Answer:I think the answer is 6x because
18= 6x3
42= 6x7
30= 6x5
Step-by-step explanation:
18= 6x3
42= 6x7
30= 6x5 And 6x(3x+7x^3+5x^4) it became 18x^2+42x^4+30x^5

Given plane Π : f(x,y,z) = 4x+3y-z = -1
Need to find point P on Π that is closest to the origin O=(0,0,0).
Solution:
First step: check if O is on the plane Π : f(0,0,0)=0 ≠ -1 => O is not on Π
Next:
We know that the required point must lie on the normal vector <4,3,-1> passing through the origin, i.e.
P=(0,0,0)+k<4,3,-1> = (4k,3k,-k)
For P to lie on plane Π , it must satisfy
4(4k)+3(3k)-(-k)=-1
Solving for k
k=-1/26
=>
Point P is (4k,3k,-k) = (-4/26, -3/26, 1/26) = (-2/13, -3/26, 1/26)
because P is on the normal vector originating from the origin, and it satisfies the equation of plane Π
Answer: P(-2/13, -3/26, 1/26) is the point on Π closest to the origin.
I do believe it would be x=30
Answer:
B) A and D
Step-by-step explanation:
Below sea level already implies negative.
And on a number line, it should be -500
