These 2 angles add up to 180 so
(10x-20)+(6x+8)=180
First combine like terms
10x+6x=16x
-20+8=-12
So
16x-12=180
we then want to get x on the side by itself.
So we'll add 12 to both sides, the equation is now
16x=192
Then divide 192/16x=12

so x=12

For f(x) = 2x+1 and g(x) = 3x-7, find (f-g)(x)
marissa [1.9K]

Answer:

(f - g)(x) = -x + 8

General Formulas and Concepts:

  • Order of Operations: BPEMDAS

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 2x + 1

g(x) = 3x - 7

(f - g)(x) = f(x) - g(x)

<u>Step 2: Simplify</u>

  1. Set up:                              (f - g)(x) = (2x + 1) - (3x - 7)
  2. Distribute -1:                     (f - g)(x) = 2x + 1 - 3x + 7
  3. Combine like terms:        (f - g)(x) = -x + 8

Given the function f(x) = -0.5|2x + 2| + 1, for what<br> values of x is f(x) = 6?
Licemer1 [7]

Answer:

<em>No values of x can make f(x)=6</em>

Step-by-step explanation:

Equation with Absolute Value

The absolute value of a number is always positive. That condition must be met when solving equations. Any condition that goes against the rule, must be discarded and not part of the solution.

The function provided in the question is:

f(x) = -0.5|2x + 2| + 1

We need to find the value(s) of x that make:

f(x)=6

It needs to solve the equation:

-0.5|2x + 2| + 1=6

Subtracting 1:

-0.5|2x + 2| =6-1=5

Dividing by -0.5:

|2x + 2| =5/(-0.5)=-10

We reach to this equation to solve:

|2x + 2| =-10

As stated above, the absolute value is always positive, and the equation forces the absolute value to be negative. There is no possible value of x that makes the absolute value negative, thus:

No values of x can make f(x)=6

Juan reads 300 pages 5 days which reading rate is equivalent
katrin [286]
60 pages per day!

It is shown that One is reading 300 pages in five days so we need to find a reading rate which would be the total number of pages one reads over the number of days so the substitute does values by doing 300/5 you would get 60 pages per day
