Answer:

x=4

Step-by-step explanation:

Well bud, you may have overthought this one a bit too much. It pretty much requires one simple move and then you good. All you gott do is multiply both sides by (-6/5) and that in itself isolates x. This was done because inverses cancel out to 1, and a negative 1 times a negative 1 equals a positive 1. What you get after multiplying both sides by (-6/5) is x=(-10/3)(-6/5) Now all you have to do is multiply and simplify, giving you x=4. You should be gucci now, cuz I got you homie. ;)

Step-by-step explanation:

To transform a function vertically, add 3 to the constant.

$5 + 3 = 8$

So the function is

$3 {x}^{2} + 8$

Graph the function in desmos to show the translation vertically if you want proof

A cube has a surface area of 486 cm2. What is the side length ?

astraxan [27]

A Cube, has all equal sides, namely, the length, width and height
are all equal to each other

so.. notice the picture added here
you have really, 6 squares, stacked up to each other at the edges

so...what is the Area of one of those squares?
well, if the sides are equal, let's say the side is "x" long, then
the Area is $x\cdot x \implies x^2$

well, you have 6 of those squares, thus $\bf \textit{surface area of a cube}=
\begin{cases}
(x\cdot x)+\\
(x\cdot x)+\\
(x\cdot x)+\\
(x\cdot x)+\\
(x\cdot x)+\\
(x\cdot x)\\
 --------------\\
 x^2+x^2+x^2+x^2+x^2\\
6x^2
\end{cases}
\\\\
\textit{we know the Area is }486\ cm^2\qquad thus
\\\\
\textit{surface area}=6x^2\implies 486=6x^2$

solve for "x", to get one side's length
