Substitute n with 4 to find d(4):
d(4)=d(4-1)+17
d(4)= d(3)+17=47+ 17= 64
Substitute n with 3 to find d(3):
d(3)= d(2)+17=30+17 =47
Substitute n with 2 to find d(2):
d(2)=d(1)+17= 13+17= 30
The 4th term is 64
A single yard is equivalent to 3 feet. With this information, we find that 2 yards are equal to 6 feet.
A 6 feet piece of copper wire costs $69.60. Divide the total price by the amount of feet to find the price per foot.
The price per foot is $11.60. Let me know if you need any clarifications, thanks!

Both of them could be true, tables and graphs are basically the same thing... is there a photo?
Answer:
Step-by-step explanation:
- Total number of plants = 15
- Total cost = $96
- Cost of pink flowering plant = $8
- Cost of purple flowering plant = $5
<u>Let x and y be the number of plants bought. Then we have equations:</u>
- 8x + 5y = 96
- x + y = 15 ⇒ y = 15 - x
<u>Substituting y in the first equation:</u>
- 8x + 5y = 96
- 8x + 5(15 - x) = 96
- 8x + 75 - 5x = 96
- 3x = 96 - 75
- 3x = 21
- x = 7
Correct option is the second one
