The unit normal for the given plane is <5,2,-1>.
The equation of the plane parallel to the given plane passing through (5,5,4) is therefore
5(x-5)+2(y-5)-1(z-4)=0
simplify =>
5x+2y-z=25+10-4=31
Answer: the plane through (5,5,4) parallel to 5x+2y-z=-6 is 5x+2y-z=31
The answer is $162 you take the prices of what she bought and add them together which is $73+$38+$64=$180
then you subtract the $180 from $342 which is $342-$180=$162
so the answer is $162
Answer:
I= 84
Step-by-step explanation:
for

since D is the rectangle such that 0<x<3 , 0<y<3

the answer is y=4x-11
use y+1=4x-12
move 1 to negative because move to the other side
so the answer is y=4x-11
