Answer:
1 is correct
Step-by-step explanation:
3(4x + 5) = 12
12x + 15 = 12
12x = -3
The slope-intercept form: y= mx + b
9x - 7y = -7 |subtract 9x from both sides
-7y = -9x - 7 |divide both sides by (-7)
y = 9/7x + 1
The actual length of train car is: 5 * 13.5 = 67.5 feet

Answer:
Company C
Step-by-step explanation:
Company A sells 12 tigers for $33.24.
Cost per tiger = $33.34 / 12
= $2.78
Company B sells 16 tigers for $44.80. Company
Cost per tiger = $44.80 / 16
= $2.8
C charges $41.10 for 15 tigers.
Cost per tiger = $41.10 / 15
= $2.74
The company that has the best buy is company C that charges $2.74 per tiger
Answer: D
<u>Step-by-step explanation:</u>
x - 2 = 0 --> x = 2
Using synthetic division:
2 | 4 -5 3 -1
|<u> ↓ 8 6 18</u>
4 3 9 17 ← this is the remainder!
Using remainder theorem:
f(x) = 4x³ - 5x² + 3x - 1
f(2) = 4(2)³ - 5(2)² + 3(2) - 1
= 32 - 20 + 6 - 1
= 17
