GDP was a linear function of time (year) during the period of 1985-99.
The slope is positive.
Equation is: GDP(y)=(y-1985)*0.032*577+577=577*[(y-1985)*0.032+1] check: if y=1985, then GDP=577 .
So, we need to solve for "y" this equation: GDP=4000=577*[(y-1985)*0.032+1]then, y=[4000/577-1]/0.032+1985 =  2170.4 
we solveGDP=2200=577*[(y-1985)*0.032+1]  [4 is replaced by 2.2] y=[2200/577-1]/0.032+1985=2072.9  [almost 2073]

You have quarters and dimes that total $2.80. Your friend says it is possible that the number of quarters is 8 more than the num
AnnyKZ [126]

Answer:

Step-by-step explanation:

d = number of dimes

2.80 = 0.1d + 0.25 (d + 8 )

2.80 = 0.1d + 0.25d + 2            Combine like terms

2.80 = 0.35d + 2                       Subtract 2 from both sides

0.80 = 0.35d                             Divide both sides by 0.35

d ≈ 2.29

No, it's not possible to have more quarters than dimes when the total is $2.80 because it's not possible to have part of a dime.

Fred has a bag of coin with only nickels and quarters. He got $20 by
Sedbober [7]

Answer:

75 quarters 25 nickels

Step-by-step explanation:

q=quarters n=nickels

q+n=100   n=100-q

0.25q +0.05(100-q)=20

From now I will multiply  by 100 to avoid decimals

25q + 5(100-q)=2000

20q=1500

q=75       n=25

75*0.25= 18.75

25*0.05=1.25

18.75+1.25=20

svetlana [45]

Answer:

y=-2x+5

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(5-0)/(0-2.5)

m=5/-2.5

m=-2

y-y1=m(x-x1)

y-0=-2(x-2.5)

y=-2(x-2.5)

y=-2x+5
