Answer = -11

4(6x+12) = -216
24x+48 =-216
24x = -264
x = -11

Answer: x=-11

Step-by-step explanation:

4(6x+12)=-216 Distribute the 4 in the parenthesis

24x+48=-216

24x=-216

-216 divided by 24

answer= -11

Factor f(x)=x4-x3-7x2+13x-6 completely. Then Sketch the graph
Dennis_Churaev [7]

ANSWER TO QUESTION 1


f(x)=(x-2)(x+3)(x-1)^2.



EXPLANATION


The function given to us is,


f(x)=x^4-x^3-7x^2+13x-6


According to rational roots theorem,


\pm1,\pm2,\pm3,\pm6 are possible rational zeros of  


f(x)=x^4-x^3-7x^2+13x-6.


We find out that,


f(-3)=(-3)^4-(-3)^3-7(-3)^2+13(-3)-6


f(-3)=81+27-63-39-6



f(-3)=6-6



f(-3)=0


Also




f(2)=(2)^4-(2)^3-7(2)^2+13(2)-6



f(2)=16-8-28+26-6



f(2)=6-6



f(2)=0


This implies that  


x-2 and x+3 are factors of



f(x)=x^4-x^3-7x^2+13x-6 and hence (x-2)(x+3)=x^2+x-6 is also a factor.



We perform the long division as shown in the diagram.



Hence,


f(x)=(x-2)(x+3)(x-1)^2.


ANSWER TO QUESTION 2

Sketching the graph

We can see from the factorization that the roots  

x=2 and x=-3 have a multiplicity of 1, which is odd. This means that the graph crosses the x-axis at this intercepts.


Also the root x=1 has a multiplicity of 2, which is even. This means the graph does not cross the x-axis at this intercept.



Now we determine the position of the graph on the following intervals,


x\le -3


f(-4)=(-4)^4-(-4)^3-7(-4)^2+13(-4)-6


f(-4)=150\:>0



-3\le x \le 1


f(0)=-6\:


1\le x\le 2


f(1.5)=-0.56\:



x \ge 2



f(3)=24\:>0



We can now use these information to sketch the function as shown in diagram

A deposit of $10,000 is made into an account that earns 6% interest. Use
Georgia [21]

Answer:

  $19,000

Step-by-step explanation:

The balance is the sum of the principal amount and the interest it earns:

  A = P + I

  A = P + Prt

  A = P(1 +rt)

  A = $10,000(1 +.06×15)

  A = $19,000 . . . balance after 15 years

Answer:

8 hours

Step-by-step explanation:

Equation: y = 7x + 11

67 = 7x + 11

Subtract 11 from both sides;

56 = 7x

Divide both sides by 7;

F(x)=-3x^2+9x-8 Find f(5)
Oxana [17]

Answer:

-38

Step-by-step explanation:

You replace the x with 5.

turns it into -3 (5)^2+9(5)-8

-3(25)+45-8

-75+45=-30-8=-38
