Answer:
Top row: [1 0 0 | 650}
Middle row: [0 1 0 | -400]
Bottom row: [0 0 1 | -1100]
Step-by-step explanation:
When you put an augmented matrix in RREF for, you have to have only 1's diagonal and 0's everywhere else on the left side of the bar.
Simplify 5x-3-7 to -2x-3
-2x-3=15-x
Add 2x on both sides
−3=15−x+2x
Simplify 15-x+2x to 15+x
−3=15+x
Subtract 15 on both sides
-3-15=x
Simplify -3-15 to -18
-18=x
X=-18
The answer is thirtyfour.
Hello there,
Slope:
6 - (-5) / -6 - 0
11/-6
<em>Slope=</em> -11/6
<em>Slope intercept form: </em>y = mx + b
-5 = -11/6(0) + b
-5 = b
Answer: y = -11/6x - 5
Hope I Helped!
