A: the initial price of the used car
b: decreasing percent (decay ratio in decimal)
x: number of years
y: the value of car at a given year
$y=a(1-b)^x\\~\\~\\y=15250(1-0.075)^x\\~\\~\\y=15250(0.925)^x$

That is for part 1

Part 2:
after 8 years
plug in x=8 into the equation that we've just formed
<span> $y=15250(0.925)^8$

and do you math...

</span>

I hope that helps!

I am with you if you faced any difficulties!

Car value at the time of purchase $15, 250 (2012)
Rate of depreciation 7.5%
1) y = 15250 ( 1- 0.075)^x
y = 15250 (0.925)^x (x tis the number of years that passed since purchase)

2) y = 15250 * ( 0.925)^8 = 8173.42

FWML is a parallelogram. Find the values of x and y. Solve for the value of z, if z=x−y

Dima020 [189]

Answer:

$x=5$

$y=8$

$z=-3$

Step-by-step explanation:

We have been given a parallelogram. We are asked to solve for the values of x and y.

We know that opposite sides of parallelogram are equal, so we can set equation as:

$3x-3=x+7$

$3x-x-3=x-x+7$

$2x-3=7$

$2x-3+3=7+3$

$2x=10$

$\frac{2x}{2}=\frac{10}{2}$

$x=5$

Similarly, we will solve for y.

$2y-6=y+2$

$2y-y-6=y-y+2$

$y-6=2$

$y-6+6=2+6$

$y=8$

To solve for z, we will subtract y from x as:

$z=x-y\\z=5-8\\z=-3$

Therefore, the value of z is negative 3.

What must be subtracted from 4x4 - 2x3 -6x2 + x - 5 so that the result is exactly divisible by 2x2 + 3x - 2? PLS ANSWER. I WILL

Answer:

Step-by-step explanation:

To solve this we should use the Euclidean division :

Our polynomial function is 16-2x³-6x²+x+9=-2x³-6x²+x+9
we should divided by : 4+3x-2=3x+2 and see the rest

Here is a picture with the operation

the rest is 47/9 so the number I SHOULD SUBSTACT IS 47/9

Rectangle ABCD with coordinates A(1,1), B(4,1), C(4,2) and D(1,2) dilates with respect to the origin to give rectangle A’B’C’D’.

Delvig [45]

Answer: Option C.

Step-by-step explanation:

You need to find the distance AB with the formula for calculate the distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Then, substituting the coordinates of the points A(1,1) and B(4,1), you get:

$AB=\sqrt{(4-1)^2+(1-1)^2}=3$

You know that A'B'=6, then the scale factor of dilation can be calculated with:

$k=\frac{A'B'}{AB}$

Substituting values, you get:

$k=\frac{6}{3}\\\\k=2$

This matches with the option C.

Which of the following is a radical equation? x + StartRoot 5 EndRoot = 12 x squared = 16 3 + x StartRoot 7 EndRoot = 13 7 Start

d1i1m1o1n [39]

Answer:

x = 3

Step-by-step explanation:

$(8x-8)^{3/2}=64$

Multiply both sides by the exponent 2/3.

$8x - 8 = 64^{2/3}$

Solve for the exponent.

$8x-8=16$

Add 8 to both sides.

$8x = 16+8$

$8x=24$

Divide 8 into both sides.

$x=24/8$

$x=3$
