What is the value of x in the solution to the following system of linear equations? y=x-1 y=2x+1 –3 –2 –1 0

The value of x in the solution to the given system of linear equation is x = -2

Step-by-step explanation:

The system of equations is given to be :

y = x - 1 (1)

y = 2x + 1 (2)

We need to solve both of these equations.

So, Putting y = x - 1 from equation (1) into equation (2)

⇒ x - 1 = 2x + 1

⇒ -x = 2

⇒ x = -2

Also, y = x - 1

⇒ y = -2 - 1

⇒ y = -3

Hence, The value of x in the solution to the given system of linear equation is x = -2

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
