What are you solving for? if you are solving for x, then x=(P-12)/(Q-13)

The answer to the question is: Simplifying<span>Qx + 12 = 13x + P Reorder the terms: 12 + xQ = 13x + P Reorder the terms: 12 + xQ = P + 13x Solving 12 + xQ = P + 13x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-13x' to each side of the equation. 12 + -13x + xQ = P + 13x + -13x Combine like terms: 13x + -13x = 0 12 + -13x + xQ = P + 0 12 + -13x + xQ = P Add '-12' to each side of the equation. 12 + -13x + -12 + xQ = -12 + P Reorder the terms: 12 + -12 + -13x + xQ = -12 + P Combine like terms: 12 + -12 = 0 0 + -13x + xQ = -12 + P -13x + xQ = -12 + P Reorder the terms: 12 + -1P + -13x + xQ = -12 + P + 12 + -1P Reorder the terms: 12 + -1P + -13x + xQ = -12 + 12 + P + -1P Combine like terms: -12 + 12 = 0 12 + -1P + -13x + xQ = 0 + P + -1P 12 + -1P + -13x + xQ = P + -1P Combine like terms: P + -1P = 0 12 + -1P + -13x + xQ = 0 The solution to this equation could not be determined. Hope this helps:)

Karen purchased the DVD

9966 [12]

Answer:

Percent markdown = 14%

Step-by-step explanation:

Given:

Original price of DVD player = $175.90

Markdown price of DVD player =$153.77

To find percent markdown.

Amount of mark down $=\textrm{Original price - Markdown price}=\$175.90-\$153.77=\$22.13$

Percent markdown $=\frac{Amount\ of\ markdown}{Markdown\ price}\times100=\frac{22.13}{153.77}\times 100=14.39\%\approx 14\%$

Answer:

t=0.64

Step-by-step explanation:

h = -16t^2 +4t +4

We want h =0 since it is hitting the ground

0 = -16t^2 +4t +4

Using the quadratic formula

a = -16 b = 4 c=4

-b ± sqrt( b^2 -4ac)

----------------------------

2a

-4 ± sqrt( 4^2 -4(-16)4)

----------------------------

2(-16)

-4 ± sqrt( 16+ 256)

----------------------------

-32

-4 ± sqrt( 272)

----------------------------

-4 ± sqrt( 16*17)

----------------------------

-4 ± sqrt( 16) sqrt(17)

-4 ± 4 sqrt(17)

----------------------------

Divide by -4

1 ± sqrt(17)

To the nearest hundredth

t=-0.39

t=0.64

Since time cannot be negative

t=0.64

M is the midpoint of CD. Given the coordinates of one endpoint C(10,-5) and the midpoint M(4, 0), find the coordinates of the ot

mash [69]

Answer:

D(-2, 5).

Step-by-step explanation:

We are given that M is the midpoint of CD and that C = (10, -5) and M = (4, 0).

And we want to determine the coordinates of D.

Recall that the midpoint is given by:

$\displaystyle M = \left(\frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2}\right)$

Let C(10, -5) be (<em>x</em>₁<em>, y</em>₁) and Point D be (<em>x</em>₂<em>, y</em>₂). The midpoint M is (4, 0). Hence:

$\displaystyle (4, 0) = \left(\frac{10+x_2}{2} , \frac{-5+y_2}{2}\right)$

This yields two equations:

$\displaystyle \frac{x_2 + 10}{2} = 4\text{ and } \frac{y_2 - 5}{2} = 0$

Solve for each:

$\displaystyle \begin{aligned}x_2 + 10 &= 8 \\ x_2 &= -2 \end{aligned}$

And:

$\displaystyle \begin{aligned} y_2 -5 &= 0 \\ y_2 &= 5\end{aligned}$

In conclusion, Point<em> </em>D = (-2, 5).
