Answer:

2009

Step-by-step explanation:

The question can be interpreted as:

$f(x) = -1.330x^2 + 5.149x + 5.517$

Required

Determine x when f(x) = 10.5

Substitute 10.5 for f(x) in $f(x) = -1.330x^2 + 5.149x + 5.517$

$10.5 = -1.330x^2 + 5.149x + 5.517$

Collect Like Terms

$-1.330x^2 + 5.149x + 5.517-10.5=0$

$-1.330x^2 + 5.149x -4.983=0$

Using quadratic formula

$x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}$

Where

$a = -1.330$

$b = 5.149$

$c = -4.983$

$x = \frac{-5.149 \± \sqrt{5.149^2 - 4*-1.330*-4.983}}{2*-1.330}$

$x = \frac{-5.149 \± \sqrt{0.002641}}{-2.660}$

$x = \frac{-5.149 \± 0.0514}{-2.660}$

Split:

$x = \frac{-5.149 + 0.0514}{-2.660}\ or\ x = \frac{-5.149 - 0.0514}{-2.660}$

$x = \frac{-5.0976}{-2.660}\ or\ x = \frac{-5.2004}{-2.660}$

$x = 1.92\ or\ x = 1.96$

Both values of x approximates to 2.

So:

$x = 2$

2 years after 2007 is 2009.

Hence, the funding is about $10.5 billion in 2009

Answer:

5x-1

Step-by-step explanation:

f(x) = 3x-2

g(x) = 2x+1

(f+g) (x) = 3x-2 + 2x+1

Combine like terms

= 5x -1

Solve by factoring 6x^2=3-7x

olya-2409 [2.1K]

Step-by-step explanation:

6x^2 = 3 - 7x

Bringing terms on one side

6x^2 + 7x - 3

Finding factors of 18

6x^2 + 9x - 2x - 3

3x(2x + 3) - 1(2x + 3)

(2x + 3) and (3x - 1) are the factors
