Answer:

Solution (8 , 17).

Step-by-step explanation:

Given : y = 3x − 7  and y = 2x + 1 .

To find : What is the solution to the system of equations.

Solution : We have given

y = 3x − 7  --------(1)

y = 2x + 1  ---------(2).

Plug the value of y of equation 2 in equation 1.

2x + 1 = 3x - 7.

Subtracting both sides by 1

2x + 1 - 1 = 3x - 7 - 1.

2x = 3x - 8.

On subtracting both sides by 3x.

2x -3x = - 8.

-x = -8

On Dividing both sides by -1

x = 8.

Now plug the x = 8 in eq 1.

y = 3(8) -7.

y = 24 - 7.

y = 17.

Solution (8 , 17).

Therefore, Solution (8 , 17).

8 was dividedby some numberthen added to13.next this difference was multiplied by 2 which gave a product of 30 find the answer
Anna11 [10]
The answer is 4. 

8/x +13 = y        -------->  y * 2 = 30 

divide 2 on both sides so y = 15

8/x + 13 = 15 
      - 13     - 13 

8/x = 2 

x =4

Please help me I really need this and show your work if possible
kogti [31]
The temperature at 9 am was -11 degrees.

We know that at 5 am, it was -7 degrees. Since the change of temperature is a negative number, then we subtract the absolute value of the change from -7. -7 - 3 = -10. Following this pattern, we then have:
-10 - 2 = -12 (6 am - 7 am)
-12 - 5 = -17 (7 am - 8 am)
-17 + 6 = -11 (8 am - 9 am, added since it was a positive change of temperature)

And our final answer is -11 degrees Fahrenheit.

Approximately how many more job openings are expected for security guards than pharmacy technicians?
Illusion [34]

Answer: c. 21,000

Step-by-step explanation:

Since, by the given diagram,

The approximate number of security guard job opening = 39,000

And, the approximate number of pharmacy technicians job opening = 18,000

Hence, the difference of the number of security guard job opening and the number of pharmacy technicians job opening = 39,000 - 18,000 = 21,000

Thus, the job openings for security guards is approximately 21000 greater than that of pharmacy technicians.

⇒  Option C is correct.
