First, multiply $3 by 4 to get $12 spent on cookies. Then, you multiply $12 by 2 to know that the pies cost $24. You then divide the $24 by 3 to get $6 per pie. Meaning, each pie had cost $6. You add the $12 and $24 together to get $36. Finally, you subtract $36 from $40 to know that she only has $4 left.
Answer:
Step-by-step explanation:
<u>Point-slope form: </u>
- <em>y - y1 = m(x - x1)</em>
<u>Slope formula:</u>
- <em>m = (y2 - y1)/(x2 - x1)</em>
<u>Given points:</u>
<u>Finding the slope:</u>
- m = (13 - (-2))/(3 - 0)
- m = 15/3
- m = 5
<u>Using point 1</u>
- y - (-2) = 5(x - 0)
- y + 2 = 5x
Answer:
The answer is C, -6/5
B and D are correct. D is C and A aren't correct because a plane consists of three points.
