Answer:
The solution is B) (3, 1).
Step-by-step explanation:
For the system of equations given, there are few different ways to solve. Since the second equation y = 2x - 5 is already solved for 'y', we can use substitution and place the expression '2x - 5' in for 'y' in the first equation and solve:
2x - 5 + 2 = x
We can also solve for 'y' in the first equation and then set the two equations equal to each other:
y + 2 - 2 = x -2 or y = x -2 so, 2x -5 = x - 2
Either way, when we solve for 'x', we get:
2x - 3 = x or -3 = -x, so x = 3
Plugging in the value of 'x' into the second equation:
y = 2(3) - 5 or y = 6 - 5 or y = 1
The ordered pair (x, y) would be (3, 1).
Answer:
R - chart
Step-by-step explanation:
Range chart (R chart) is a control chart used for processes with two or more subgroups to determine if a process is stable or not. It monitors the mean and range of a normally distributed variable simultaneously collected at regular intervals during a given time. It is used when measuring small subgroups between two and ten at regular intervals from a process. Iy is a;so used for constant subgroups.
I could answer this if a picture was provided to show how many tiles are in figure s and figure t
Answer:
Step-by-step explanation:
10 + 2x + 3x = 10 + -3x + 3x Combine like terms: 2x + 3x = 5x -10 + 5x = 10 + ... like terms: 10 + 10 = 20 5x = 20 Divide each side by '5'. x = 4 Simplifying x = 4
