Answer:
1. 8x + 2y = 16
Step-by-step explanation:
3x - 12y = 10
12y = 3x - 10
y = 1/4 x - 5/6 .... slope: 1/4
perpendicular line slope: -4
8x + 2y= 16
2y = -8x + 16
y = -4x + 8 .... slope: -4
Answer:
either a or c

im sorry if they are both incorrect
Answer:
30%
Step-by-step explanation:
If the price went up to 65 from 50, that is an increase of 15. 15 is 30% of 50.
First you multiply the two equations, equaling 3000000 kg and 60000 kg respectively. Once you have those numbers, you divide the Oakland mass by the Mapleville mass, so 3000000/60000. The answer is 50, to the tree is B, 50 times as big.
X/6.2=-2.1
multiply both sides by 6.2
x=-13.02
