The value of a car dropped from $23,600 to $21,900 over the last year. Determine the actual and relative change in this situation.


Actual Change: ? This car's value decreased by $

last year.

Round your answer to the nearest dollar.


Relative Change: ? This car's value decreased by

% last year.

Round your answer to the nearest tenth of a percent.

Answers

Answer:

The actual change in the car's value is $[tex]1700[/tex] and the relative change is [tex]7.20[/tex]%.

Step-by-step explanation:

It is given that the value of a car is dropped from $[tex]23600[/tex] to $[tex]21900[/tex].

So, the change in the value is the drop in the value of car, which is, [tex]23600-21900=1700[/tex].

So, the actual change in this car's value is $[tex]1700[/tex].

The relative change can be given by the expression,

[tex]\dfrac{\:\rm{Actual Change}}{\:\rm{Original Value}}\times100[/tex]

Substituting values, the relative change can be given by,

[tex]\begin{aligned}\dfrac{1700}{23600} \times 100&=\dfrac{1700}{236}\\&=7.20\end{aligned}[/tex]

I have to solve this absolute value equation: |4x-3| = |x+5|

Answer:

  x = {-2/5, 2 2/3}

Step-by-step explanation:

There are several ways you can solve this. Maybe the simplest is to take advantage of the relation ...

  [tex]\sqrt{x^2}=|x|[/tex]

Squaring the absolute value expression on both sides gives ...

  (4x -3)^2 = (x +5)^2

  15x^2 -34x -16 = 0 . . . . rewrite to standard form

  (5x +2)(3x -8) = 0 . . . . . factor

  x = -2/5, +8/3

__

Check

To determine if one of these solutions is extraneous, we can try them both in the original equation. We find they both satisfy the equation, so neither found solution is extraneous.

For x=-2/5, |4(-2/5)-3| = |-2/5 +5|  ⇒  |-4 3/5| = |4 3/5| . . . . true

For x = 8/3, |4(8/3) -3| = |8/3 +5|  ⇒  |(32 -9)/3| = |(8 +15)/3| . . . . true

_____

Additional comment

Often, we solve absolute value equations using piecewise functions:

  |4x -3| = {4x -3, for x ≥ 3/4; -4x +3, for x < 3/4}

  |x +5| = {x +5, for x ≥ -5; -x -5, for x < -5}

Now, we have three regions in which to look for solutions: (-∞, -5], [-5, 3/4], [3/4, ∞).

In the region (-∞, -5], the equation is ...

  -4x +3 = -x -5   ⇒   x = 8/3 . . . . . no solution in the region

In the region [-5, 3/4], the equation is ...

  -4x +3 = x +5   ⇒   x = -2/5 . . . . . a solution in the region

In the region [3/4, ∞), the equation is ...

  4x +3 = x +5   ⇒   x = 8/3 . . . . . . a solution in the region

Note that this last equation is identical to the equation for the region (-∞, -5] with both sides multiplied by -1.

Effectively, we have found the two solutions to ±(4x -3) = (x +5). The trick is to figure whether either of those solutions lies in the region for which the respective equation is defined.

. Pencils are sold in packages of 10, and erasers are sold in packages of 6. What is the least number of pencils and erasers you can buy so that there is one pencil for each eraser with none left over?​

Answers

Answer:

3 packs of pencils

5 packs of erasers

Step-by-step explanation:

To solve this problem, find the least common multiple. The least common multiple is the smallest number that both terms are a factor of. In this case, that number is 30. Both 10 and 6 are a factor of 30. So, the answer is the other factor needed to get 30 through multiplication. 10's other factor is 3 and 6's other factor is 5. Therefore, the answers are 3 and 5 respectively.

Use the midpoint formula to find the midpoint of the segment whose endpoints are
(3,-2) and (-5, 8).
O (4, 5)
.0 (-1, )
O (1, -3)
0 (-1, 3)

Answers

Answer:

(-1;3)

(3 - 5)/2 = -1

(-2 + 8)/2 =3

Midpoint of segment (3, -2) and (-5, 8) is (-1, 3).

The midpoint formula allows us to find the point that lies exactly halfway between two given points on a line segment. For two points represented as (x₁, y₁) and (x₂, y₂), the midpoint ([tex]x_m[/tex], [tex]y_m[/tex]) is calculated using the formula:

[tex]x_m[/tex] = (x₁ + x₂) / 2

[tex]y_m[/tex] = (y₁ + y₂) / 2

Now, let's apply this formula to find the midpoint of the segment with endpoints (3, -2) and (-5, 8):

x₁ = 3, y₁ = -2

x₂ = -5, y₂ = 8

[tex]x_m[/tex] = (3 + (-5)) / 2 = (-2) / 2 = -1

[tex]y_m[/tex] = (-2 + 8) / 2 = 6 / 2 = 3

So, the midpoint of the segment is (-1, 3).

In this explanation, we used the midpoint formula, represented by the subscript "m," to find the midpoint ([tex]x_m[/tex], [tex]y_m[/tex]) of the segment with endpoints (x₁, y₁) and (x₂, y₂). By substituting the given coordinates into the formula, we computed the x-coordinate and y-coordinate separately. The midpoint gives the exact center of the segment, dividing it into two equal parts. In this case, the midpoint lies at (-1, 3), which is indeed the point that is equidistant from both (3, -2) and (-5, 8) on the line segment.
