Answer:

$\quad y=-\frac{2\left(-2x+9\right)}{3}$

Step-by-step explanation:

1. Subtract 8x from both sides:

8x-6y-8x=36-8x

2. Simplify:

-6y=36-8x

3. Divide both sides by -6

$\frac{-6y}{-6}=\frac{36}{-6}-\frac{8x}{-6}$

4. Simplify to get answer

MAVERICK [17]

Answer:

$\displaystyle \frac{5x}{8y^{4}}\sqrt{x}$

Step-by-step explanation:

<u>Simplfy in Algebra </u>

We have the following expression

$\displaystyle E=\sqrt{\frac{25x^9y^3}{64x^6y^{11}}}$

Simplifying like factors in the denominator and numerator

$\displaystyle E=\sqrt{\frac{25x^3}{64y^{8}}}$

All the factors are perfect squares except $x^3$ , thus we rewrite:

$\displaystyle E=\sqrt{\frac{25xx^2}{64y^{8}}}$

Taking the square root of all the perfect square factors:

$\boxed{\displaystyle E=\frac{5x}{8y^{4}}\sqrt{x}}$

Justin plantes tomatoes in 1/3 of his 6 by 6 garden Gina planted tomatoes in her 1/3 of her 8 by 6 garden how many square feet o

frutty [35]

Answer:

12 ft^2

Step-by-step explanation:

Justin's garden is 6 ft by 6 ft.

The area of a square is the square of the side.

A = s^2 = (6 ft^2) = 36 ft^2

1/3 of the garden has an area 1/3 of 36 ft^2.

1/3 * 36 ft^2 = 36/3 ft^2 = 12 ft^2

Answer: 12 ft^2

dilation the center of dilution is the origin b (2,3) and B(-4,-6) what is the scale factors of this dilation that transformed a

Ann [662]

Given:

Consider the two points are B(2,3) and B'(-4,-6).

Center of dilation is the origin.

To find:

The scale factors of this dilation that transformed B into B'.

Solution:

If a figure dilatated by scale factor k and center of dilation is the origin, then

$(x,y)\to (kx,ky)$

It means, the point after dilation is

$(x',y')=(kx,ky)$

where, k is the scale factor.

$k=\dfrac{x'}{x}$

x-coordinate of image is -4 and x-coordinate of original point is 2.

$k=\dfrac{-4}{2}$

$k=-2$

Therefore, the scale factor is -2. It means, the point and image lie on the opposite sides of center of dilation.
