y= (\frac 1 4 )^x

A reflection about the x axis, about y=0, is the mapping (x',y')=(x,-y) so

y'= -y = - (\frac 1 4)^{x'}

A dilation of 2 is the mapping (x'',y'')=(2x', 2y')

So

x'=x''/2, y'=y''/2

y''/2= - (\frac 1 4)^{x''/2}

y'' =  - 2((\frac 1 4)^{1/2})^{x''}

y''= - 2(\frac 1 2)^{x''}

We can rewrite that without the primes and combine the powers of 2.

y =  - 2^{1-x}

Let's graph these and see if we're close,

Plot y= (1/4)^x, y= - (1/4)^{x}, y = - 2^{1-x}

18 divide by 2 * 3/5-2 simplify show all work
liraira [26]

Answer:

9

Step-by-step explanation:

I would guess it looks like this - if not then tell me

\frac{18}{ \frac{2 \times 3}{5 - 2} }

2×3=6

5-2=3

Then there's only

\frac{18}{ \frac{6}{3} }

Which is equal to

\frac{18}{1}  \times  \frac{3}{6}  =  \frac{54}{6}  =  \frac{9}{1}  = 9
