Answer:

A. x=5,y=6

Step-by-step explanation:

Add y to both sides of the equation.

x=−1+y

x−3y=−13

Replace all occurrences of x with −1+y in each equation.

−1−2y=−13

x=−1+y

Solve for y in the first equation.

y=6

x=−1+y

Replace all occurrences of y with 6 in each equation.

x=5

y=6

The solution to the system is the complete set of ordered pairs that are valid solutions.

(5,6)

The result can be shown in multiple forms. Equation Form: x=5,y=6

Answer:

I think it might be Fatima who did it correctly.

Step-by-step explanation:

You want to find the point where the lines intersect. In this case, the lines intersect at (-1, 6).

Required Data :

1 3/4, 2 1/2, 2, 2 3/4, 1, 1 3/4, 1 1/4, 3, 3 1/4, 3 3/4, 2, 2

Answer:

Julie is Incorrect

Step-by-step explanation:

Given the data:

1 3/4, 2 1/2, 2, 2 3/4, 1, 1 3/4, 1 1/4, 3, 3 1/4, 3 3/4, 2, 2

Arrangement in ascending order :

1, 1 1/4, 1 3/4, 1 3/4, 2, 2, 2, 2 1/2, 2 3/4, 3, 3 1/4, 3 3/4.

The least amount of time spent is : 1

The most amount of time spent is : 3 3/4

From Julie's assertion, that the most amount of time spent is equal to 1 1/2 the least amount of time spent.

Most amount of time = 1 1/2 * least amount of time

3 3/4 = 1 * 1 1/2

15/4 = 3/2

However, 15/4 ≠ 3/2

Hence, Julie is incorrect

Answer:  a) see the graph below

               b) n > 24/5  or 4.8

Step-by-step explanation:

a) see the graph below.

-2 is smaller and equal to x, so the point is close circle; and 3 is only greater than x, so it only has open circle, and the line was between the range from -2 to 3.

b) 5n + 3 >27

           5n > 24   [Subtradt 3 from both side]

             n > 24/5   or 4.8

Answer:

Step-by-step explanation:

1. sin 30 = x/16

   x= 16 sin 30

   x = 8

2. cos 60 = 22/x

   x = 22/cos 60

   x = 44

3. tan 45 = x/19

  x = 19 tan 45

   x= 19

4. tan 16 = x/13

   x = 13 tan 16

   x= 3.73

5. sin 54 = x/45

  x = 45 sin 54

  x= 36.41

6. sin 35 = z/23

 z =   23 sin 35

  z = 13.19

Answer:

33 dogs

Step-by-step explanation:

By taking the 22 cats and dividing it by the ratio. Then multiply that quotient by the ratio of dogs.

Thus:

22/2 = 11

11*3 = 33

There will be 33 dogs.

Hope This Helps :)

Answer: 33

Step-by-step explanation:

2cats = 3dogs

22cats = x

Cross multiply

2x = 3×22

2x = 66

x = 66/2

x = 33

Using a system of equations, it is found that the two consecutive numbers can be 8 and 9, or 3 and 4.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the numbers are consecutive, hence they are n(smaller number) and n+1(larger number).

The square root of the bigger number is 5 less than the smaller number, hence:

[tex]\sqrt{n+1} = n - 5[/tex]

[tex](\sqrt{n+1})^2 = (n - 5)^2[/tex]

[tex]n^2 - 10n + 25 = n + 1[/tex]

[tex]n^2 - 11n + 24 = 0[/tex]

[tex](n - 8)(n - 3)[/tex]

The solutions are n = 8 and n = 3. Hence, the consecutive numbers can be 8 and 9, or 3 and 4.

f(x) = x² + 14      g(x) = x - 2      -1 ?   I think it means evaluate when x = -1

Find (f(x) + g(x))  when x = -1

 (f(x) + g(x))  =   [ ( x² + 14)  +  (x - 2)]        insert f(x)  and g(x)

                    =   [ x² + x + 14 - 2]               add like the term

 (f(x) + g(x))  =   x² + x + 12

(f(-1) + g(-1))  =   (-1)² + (-1) + 12             evaluate at x = -1

                   =    1 - 1 + 12

========================================================

Explanation:

We'll make x the value of last month's phone bill. So if lets say x = 50, this means that last month's phone bill was $50. We don't know yet if x = 50 is the actual solution or not.

We're told that "This month's cell phone bill was for $15.27 more than last month's cell phone bill". This means this month's bill, in terms of x, is x+15.27 dollars. Whatever x is, we add 15.27 onto it getting this month's bill. This works because x is really a placeholder for a number.

Going back to x = 50, that would mean this months bill is x+15.27 = 50+15.27 = 65.27 dollars. We can see that we don't reach 72.50 that we're told the current months bill actually is. Since we don't have a match, this means x = 50 is too small. We can guess and check our way to hopefully land on the answer. However, using algebra is the most efficient method.

----------

The equation we need to solve is:   x+15.27 = 72.50

This is because x+15.27 represents this month's bill and so does the 72.50, as your teacher gave in the instructions.

To solve this equation, we'll undo the "plus 15.27" to isolate x fully. The opposite of addition is subtraction. We'll subtract 15.27 from both sides

x+15.27 = 72.50

x+15.27-15.27 = 72.50-15.27

x = 57.23

Last month's phone bill was $57.23

As a check, adding 15.27 onto last month's bill should get us to 72.50

x+15.27 = 57.23+15.27 = 72.50

It works out, so we've confirmed the answer.

Step-by-step explanation:

The computation of the number of sweets they do have altogether is as follows:

Let us assume Charlie sweets be x

So bilal sweets is 4x

Now Bilal gives Charlie 15 of his sweets due to which they must have the same amount

4x - 15 = x + 15

4x -x = 15 + 15

3x = 30

x = 10 = Charlie sweets

Bilal sweets = 4x = 4(10) = 40

So the total no of sweets held by them is 50
