Step-by-step explanation:
Answer: Second option: (4,0) and (-9,0)
f(x)=x^2+5x-36
The x-intercepts of the graph of a function f(x) are the values of the variable x that makes f(x)=y equal to zero. To find these values we only have to equal f(x)=y to zero:
f(x)=y=0
x^2+5x-36=0
Factoring the polynomial:
(x+9)(x-4)=0
Using that if a b=0, then: a=0 or b=0
with a=x+9 and b=x-4
x+9=0 or x-4=0
Solving for x:
x+9-9=0-9 or x-4+4=0+4
x=-9 or x=4
Then the x-intercepts are the poitns (x,y)=(x,0):
(4,0) and (-9,0)
The fraction of the total books about mammals is 7/18
Let the total number of books in the school be 1 whole , ie 12/12( since we are dealing with fractions)
Number of science books =7/12
Number of mammals books =2/3 of science books
=2/3 x 7/12=14/36 = 7/18
Since the total books are 12/12 which is also =1 whole
Then the fraction of total books that are about mammals are 7/18 x 1 whole =7/18
