What is the solution to this equation? log_7 (5 + 11x) = 2

11111nata11111 [884]

Answer:

x = 4

Step-by-step explanation:

Using the rule of logarithms

$log_{b}$ x = n , then x = $b^{n}$

Given

$log_{7}$ (5 + 11x) = 2 , then

5 + 11x = 7² = 49 ( subtract 5 from both sides )

11x = 44 ( divide both sides by 11 )

x = 4

Which is not a step in finding the scale factor of dilation

mariarad [96]

1)To find a Scale factor of Dilation, about the origin

We have

Pre-mage Image

(x, y) k(x,y)

For example

Pre-image Image

(2,4) 2(2,4) = (4,8)

2)When it's not about the origin then we have to count from the Projection Point

Having said this, ex

Which is not a step

We can divide the x value of the image over the pre-image, not the way around.

In the example, I've given if we divide the pre-image over the image value we would have found a scale factor of 1/2. In the example, The scale factor was the inverse: 2
