Answer:
10.5
Step-by-step explanation:
because that's it trust me.
(-4,15),(-7,10)
slope = (10 - 15) / (-7 - (-4) = -5 / (-7 + 4) = -5 / -3 = 5/3
there can be 2 answers to this...depending on the point u use...
y - y1 = m(x - x1)
slope(m) = 5/3
using point (-4,15)...x1 = -4 and y1 = 15
now we sub
y - 15 = 5/3(x - (-4)..not done yet
y - 15 = 5/3(x + 4) <=== this is one answer
y - y1 = m(x - x1)
slope(m) = 5/3
using point (-7,10)....x1 = -7 and y1 = 10
now we sub
y - 10 = 5/3(x - (-7)...not done yet
y - 10 = 5/3(x + 7) <=== and here is the other answer
Step-by-step explanation:
<u>Given:</u>
- Lemons - l and apples - a
- a = 35¢, l = 15¢
- Number of apples and lemons = 17
- Cost of lemons and apples = $3.95 = 395¢
<u>System as per question:</u>
- a + l = 17
- 35a + 15l = 395
Or
- a + l = 17
- 0.35a + 0.15l = 3.95
Answer:
The answer is: 8a + 5b - 9
