Answer:

x = 1/2

Step-by-step explanation:

<em>Simplify the sides of the equation...</em>

<em>10x + 3 = 4x + 6</em>

<em>Subtract 3 from both sides...</em>

<em>10x = 4x + 3</em>

<em>Subtract 4x from both sides...</em>

<em>6x = 3</em>

<em>Divide by 6</em>

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

Answer:

x= 1/2

Step-by-step explanation:

First, combine the x terms on both sides of this equation:

10x + 3 = 4x + 6

Next, combine like terms, obtaining 6x = 3.

Dividing both sides of this equation by 6, we get x = 1/2

The function f has first derivative given by f'(x)=(x)^1/2/1+x+x^3. What is the x-coordinate of the inflection point of the grap
Anestetic [448]
Inflection at f'(x) = 0 
<span>
x^1/2 / (1 + x + x^3) = 0 </span>

<span>The x coordinate is x = 0 </span>
<span>
or "C" from your choices there. </span>

<span>The simplest way is to notice that this happens when x = 0. The reason is you got: </span>
<span>
x^1/2 / (some expression) </span>
<span>
at x = 0 the numerator is 0 so unless the denominator is also 0 the result is 0. </span>
<span>
The denominator for x = 0 is 1 so you get </span>
<span>
0/1 = 0.

Hey there!!

80% = 80/100 = 0.8

80% of 'n' = 72

0.8n=72

n = 72/0.8

n = 90

Hence, the number is 80!

Hope it helps!
