Step-by-step explanation:

The car will have some value. It will not decrease to nothing

We take 1/3 away from the value each year

This means we keep 2/3 of the value

Year 0 value 18000

Year 1 value 18000 *2/3

Year 2 value 18000 * 2/3 * 2/3

Year 3 value 18000 * 2/3 * 2/3 * 2/3

Year 6 value 18000 * 2/3 * 2/3 * 2/3* 2/3 * 2/3 * 2/3

value 18000 * 2/3 ^6

Year t value = 18000 * 2/3 ^ t

v = 18000 * 2/3 ^t

How much would it be after 10 years? Why?

yawa3891 [41]

$15 interest to 2 years simplified would be $7.50 interest per year. $7.50 multiplied by 10 years would be $75 interest.

Solve the system of equations given below.

eduard

Answer:

The system of this equation is ( -1, 10) which is Option A.

Step-by-step explanation:

Solve for y in the first equation.

$y = - 5x + 5 \\ - 2y = - x - 21$

Replace all occurrences of yy with -5x+5 in each equation.

$10x - 10 = - x - 21 \\ y = - 5x + 5$

Solve for x in the first equation.

$x = - 1 \\ y = - 5x + 5$

Replace all occurrences of x with -1 in each equation.

$y = 10 \\ x = - 1$

The solution to the system is the complete set of ordered pairs that are valid solutions.

(−1, 10)

Hence, the system of this equation is (-1, 10). 

Option A.

A Square has the vertices at (-2,6) (6,1) (1,-7) (-7,-2). At what point do the diagonals of the square intercect

DerKrebs [107]

Answer: At point ( $-\frac{1}{2},-\frac{1}{2}$ )

Step-by-step explanation: Diagonal is a line uniting two opposite points. In a square, the diagonals intersect in a 90° and bisect each other, i.e., divides each diagonal into two segments of the same length.

In other words, the diagonals of a square meet at their midpoint, which is found as the following:

(x,y) = $(\frac{x_{1}+x_{2}}{2} ,\frac{y_{1}+y_{2}}{2})$

The opposite vertices of the given square are (-2,6) and (1,-7).

So, the intersection is

(x,y) = $(\frac{-2+1}{2} ,\frac{6-7}{2})$

(x,y) = $(-\frac{1}{2},-\frac{1}{2} )$

The diagonals of square with vertices (-2,6)(6,1)(1,-7)(-7,-2) intersect at point $(-\frac{1}{2},-\frac{1}{2} )$ .
