Answer:

85/7

Step-by-step explanation:

log2 + log7(x-5) = 2

log(14(x-5)) = 2

14x - 70 = 10²

14x = 170

x = 170/14

x = 85/7 or 12 1/7

What is the value of x to the nearest tenth? 12.0 7.2 4.8 9.2

RUDIKE [14]

Line x is the mid point of both lines
so the triangle becomes base = 19.2/2 = 9.6
hypotenuse = 24/2 = 12

using Pythagorean theorem:

x^2 = 12^2 - 9.6^
x^2 = 144 - 92.16
x^2 = 51.84

x = sqrt(51.84) = 7.2

PLEASE HELP WILL GIVE BRAINLIEST Which of the following scale factors will result in an enlargement? A. k < –1 B. –1 < k &

Sergio [31]

Answer: OPTION A.

Step-by-step explanation:

By definition, a dilation can be an enlargement or a reduction of the shape.

An enlargement is when dilation creates a larger image and a reduction is when dilation creates a smaller image.

When, the scale factor is greater than 1, the image is an enlargement and when the scale factor is between 0 and 1, the image is a reduction.

It is important to know that with a negative scale factor the enlargement will will be inverted and it will also be on the other side of the center of dilation.

Knowing this, we can say that the scale factor that will result in an enlargement is:

$k$
