The answer to the question is c
Answer:
C and E
Step-by-step explanation:
To answer this question, we plug in the X values of the coordinates into the equation to see if they'll give us the corresponding Y value.
(X, Y)
Example:
Y = 5X
6 != 5 * 3
We do this for every coordinate point. If the problem doesn't make sense, it doesn't fall on the line. Let's test every one of these.
B. (0, 1)
1 != 5 * 0
C. (3, 15)
15 = 5 * 3
D. (4, 2)
2 != 5 * 4
E. (-1, -5)
-5 = 5 * -1
F. (-1, 5)
5 != 5 * -1
* For those who don't know, the != is how to say "not equal to" in computer science.
Answer:
13lbs
Step-by-step explanation:
x = number of pounds of chocolate/lbs
13.20(x) + 3.90(10) = 9.16(x + 10)
13.2x + 39 = 9.16x + 91.6 (x100)
1320x + 3900 = 916x + 9160
404x = 5260
x = 1315/101 = 13.0198.... ⇒ 13lbs
