Answer:
(A) 9
Step-by-step explanation:
Substitute 2 for X
Answer:
y = -4x-6
Step-by-step explanation:
point slope form
y-y1 = m(x-x1)
y--6 = -4 (x-0)
y+6 = -4(x)
solve for y
subtract 6 from each side
y = -4x-6
We will assume A×B = B×A and show that A and B are necessarily the same.
Assume A×B = B×A. Let a ∈ A and b ∈ B. Then (a,b) ∈ A×B. Since A×B = B×A, we have (a,b) ∈ B×A. That is, a ∈ B and b ∈ A. Therefore, a ∈ A implies a ∈ B and b ∈ B implies b ∈ A. So A = B, as we had set out to do.
21/35 in simplest form is 3/5 because you need to find the GCF first, then divide by it. the greatest common factor in this case is 7, so you need to divide 21 and 35 by seven.
21/7=3
35/7=5
3/5
