x² + 3x - 5 = 0 ✓

x² - x = 3x + 7 ✓

5x - 7 = 0 X

7x² + 14x = 0 ✓

x³ - 3x² + 1 = 0 X

x - 5 = 9x + 7 X

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 1
erik [133]
The first thing you should know for this case is how many years there are from 1997 to 2014.
 The number of years is:
 x = 2014-1997 = 17
 Then, you must replace this value in the given equation:
 y = 1.28e ^ 1.31x
 y = 1.28 * e ^ (1.31 * (17))
 y = 6011018736
 answer:
 the number of camera phones shipped in millions in 2014 is
 y = 6011018736

Mell is twice as old as Jerry. If 16 is subtracted from Mell’s age and 16 is added to Jerry’s age, their ages will be equal. Wha
irga5000 [103]

Answer:


Step-by-step explanation:

Let J = Jerry's age

Let M = Mary's age = 2J

 

M - 16 = J + 16

 

Substitute 2J for Mary's age

 

2J - 16 = J + 16

2J - J - 16 = 16

J = 16 + 16

J = 32

 

Jerry is 32.

Mary is twice as old as Jerry.

Mary is 2(32) = 64
