Answer:
C. -2x+y=1
Step-by-step explanation:
If we move 2x to the other side of the equation, its sign will change from positive to negative.
Step-by-step explanation:
Line AB = sqrt18 = 4.24
Line BC = sqrt10 = 3.16
Line AC = 4
Since the triangle cannot be isosceles or equilateral, the best option here is scalene.
Question 7. y = -2x + 7. y = mx + b; m= slope (-2) (3, 1) resolve for y. you have : 1= -2 (3) + b; 1 = -6 + b; 1 + 6 = b; b = 7.

~Solve by Graphing~
- I graphed the given equations in a program.
- The point of intersection, if the lines pass, would be the solution.
- The point of intersection in the given system of equations is (4,1).
- This means that (4,1) is the solution.
- See the graph attached.

Hope this helps you. I apologize if it’s incorrect.
Finding the difference between the two temperatures, it is found that Regina is 38.7ºC degrees colder in January than in July.
----------------------------
- The mid-afternoon temperature in January is of -12.6ºC.
- In July, it is of 26.1ºC.
- The difference of the temperatures is given by:

From the difference of 38.7ºC, there are two interpretations:
- Regina is 38.7ºC degrees colder in January than in July.
- Regina is 38.7ºC degrees warmer in July than in January.
