Answer:

You multiply 5 by 1/5 to get 1. So with 2x, you multiply by 1/(2x) to get 1. That's about all you know, since we only know that x is positive.

Step-by-step explanation:

Hope it helps

Answer:

$\frac{25}{10x-1}$

Step-by-step explanation:

The multiplicative inverse of "a" is " $\frac{1}{a}$ "

a × $\frac{1}{a}$ = 1

~~~~~~~~~~~

$\frac{1}{5}$ ( 2x - $\frac{1}{5}$ ) = $\frac{2}{5}$ x - $\frac{1}{25}$

1 ÷ ( $\frac{2}{5}$ x - $\frac{1}{25}$ ) = 1 ÷ ( $\frac{10x}{25}$ - $\frac{1}{25}$ ) = 1 ÷ ( $\frac{10x - 1}{25}$ ) = $\frac{25}{10x-1}$

The multiplicative inverse of the product is $\frac{25}{10x-1}$

What is the lateral area of the cone to the nearest whole number? The figure is not drawn to scale. Helppp which one is it

dezoksy [38]

It would be 49,009 because LA of a cone is height (50) times the radius (120) and that equals about 49,009.

Can someone please help

Answer:

x ≥ 1 (how to graph is listed below)

Step-by-step explanation:

To find where we need to plot the line, we first need to solve the inequality for x:

-2x - 3 ≤ -5

(Add three to both sides)

-2x ≤ -2

(Divide both sides by -2, but we can't forget that whenever we multiple or divide by a negative number, the sign flips!)

x ≥ 1

To graph this on the number line, you would put a dot on the 1 and fill it in completely (you fill in the dot for a "___ and equal to" sign. ex. ≥, ≤)

Then you would make an arrow from the dot to the right on the number line (this is because x must be greater than or equal to 1, so it must be facing in that direction)
