Answer:

y=-x/3+2

Step-by-step explanation:

If you graph out 3x-y-7=0, you will get a line that goes through the points (0, -7), and about (2.3, 0). If you graph out y=x/3+2, you have to make sure that this line forms a 90 degree angle on the previous line, thus making this line perpendicular to the previous line.

JulijaS [17]

Answer:

42.06 ft²

Step-by-step explanation:

          2 sides = 2(2.7 ft × 3.2 ft) = 2 × 8.64 ft² =   17.28 ft²

 Front + back =  2(2.1 ft × 3.2 ft) = 2 × 6.72 ft² =   13.44 ft²

Top + bottom =   2(2.1 ft × 2.7 ft) = 2 × 5.67 ft² =   <u>11.34 ft² </u>

                                                         Total area = 42.06 ft²

Since 1972 the US. inflation rate has averaged 4.8 % per year . Use the approximate doubling time formula to estimate the doubli
Artemon [7]

Answer:

14  3/4 years

Step-by-step explanation:

Let's assume compound inflation.  The appropriate formula for that is:

A = P(1 + r)^t.

If we represent current prices by P, then double that would be 2P:

2P = P(1 + 0.048)^t    Find t, the time required for prices to double.

Then:

2   =  1.048^t

Taking the natural log of both sides, we get:

ln 2 = t·ln 1.048, so that:

t = (ln 2) / (ln 1.048)   =   14.78

At 4.8 inflation, with annual compounding, prices will double in approx. 14 3/4 years.
