It would be going down (0,60)
X^5 + 4x^3 - 5x
= x(x^4 + 4x^2 - 5)
= x (x^2 + 5)(x^2 - 1)
= x( x + 1)(x - 1)(x^2 + 5)
there are 3 real zeroes and 2 complex zeroes.
Answer:
I don't think this is valid.
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
