For the first picture..........

|AB| |BD|
-----=-----
|AC| |DC|

x+8 10
-----=----
2x-5 14

10(2x-5)=14(x+8)

20x-50 = 14x+112

20x-14x = 112+50

6x = 162

x= 162/6

x=27.....

For the second picture.......

AD| |AC|
-----=-----
|DB| |CB|

3 4
--=---
x 7.5

4×X = 3×7.5

x = 22.5/4

x = 5.625....

Write the equation of a line that is parallel to the y axis and passes through the point (-2,5).
dybincka [34]

Answer:

x = -2

Step-by-step explanation:

If it’s parallel to the y-axis, it must be an x value that is straight up and down. The x coordinate here is -2 so the line must be vertical from -2 on the x-axis.

Simplify 14 to the 15th power over 14 to the 5th power . (4 points)
slega [8]

An expression is defined as a set of numbers, variables, and mathematical operations. The given expression when simplified will be equal to 14¹⁰. The correct option is A.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given expression can be simplified as shown below.

14¹⁵ / 14⁵

= 14¹⁵ × (1 / 14⁵)

Using the exponential property 1/aˣ = a⁻ˣ, we can write,

= 14¹⁵ x 14⁻⁵

Using the exponential property aˣ × aᵇ = a⁽ˣ⁺ᵇ⁾, we can write,

= 14⁽¹⁵⁻⁵⁾

= 14¹⁰

Hence, the given expression when simplified will be equal to 14¹⁰.
