Answer:

The Answer is x=6

Step-by-step explanation:

Pull out like factors :

  3x - 18  =   3 • (x - 6)

Equation at the end of step

1

:

STEP

2

:

Equations which are never true:

2.1      Solve :    3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2      Solve  :    x-6 = 0

Add  6  to both sides of the equation :

                     x = 6

One solution was found :

x = 6

Hope this helps:)

Answer:

x=6

Step-by-step explanation:

<em>x</em><em>+</em><em>2</em><em>x</em><em>-</em><em>4</em><em>=</em><em>1</em><em>4</em>

<em>FIRST</em><em> </em><em>STEP</em><em>;</em>

<em>GROUP</em><em> </em><em>LIKE</em><em> </em><em>TERMS</em>

<em>x</em><em>+</em><em>2</em><em>x</em><em>-</em><em>4</em><em>=</em><em>1</em><em>4</em>

<em>x</em><em>+</em><em>2</em><em>x</em><em>=</em><em>1</em><em>4</em><em>+</em><em>4</em>

<em>Then</em><em> </em><em>you</em><em> </em><em>add</em>

<em>3</em><em>x</em><em>=</em><em>1</em><em>8</em>

<em>Then</em><em> </em><em>you</em><em> </em><em>divide </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>3</em><em> </em><em>to </em><em>find</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of </em><em>x</em>

<em>1</em><em>8</em><em> </em><em>can</em><em> </em><em>be</em><em> </em><em>divi</em><em>ded</em><em> </em><em>by</em><em> </em><em>3</em><em>,</em><em> </em><em>6</em><em> </em><em>times</em><em> </em><em>so</em><em> </em><em>it</em><em> </em><em>leaves</em><em> </em><em>our</em><em> </em><em>answer</em><em> </em><em>as</em><em>;</em>

<em>x</em><em>=</em><em>6</em>

How to do step by step?
lorasvet [3.4K]
We know the opposite side (10) and the adjacent side (7), so we can use tangent to find angle B.  Since tan = opposite side/adjacent side, we can set up this equation: tan(B) = 10/7.  We can get B on its own by making the equation this: B = tan^{-1} (10/7)

Now, we plug this into our calculator to get:

B = 55°, so angle B is 55°.

Let me know if you need any more help!

If the function m not-equals 0 has an inverse function, which statement must be true? B not-equals 0
Kipish [7]

Answer:

Option a: m ≠ 0

Step-by-step explanation:

After a small online search, I've found that the complete question is:

If the function f(x) = m*x + b has an inverse function, which statement must be true?

a) m ≠ 0

b) m = 0

c) b ≠ 0

d) b = 0

Ok, if g(x) is an inverse of the function f(x), then:

g( f(x)) = x

f( g(x)) = x

Let's assume that f(x) = m*x + b  has an inverse, and this inverse function is g(x).

Because f(x) is linear, g(x) is also linear, then:

g(x) = n*x + c

Let's find the values of A and B.

We know that:

f( g(x)) = x =  m*(n*x + c) + b

then

x = m*n*x + m*c + b

Then we must have:

m*n = 1

(m*c + b)  = 0

From the first equation m*n = 1

We get:

n = 1/m

The slope of the inverse function is one over the slope of the original function.

Because m is on the denominator, m can not be equal to zero (because a division by zero is not defined)

Then the correct option is the option a, m ≠ 0.
