Answer:

$\boxed{\bold{x>3}}$

Step By Step Explanation:

Subtract 2 From Both Sides

$\bold{7x+2-2$

Simplify

$\bold{7x$

Subtract 9x From Both Sides

$\bold{7x-9x$

Simplify

$\bold{-2x$

Multiply Both Sides By -1 (Reverse Inequality)

$\bold{\left(-2x\right)\left(-1\right)>\left(-6\right)\left(-1\right)}$

Simplify

$\bold{2x>6}$

Divide Both Sides By 2

$\bold{\frac{2x}{2}>\frac{6}{2}}$

Simplify

$\bold{x>3}$

the variance
the population mean

The absolute difference between either limit and the mean is an example of THE VARIANCE.

Variance is defined as the average of the squared differences from the Mean.

Mr. Henderson’s annual premium of $4,668 is covered entirely by his employer along with 25% of the $9,264 premium for his wife a

IRINA_888 [86]

The fully covered premium amounts to $4,668. Next, we calculate the partially covered premium using: 25% * 9,264 = 2,316 Now, the total annual premium paid by Mr. Henderson's employer is equivalent to the sum of the completely covered premium and partially covered premium. This is: 4,668 + 2,316 = $6,984 of the Henderson family's annual premium is covered by Mr. Henderson's employer

The volume of a cone is 3rx? cubic units and its height is x units. Which expression represents the radius of the cone's base, i

Marianna [84]

Answer:

It is given that the volume of a cone = $3\pi x^3$ cubic units

Volume of cone with radius 'r' and height 'h' = $\frac{1}{3}\pi r^2h$

Equating the given volumes, we get

$3\pi x^3=\frac{1}{3}\pi r^2h$

$r^2h=3$ × $3x^3$

$r^2h=9 x^3$

It is given that the height is 'x' units.

Therefore, $r^2x=9x^3$

$r^2=9x^2$

Therefore, $r=3 x$

So, the expression ' $3 x$ ' represents the radius of the cone's base in units.
