Can someone please help me answer this problem
Answer:
L(xyz) = ( 1 , 3 , -7 )
L = x + 3y - 7z -3
Step-by-step explanation:
f (x,y,z) = xy + 2yz - 3xz
f (3,1,0) = (3) (1) + 2 (1) (0) - 3 (3) (0)
f (3,1,0) = 3
fx = y - 3z
f (3,1,0) = (1) - 3 (0)
fx = 1
fy = x + 2z
f (3,1,0) = (3) - 2 (0)
fy = 3
fz = 2y - 3x
f (3,1,0) = 2 (1) - 3 (3)
fz = -7
Point-slope form is:
y - y1 = m (x - x1)
So the correct form for that equation would be:
y - 4 = 3 (x - 2)
So the correct equation is the first one.
Answer:
3x-5y+11
Step-by-step explanation:
4x-7-4y+18-x-y
4x-x-4y-y-7+18
3x-5y+11
Step-by-step explanation:
a.2x+6=x-4
2x-x=-4-6
x=-10
b.20x-8=18x+6
20x-18x=14
2x=14
x=7
