Answer:
The solution is (1,2)
Step-by-step explanation:
- 2x - y = - 4
x + 2y = 5
Multiply the second equation by 2 so we can eliminate x
2( x + 2y) = 5*2
2x +4y = 10
Add this to the first equation
- 2x - y = - 4
2x +4y = 10
----------------------
3y = 6
Divide each side by 3
3y/3 = 6/3
y = 2
- 2x - y = - 4
x + 2y = 5
Multiply the first equation by 2 to eliminate y
2(- 2x - y) = - 4*2
-4x -2y = -8
Add this to the second equation
-4x -2y = -8
x + 2y = 5
------------------
-3x = -3
Divide by -3
-3x/-3 = -3/-3
x = 1
The solution is (1,2)

answer is 4^6</span>
5x+3y=17
3y=-5x+17
y=-5/3y + 17/3
Graph if it asks.
The standard deviation is the square root of the variance
so if the variance is 196, then the standard deviation is the sqrt of 196, which is 14
Answer:
3600 steps
Step-by-step explanation:
Step 1: Multiply 45 by 8000.
Step 2: Move the decimal point two places to the left.
Therefore, the answer is 3600 steps.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
