Answer:

n=3

Step-by-step explanation:

-4n-40=-2(7n+5)

Distribute the -2

-4n -40 = -14n -10

Add 14n to each side

-4n+14n -40 = -14n +14n-10

10n -40 = -10

Add 40 to each side

10n -40+40 = -10+40

10n = 30

Divide each side by 10

10n/10=30/10

n =3

A square has one side that is 19 cm long. What is the perimeter of the square?

Komok [63]

Since a square has 4 equal sides, just do 19 + 19 + 19 + 19 which is 76. Or, 19 x 4, even though you add with permieter, it'll still work on a square.

Hope I helped!

If f(x) = -2x + 4, then f^-1(x) =

Nadusha1986 [10]

Answer:

$f^{-1}(x) = -\frac{x}{2} +2$

Step-by-step explanation:

Consider the real number y such that f ⁻¹(x) = y

$f^{-1}\left( x\right) =y\Longleftrightarrow f\left( y\right) =x$

We need to find y in order to determine the expression of f ⁻¹(x)

f(y) = x ⇔ -2y + 4 = x

⇔ 4 - x = 2y

⇔ y = (4 - x)/2

$\Longleftrightarrow y=-\frac{x}{2} +2$
