Answer:

81-25k²

Step-by-step explanation:

We need to write the expression for "The quantity 81 minus 5k, squared".

Square of any number x is given by x².

Square of 5k is given by : (5k)²= 5²×k²=25k²

Now subtract 25k² from 81.

It means we get : 81-25k². It is required expression.

Answer this please!​
Troyanec [42]

f(x) = 4x + 3

That's one-to-one, a linear function that will give a different f(x) for each different x.

For the inverse let's swap x and y and solve for y

x = 4y + 3

x - 3 = 4y

y = (x- 3)/4

That's the inverse,

Answer:  (x- 3)/4, second choice

The domain and range of the inverse is all real numbers.  It's two lines; I'll leave the graphing to you.

OlgaM077 [116]
\bf \textit{volume of a rectangular prism}\\\\
V=lwh\qquad 
\begin{cases}
l=x+2\\
w=3\\
V=3x^2 + 18x+ 24
\end{cases}\implies \cfrac{V}{lw}=h
\\\\\\
\cfrac{3x^2 + 18x+ 24}{3(x+2)}=h\implies \cfrac{\underline{3}(x^2 + 6x+ 8)}{\underline{3}(x+2)}=h
\\\\\\
\cfrac{(x+4)\underline{(x+2)}}{\underline{(x+2)}}=h\implies x+4=h

Makovka662 [10]

Answer:

35

Step-by-step explanation:

Here is the full steps:

Distribute

-7(x+10)=7(5-x)

-7x-70=7(5-x)

Distribute

-7x-70 = 35-7x            → Answer for the attachment "35"

Add 70  to both sides of the equation

-7x-70+70=-7x+35+70

Simplify

-7x=-7x+105

Add 7x  to both sides of the equation

-7x+7x=-7x+105+7x

0 = 105
