A) The intersection occurs at the same height 'y', so the y of each equation must be equal:
y=y implies <span>2−x = 8x+4. The solution is -2=9x, x = -2/9=2/3, and y = 20/9
(-2/9,20/9)
</span>
B)
X | Y1 | Y2
_____________
-3 5 -20
-2 4 -12
-1 3 -4
0 2 4
1 1 12
2 0 20
3 -1 28
C) I would draw each line with the values on the table. Where both lines cross is the intersection point. It should be (-2/9, 20/9)
0.57 to the nearest tenth is .6
Answer: 60 miles per hour
Explanation: r = d/t = 420 miles/7 hours = 60 miles per hour.
Hope this helps :)
I'm going to assume that you're asking, "How many 1/3-oz servings are available in 6 oz?"
Divide 6 oz by 1/3 oz:
6 oz
----------------------- = 18 servings
(1/3) oz/serving
