Question

use ur brain with me and tell correct answer​

Answer 1

Answer:

16. pen = x

book= y

then

2x=y

17. genuinely don't know..... sorry

18. zero of polynomial

2x+1=0

x= -1/2. is the zero of given polynomial

19. yes , because there's only one term with a variable in given equation. = 10x^1/2+3

20. supplementary angles are the ones whose sum is equal to 180°

hope it helps...

Answer 2

16. Let cost of book be 'x'

And cost of pen be 'y'

As per the problem;

y= 1/2x

2y=x

2y-x=0

17. Empirical probability uses the number of occurrences of an outcome within a sample set as a basis for determining the probability of that outcome. The number of times "event X" happens out of 100 trials will be the probability of event X happening.

Formula: P(E)= no of times of an event E occurred/ total no of trails

18. Let p(x)= 2x+1

Now take p(x)= 0

2x+1=0

2x= -1

x= -1/2

Therefore the zero of the given polynomial is -1/2.

19. No the given one is not a polynomial and us also not a polynomial in one variable

20. Supplementary angles:

The sum of two angles = 180°
