You can expand this using the binomial theorem 

= 1/256 + 4C1 (1/4)^3 y + 4C2 (1/4)^2 y^2 + 4C3 (1/4) y^3 +  y^4

= 1/256 + 1/16 y +  3/8 y^2 +  y^3 + y^4

I need help on this I am just going to use the picture
Radda [10]

Answer:

D

Step-by-step explanation:

let y = f(x), that is

y = \frac{2x-3}{5}

Rearrange making x the subject

Multiply both sides by 5

5y = 2x - 3 ( add 3 to both sides )

5y + 3 = 2x (divide both sides by 2 ) , then

x = \frac{5y+3}{2}

Change y back into term of x, hence

f^{-1}(x) = \frac{5x+3}{2} → D

Find the slope of the line that would pass
Leno4ka [110]

Answer:

10

Step-by-step explanation:

Here we go!

Slope Formula:

\frac{ {y}^{2} -  {y}^{1}  }{ {x}^{2} -  {x}^{1} }

What we know: (-4, -52) and (-1, -22)

Plug in the numbers!

\frac{ - 52 - ( - 22)}{ - 4 - ( - 1)}

Fix it!

\frac{ - 52 + 22}{ - 4 + 1}

Add

\frac{ - 30}{ - 3}

Divide

(negative divided by a negative is a positive!!)

Slope is 10

Hope this helps!
