For this equation, give two values for x for which the value of y is negative. <br> (y= -2x-5)

Vinil7 [7]

Answer:

Value 1: -2

Value 2: 10

Step-by-step explanation:

To make y negative, -2 ≤ x ≤ ∞

In other words, x must be equal to or greater than -2 for the value of y to be negative.

Value 1: -2

y = -2(-2) - 5

y = 4 - 5

y = -1

Value 2: 10

y = -2(10) - 5

y = -20 - 5

y = -25

What is the volume of a sphere with a radius of 12 units?

$\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}$

$\sf{Formula \ for \ Volume \ of \ a \ sphere \ :$ $\bigstar\boxed{\bold{V=\displaystyle\frac{4}{3} \pi r^3}}$

Where

$\tt{V=Volume}\\\tt{\pi =pi}\\\tt{r=radius}$

Provided Information:-

$\tt{r=12\:units}$

Plug in:-

$\bold{V=\displaystyle\frac{4}{3} \pi (12)^3}$

$\bold{V=\displaystyle\frac{4}{3} \pi (1,728)}$

On further simplification,

$\dashrightarrow\boxed{\boxed{\underline{\bold{V=2304\pi\:m^3}}}}\dashleftarrow$
