Answer:
The solution set is (6,3)
Step-by-step explanation:
Begin by multiplying equation 1 by 2. You'll see why in a moment
2y = 2*(1/2) x
2y = x
Substitute this value into equation 2.
2y + 4y = 18 Combine like terms on the left
6y = 18 Divide both sides by 6
6y/6 = 18/6 Do the division
y = 3
To solve for x just use the top equation
y = 1/2x
3 = 1/2x Multiply by 2
3*2 = x
x = 6
This would be 3! ways
= 3*2*1 = 6 ways Answer
Answer:
First one - the root is in the bottom of the fraction (just like it is with trees) and she wrote it backwards. 2 to the four over three is the third root of two the power of four and not the other way around. Just change that and it's good.
Second one - he said that ln(2) = 2 and that's just not true. No way of fixing that one, he shouldn't get high as often as he does I guess.

Answer:
=9:4
Step-by-step explanation:
The relationship between area and side of triangle is
= (S1/S2)^2= (A1/A2)
=(3/2)^2=(A1/A2)
=9/4=(A1/A2)
=A1:A2=9:4
