Answer:
C. y < -1/5x + 1
Step-by-step explanation:
We can eliminate A and B because the inequality sign is incorrect. If we were to graph those, the shaded area would be above the line, not below. We are left with C and D. Notice in our given graph that the line is dotted, so solution on the line are <em>not </em>included. So our answer would be C. because the inequality sign is y is less than and not y is less than or equal to.
Answer: (C) It can be shown that W = x y z ∈ R 3 : x + 2y − 4z = 0 and y − 3z = 0 is a subspace of the vector space R 3 , and the dimension of W is 2.
Step-by-step explanation:
Answer is NO, it does not double.
Step by step.
Equation for surface area (SA) = 2lw+2lh+2wh
If we double the length and width, making them each 2l and 2w, we then have:
2(2l x 2w) + 2(2l x h) + 2(2w x h)
= 2(4lw) + 4lh + 4wh
SA = 8lw + 4lh + 4wh
If the surface area had been doubled, we should get the equation (4lw + 4lh + 4wh) for a doubled surface area.
So no, it is not doubled.
