You would need to change the slope to -6 because perpendicular lines have opposite reciprocal slopes.
Answer:
ez pts tysm
Step-by-step explanation:
- Your answer is no solution.
- Because if we transpose 10x to the left hand side with a change in the symbol, then it will become 0.
- 10x - 1 = 10x +4
- or, 10x - 10x = 4 + 5
- or, 0 = 9
- Hence, the equation has <em><u>no solution</u></em>.
Hope you could get an idea from here.

Yesterday's price of notebook = $3.45
Today's price of notebook = $3.20
We have to determine the percentage decrease in the cost of notebook.
Percentage decrease = (Decrease
Old price) ![\times 100](https://tex.z-dn.net/?f=%5Ctimes%20100)
So, percentage decrease = ![\frac{3.45-3.20}{3.45} \times 100](https://tex.z-dn.net/?f=%5Cfrac%7B3.45-3.20%7D%7B3.45%7D%20%5Ctimes%20100)
=![\frac{0.25}{3.45} \times 100](https://tex.z-dn.net/?f=%5Cfrac%7B0.25%7D%7B3.45%7D%20%5Ctimes%20100)
= 7.246%
= 7.25%
Therefore, there is 7.25% of decrease in the cost of the notebook.
Answer:
a) ![-5x^{2}+3x+27](https://tex.z-dn.net/?f=-5x%5E%7B2%7D%2B3x%2B27)
b) ![-5x^{2}+3x+9](https://tex.z-dn.net/?f=-5x%5E%7B2%7D%2B3x%2B9)
Step-by-step explanation:
a) Let the required polynomial be p(x).
We have the relation,
+ p(x) = 18
i.e. p(x) = 18 ![-5x^{2}+3x+9](https://tex.z-dn.net/?f=-5x%5E%7B2%7D%2B3x%2B9)
i.e. p(x) = ![-5x^{2}+3x+27](https://tex.z-dn.net/?f=-5x%5E%7B2%7D%2B3x%2B27)
b) Let the required polynomial be q(x).
We have the relation,
+ q(x) = 0
i.e. q(x) = 0 ![-5x^{2}+3x+9](https://tex.z-dn.net/?f=-5x%5E%7B2%7D%2B3x%2B9)
i.e. q(x) = ![-5x^{2}+3x+9](https://tex.z-dn.net/?f=-5x%5E%7B2%7D%2B3x%2B9)
