One x-intercept of the graph of the of the cubic function f(x) = x^3 – 2x^2 – 111x – 108 is –9.
katrin2010 [14]

Answer:

The zeros of the given function are -9,-1 and 12.

Step-by-step explanation:

The given function is

f(x)=x^3-2x^2-111x-108

It is given that the x-intercept of the graph is -9, therefore -9 is a zero of the function.

Since -9 is the zero of the function, therefore (x+9) is a factor of f(x). Use synthetics method or long division method to divide the function by (x+9).

f(x)=(x+9)(x^2-11x-12)=0

f(x)=(x+9)(x^2-12x+x-12)=0

f(x)=(x+9)(x(x-12)+(x-12))=0

f(x)=(x+9)(x-12)(x+1)=0

Use zero product property and quote each factor equal to 0.

x=-9,-1,12

Therefore zeros of the given function are -9,-1 and 12.

Mr. Bates and Ms. Psenicska like playing Pokemon. Mr. Bates has 3 packs of cards plus 2 other cards. Ms. Psenicska has 6 packs o
Ivahew [28]

Answer:

The only algebraic expressions we can find here are the ones for the number of cards that Mr. Bates and Ms. Psenicska have.

We know that Mr. Nates has 3 packs of cards, plus 2 other cards.

If each pack of cards has N cards, then the total number of cards of Mr. Nates is:

Mr. Nates = 3*N + 2

And Ms. Psenicska has 6 packs plus other 8 cards, then she has a total of:

Ms. Psenicska = 6*N + 8

These two are the only expressions we can make with the given information.

for her book club, Sharon reads for 45 minutes each day. write an expression for the number of hours she reads in d days
Dafna1 [17]
N=(3/4)*h*d

--------------------

n=Number of hours she reads

h=Hour(s)

d=Days

--------------------

You see, with this formula - when d=2,

n=(3/4)*h*2=(6/4)*h=(3/2)*h=1.5 hours

So, in the space of 2 days, she had spent 1.5 hours reading.
