I'm not sure what your variables are, but I will try task 3 with you.

y=$500(in billions)

x= the number of years that have passed since 2009

percentage of decrease: 1 - % =

so your formula will look like this: y(1 - %)^x

Please help it’s algebra!!!!!!
babymother [125]

Answer:

a). -6x³ - 12x²    b). -12     c). 12

Step-by-step explanation:

a). (g x f)(x) can also equal f(g(x))

= f (2x +4)

= -3x² (2x+4)

= -6x³ - 12x²

b). f(g(-1))

g(-1) = 2(-1) + 4

= -2 + 4

= 2

f(2) = -3x²

= -3(2)²

= -12

c). g(h(3))

h(3) = 3x-1/2

= 3(3) - 1 / 2

= 4

g(4) = 2x + 4

= 2(4) + 4

= 12

Determine what Descartes’ Rule of Signs says about the number of positive real roots and negative real roots for the polynomial
Allushta [10]

Answer:

Descarte's rule says that the polynomial will have the number of zeroes equal to the number of times  the sign off the coefficient changes.

For positive real roots:

P(x)=9x^3-4x^2+10

The coefficient of polynomial is:

+9 -4 +10

There is 2 time sign in changing in 1st and 2nd term and then in 2nd and 3rd term.

So,there will be 2 positive  real roots or less but even.

For negative real roots  find P(-x)

P(-x)=-(9x^3-4x^2+10)

P(-x)=-9x^3+4x^2-10

So, coefficient of above polynomial is:

-9 +4 -10

There is 2 time sign in changing in 1st and 2nd term and then in 2nd and 3rd term.

So,there will be 2 negative real roots or less but even.
