Just put the coefients in to a matrix
1x-6y-3z=4
-2x+0y-3z=-8
-2x+2y-3z=-14
mulstiply 2nd row by -1 and add to 3rd
divde last row by 2
multiply 2rd row by 6 and add to top one
multiply 1st row by -1 and add to 2nd
divide 2nd row by -3
mulstiply 2nd row by -1 and add to 1st row
divide 1st row by -3
rerange
x=-2
y=-3
z=4
(x,y,z)
(-2,-3,4)
B is answer
22.31 because A= BH where B is base length and H is Height. Multiply 5.25 by 4.25 and you get 22.31
You got the b part wrong. It would be 4B+4C/2=4D
The best and most correct answers among the choices provided by the question are:
<span>▢A. -2x+3y=-15
▢B. y=2/3x-5</span>
y = mx + b. where m is the slope<span> of the line and b is the y-</span>intercept<span> of the line, or the y-coordinate of the point at which the line crosses the y-axis. To write an equation in </span>slope-intercept form<span>, given a graph of that equation, pick two points on the line and use them to find the </span>slope<span>.</span>
I hope my answer has come to your help. God bless and have a nice day ahead!
