Answer:

4x - y = -5

Step-by-step explanation:

The equation of a new line which is parallel to old line 4x - y = 14 looks exactly the same as that of the old line EXCEPT that we replace the constant, 14, with C and find C for the line that passes through (-2, -3).

4x - y = 14 becomes 4x - y = C

Now substitutte -2 for x, -3 for y and calculate C:

4(-2) - (-3) = C, or

-8 + 3 = C = - 5

Thus, the new equation is 4x - y = -5

Answer:

see below

Step-by-step explanation:

The recursive function tells you the first term is 1. That is the meaning of ...

$a_1=1$

It also tells you that to find the next term, you multiply this term by 1/2:

$a_2=\dfrac{1}{2}a_1=\dfrac{1}{2}\cdot 1=\dfrac{1}{2}$

And, to find the next term, you multiply this term by 1/2:

$a_3=\dfrac{1}{2}a_2=\dfrac{1}{2}\cdot\dfrac{1}{2}=\dfrac{1}{4}$

Then the first three terms are ...

1, 1/2, 1/4

Spain = 140
Italy = 40
France = 60
U.S.A = 120
total = 18,000,000

Spain : 140/360 = 39%.....0.39(18,000,000) = 7,020,000
Italy : 40/360 = 11%....0.11(18,000,000) = 1,980,000
France : 60/360 = 17%....0.17(18,000,000) = 3,060,000
U.S.A : 120/360 = 33%...0.33(18,000,000) = 5,940,000
