

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.

here, given that,

A bacteria grows exponentially so that it doubles every 12 days

let, initially the number of bacteria = x

after 12 days = 2x

i.e. after t days = 2x/12*t

So, the function is, f(x) =  2x/12*t

Now, we have,

60 divided by 12 = 5

So, the number of bacteria will be,

500 x 2= 1000

1000 x 2 = 2000

2000 x 2 = 4000

4000 x 2 = 8000

8000 x 2 = 16000

Hence,   the number of bacteria after 60 days is 16000.
