Answer is d. -5/3 because y2-y1 =x2-x1
Answer:
Step-by-step explanation:
The Answer is 20.
1: First, add up all the temperatures that has been provided, 21 + 21 + 19 + 19. It should give you 80.
2: Divide 80 by how many temperatures has been shown. There were 4 temperatures shown, so 80/4 = 20. Hope this helps you!
Answer:
Never
Step-by-step explanation:
If two equations have the same slopes and the same y-intercepts they are equivalent to each other
Here's why:
The formula for a linear equation is y= mx +b
b= y- intercept
m= slope
m and b are only variable that have to be replaced by a number for the equation to be complete
Therefore, when m and b (or the slope and the y-intercept) of both equations are the same, the two equations are the same
The answer would be <em>allrealnumbers, </em>not <em>nosolutions</em>

55% is crackers if the 11 is crackers
For this case we have the following system of equations:
We multiply the first equation by -4:
We have the following equivalent system of equations:
We add the equations:
We find the value of the variable "x":
Thus, the solution of the system is:
