Answer:

  d.  $137,604

Step-by-step explanation:

The amortization formula is good for this. It tells you the principal P that must be invested to support payments of A each year for t years when the interest rate is r:

  P = A(1 -(1 +r)^-t)/r

  P = $12,000(1 -1.06^-20)/0.06 ≈ $137,639.05

The closest answer choice is $137,604.

The graph shows the solution for which inequalities?
Helen [10]

Answer:

Inequalities are,

y ≥ 4x + 2

y ≥ 2

Step-by-step explanation:

Solid yellow line of the graph attached passes through two points (0, -2) and (1, 2).

Let the equation of this line is,

y = mx + b

Slope of the line = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

                      m = \frac{2+2}{1-0}

                      m = 4

Y-intercept 'b' = -2

Equation of the line will be,

y = 4x - 2

Since shaded area is on the left side of this solid line so the inequality representing this region will be,

y ≥ 4x - 2

Another line is a solid blue line parallel to the x-axis.

Shaded region (blue) above the line will be represented by,

y ≥ 2

Therefore, the common shaded area of these inequalities will be the solution of the given inequalities.

I need help on this question anything help
elixir [45]

Answer:

y = -3x - 1

Step-by-step explanation:

Look at your line. It's a downward trend which means your slope is negative

slope is the m in y = mx+b

Your b is your y intercept or where the graph touches the y = 0 vertical line.

It cross at -1 value

Your slope value is determined by rise/run so in the case it goes down 3 values and across 1 value so its 3/1 but its negative so its -3/1

Find the inequality represented by the graph someone help please
Alecsey [184]
U have a solid line...meaning there is an equal sign in the problem
u have a y int of -1 (the y int is where ur line crosses the y axis)
u have a slope of : 1
it is shaded below the line...so it is less then

so ur inequality is : y < = x - 1 <==
