Answer:

The measure of angle R is 112 degrees

Step-by-step explanation:

Using the given markings, we can see that we have an isosceles triangle

so RT is also 3x-2

Mathematically, the sum of the interior angles of a triangle is 180:

Thus;

9x + 4 + (3x-2) + (3x-2) = 180

9x + 3x +3x + 4-2-2 = 180

15x = 180

x = 180/15

x = 12

Recall; Angle R is 9x + 4

= 9(12) + 4 = 108 + 4 = 112

Combine terms/simolify

-Dominant- [34]

Answer:

$\dfrac{2m -1}{5}$

Step-by-step explanation:

Since we have common denominators inside the parentheses, we can combine the denominators. Then, we get the following expression:

$2\huge\text{(}\dfrac{1}{5} m - \dfrac{2}{5} \huge\text{)} + \dfrac{3}{5}$

$2\huge\text{(}\dfrac{m - 2}{5} \huge\text{)} + \dfrac{3}{5}$

Now, we can multiply the expression inside the parentheses by 2.

$\huge\text{(}\dfrac{2m - 4}{5} \huge\text{)} + \dfrac{3}{5}$

Since the expression inside the parentheses cannot be <u>simplified further</u>, we can open the parentheses and simplify the expression.

$\dfrac{2m - 4}{5} + \dfrac{3}{5}$

We can combine the denominators as the denominators are the same.

$\dfrac{2m - 4 + 3}{5}$

Finally, we can simplify -4 + 3.

$\dfrac{2m -1}{5}$

Therefore, the simplified expression is (2m - 1)/5.

Help pleaseee :) tyy

STatiana [176]

Answer:

The slope is 4

Step-by-step explanation:

First we pick 2 points (x, y):

(0, -2) and (1, 2)

Then, we use the slope (m) formula:

m = (y2 - y1)/(x2 - x1)

Given:

y2 = 2

y1 = -2

x2 = 1

x1 = 0

Work:

m = (y2 - y1)/(x2 - x1)

m = (2 + 2)/(1 - 0)

m = 4/1

m = 4

How to find the rule for the nth term of a geometric sequence with changing common ratio?

ki77a [65]

Hmmm... a geometric sequence MUST have a fixed common ratio. If it is changing, then the sequence you are looking at might not be a geometric sequence at all. We'd need to see an example to be sure.
