X= 5
Simplify the equation

x=4=36-12x + X^2
Move the expression to the left
x-4-36+12x-x^2=0
Collect like terms
Calculate
13x-40-x^2=0
Reorder the terms

-x^2+13x-40 = 0
Change the signs
-x^2+13x+40=0
Rewrite the expression
x^2-5x-8×+40=0
Factor the expressions
x•( x-5)-8(x-5 )=0
Factor the expression
(x-5)•(x-8)=0
Separate into possible cases
x-5=0
x-8=0
Solve the equations
x=5
x=8
Check the solutions
6=6
10=6
x=5 is a solution
x=8 is not a solution

<h2><u>Radical Equations</u></h2>

<h3>Solve algebraically for all x values</h3>

√(x - 4) + x = 6

To solve for x, make sure to remove first the radical sign before simplifying. To remove the radical sign (since it is square root) raise each side of the equation with an exponent of 2.

  • √(x - 4)² + x = 6
  • x - 4 + x = 6

Then start simplifying.

  • x - 4 + x = 6
  • x + x - 4 = 6
  • 2x = 10
  • x = 5

<u>Answer:</u>

  • The value of x is <u>5</u>.

(06.01) What is the value of the expression shown below? 3 over 6 to the power of 2 + 7 × 4 − 5 6 and 1 over 4 6 and 1 over 2 23
never [62]

Answer: 23(1/4)

Step-by-step explanation: this is the answer you can star resolving the equation into the parenthesis

(3/6)² + 7 *4  - 5

if we elevate to the power of 2 the values into the parenthesis, we get the following equation.

(9/36) + 7*4 -5

after this we follow with the values into the parenthesis, if you divide 9 over 36 we get the following result

9/36 = 0.25

then we get the following equation

0.25 +7*4 - 5

after that we can resolve the multiplication getting the following equation

0.25 +28 - 5

then if we resolve the subtraction, we will get this result.

28-5 = 23

then we have 0.25 + 23 this equation is equal to 23.25

if you follow the answer will be one with 23, then we get the possible results, if you divide 1/4=0.25

then we get that the result is

23(1/4)

Line AB passes through points A (-6,6) and B(12,3). If the equation of the line is written in slope-intercept form, y=mx+b, the.
Tomtit [17]

Answer:

You wrote the question wrong...

m is not -16 it is -1/6 (that is a big difference)

y=mx+b

y=-1/6x+b

3 = -1/6(12) + b

3 = -2 + b

b=5

Analyze the key features of the graph f(x) = 1/x+3 -2
tia_tia [17]
<h2>Explanation:</h2><h2></h2>

Here we have the following rational function:

f(x) = \frac{1}{x+3} -2

So the graph of this function is shown in the First Figure below. Let's define another function which is a parent function:

g(x)=\frac{1}{x}

Whose graph is shown in the second figure below. So we can get the graph of f from the graph of g this way:

Step 1. Shift the graph 3 units to the left:

f_{1}(x) = \frac{1}{x+3}

Step 2. Shift the graph 2 units down:

f(x) = \frac{1}{x+3}-2

Finally, the features of the graph of f are:

The graph of this function comes from the parent function g and the transformations are:

  • A shifting 3 units to the left
  • A shifting 2 units down
