Answer:

x = 1/ 3

Step-by-step explanation:

to solve this system of equation we have

2/3 x - 4 = -2

collect the like terms or combine the like terms

2/3x = -2 + 4

2 / 3x = 2

the next step is to cross multiply

2 x 1 = 2 (3x)

2 = 6x

divide both sides by the coefficient of x which is 6

2/ 6 = 6x/ 6

x = 2/6

x = 1/ 3

I need help I can’t figure it out

Answer:

$\large\boxed{\dfrac{41p}{70q^4(r-9)^2}}$

Step-by-step explanation:

$\dfrac{2p^4}{5q^5(r-9)^3}\cdot\dfrac{41q(r-9)}{28p^3}\\\\=\dfrac{2\!\!\!\!\diagup^1\cdot41}{5\cdot28\!\!\!\!\!\diagup_{14}}\cdot\dfrac{q\!\!\!\!\diagup}{q^{5\!\!\!\!\diagup^4}}\cdot\dfrac{(r\!\!\!\!\!\!{--}-9)\!\!\!\!\!\!{--}}{(r-9)^{3\!\!\!\!\diagup^2}}\cdot\dfrac{p^{4\!\!\!\!\diagup}}{p^3\!\!\!\!\!\!\diagup}\\\\=\dfrac{41}{70}\cdot\dfrac{1}{q^4}\cdot\dfrac{1}{(r-9)^2}\cdot\dfrac{p}{1}\\\\=\dfrac{41p}{70q^4(r-9)^2}$

Log(x+6)-log(x-3)=1<br><br> I need to show work, please show me how

Illusion [34]

Answer:

x = 4.

Step-by-step explanation:

log(x + 6)- log(x - 3) = 1

Using the law log a - log b = log a/b:

log (x + 6)/ (x - 3) = 1

Removing logs:

(x + 6)/ (x - 3) = 10

x+ 6 = 10x - 30

9x = 36

x = 4 (answer).

Which transformation will map figure Honto figure H? (1 point)

podryga [215]

Answer:

2) Vertical translation of 10 units

Step-by-step explanation:

Given

H and H'

Required

Which maps H to H'

First, we pick the coordinate of any point on H

$H(x,y) = (4,2)$

First, we pick a corresponding coordinate on H'

$H'(x,y) = (4,-8)$

The above coordinates show that H and H' are not a reflection of one another because neither of the x or y coordinates negate one another.

By looking at the coordinates of H and H, we have:

H: $x = 2$ and H': $x = 2$ --- The same x coordinates

H: $y = 2$ and H': $y = -8$ --- Different y coordinates

The difference between the y coordinates is:

$Difference = H(x) - H'(x)$

$Difference = H(2) - H'(2)$

$Difference = 2 - (-8)$

$Difference = 2 +8$

$Difference = 10$

Hence,

<em>2) Vertical translation of 10 units </em> is correct.
