7 0

Answer:

x^2 + 2x - 8

Step-by-step explanation:

h(x) + k(x) = (2x^2 + 5x - 12) + (-x^2 - 3x + 4)

Add Like Terms

(2x^2 + 5x - 12) + (-x^2 - 3x + 4)

2x^2 - x^2 = x^2

(2x^2 + 5x - 12) + (-x^2 - 3x + 4)

5x - 3x = 2x

(2x^2 + 5x - 12) + (-x^2 - 3x + 4)

-12 + 4 = -8

x^2 + 2x - 8

love history [14]

(8)(5)=40 laps

2. Hailey raised a total of $2,820, therefore, you can calculate the amount of money donated by each donor (which you can call x) by dividing  $2,820 by 40 laps, as you can see below:

x=\frac{2,820}{40}\\x=70.5

The number of camera phones shipped globally can be modeled by the function y = 1.28e 1.31x where x is the number of years since
OlgaM077 [116]

Answer: 895 phones

Step-by-step explanation:

Given that :

The function : y = 1.28e^1.31x ; is used to model the number of camera phones shipped since 1997

y = number of camera phones ; x = number of years since 1997

The number of camera phones shipped in the year 2002 can be obtained thus ;

x = 2002 - 1997 = 5 years

y = 1.28e^(1.31 * 5)

y = 1.28e^6.55

y = 1.28(699.24417)

y = 895.03254

y = 895 phones
