Answer:
D
Step-by-step explanation:
If you are told that the slope is 2 that means that the equation cannot be A.
The slope is the number in front of the x. So far what you know is that
y = 2x + b
b is found from the given point.
- 7 = 2*(-8) + b Expand the right side
- 7 = - 16 + b Add 16 to both sides
- 7+16 = -16 + 16 + b
- 23 = b
answer y = 2x + 23
The answer is D

Answer:
Step-by-step explanation:
Let chocolate bar = c and blow pops = b
<u>As per given we have equations below:</u>
- 5c + 8b = 23.25
- 2c + 13b = 21.55
<u>13 times the first equation minus 8 times the second to eliminate b and find c:</u>
- 13(5c + 8b) - 8(2c + 13b) = 13(23.25) - 8(21.55)
- 65c - 16c = 129.85
- 49c = 129.85
- c = 129.85/49
- c = 2.65
Each chocolate bar costs $2.65
