Answer:
Step-by-step explanation:
<u>Line 1</u>
- -3x + 5y = -4
- 5y = 3x - 4
- y = 3/5x - 4/5
<u>Line 2</u>
- px + 25 y = 4
- 25y = -px + 4
- y = -p/25x + 4/25
<u>The system is inconsistent if slopes are same, so we should have:</u>
- 3/5 = - p/25
- 25*3/5 = -25p/25
- 15 = -p
- p = -15
Answer:
$3
Step-by-step explanation:
You buy 10 pounds of bird seed at store A for $11.50 which means every pound is $1.15.
15 pounds of bird seeds store B for $19.50 is $1.30 per pound.
At store A = 20 * $1.15 = $23
At store B = 20 * $1.30 = $26
So, 26 - 23 = 3
