A motorcycle cost $12,000 when it was purchased. The value of a motorcycle decreases by 6% each year. Find the rate of decay eac

dalvyx [7]

the rate of decay each month can calculated using the following formula:

6%/year × 1 year/(12 months) = 0.5%/month
0.06 x 1/12 = 0.005/month
So the 0.5% is the right answer.
I hope it helped.

Solve the following system of linear equations by graphing.

Oksanka [162]

Answer:

See Explanation

Step-by-step explanation:

For $y=-\frac{1}{2}+3$ : (0,3) (2,2)

The equation is in slope intercept form. y=mx+b

The y intercept is 3.

The slope is 1/2.

Moving one unit down and 2 units to the right, we get (2,2)

For $y=2x-2$ : (0,-2) (1,0)

The y intercept is -2.

The slope is 2.

Moving 2 units up and 1 unit to the right, we get (1,0)

Which two values of x are roots of the polynomial below? 3x2-3x+1

QveST [7]

Answer:

The roots are

$x=\frac{1}{6} [3+ i\sqrt{3}]$

$x=\frac{1}{6} [3- i\sqrt{3}]$

Step-by-step explanation:

we have

$3x^2-3x+1$

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$3x^2-3x+1=0$

$a=3\\b=-3\\c=1$

substitute in the formula

$x=\frac{-(-3)\pm\sqrt{-3^{2}-4(3)(1)}} {2(3)}$

$x=\frac{3\pm\sqrt{-3}} {6}$

Remember that

$i=\sqrt{-1}$

$x=\frac{1}{6} [3\pm i\sqrt{3}]$

The roots are

$x=\frac{1}{6} [3+ i\sqrt{3}]$

$x=\frac{1}{6} [3- i\sqrt{3}]$

Brett has 5/6 of his monthly income left to spend. He has budgeted 1/8 of his income for a new video game and 1/3 of his income

Olenka [21]

Answer:

The only true statement is c. Brett will have 3/8 of his income left after buying the video game and putting money in savings.

Step-by-step explanation:

In order to find this, start by subtracting the fractions of what he'll be spending from the total he has to start.

5/6 - 1/8 - 1/3

Now give them all common denominators

20/24 - 3/24 - 8/24

9/24

Now simplify the fraction.

3/8
