Answer:

I think its b

Step-by-step explanation:

by moving it 5 units down, A' will become (-4,-4), and a 180° would make A'' (4,4). (I haven't taken geometry in a few years, so if im wrong, I'm sorry)

Help, hurry up please

For this case we must find an expression equivalent to:

\frac {\sqrt [7] {x ^ 2}} {\sqrt [5] {y ^ 3}}

By definition of properties of powers and roots we have:

\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}

So, rewriting the expression we have:

\frac {x ^ {\frac {2} {7}}} {y ^ {\frac {3} {5}}} =

By definition of power properties we have:

a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}

So:

x ^ {\frac {2} {7}} * y ^ {- \frac {3} {5}}

Answer:

Option A

Simplify -3/5x+1/2x and explain how you got it please
Licemer1 [7]

Answer:

-(1/10)x

Step-by-step explanation:

This is an addition problem.  Since the variable (x) is the same in both terms, we need only sum up the coefficients -3/5 and 1/2 and then multiply x by this sum.

-3/5x+1/2x = (-3/5 + 1/2)x

The LCD of -3/5 and 1/2 is 10.  The -3/5 term converts to -6/10 and the 1/2 term to 5/10.  Thus, we have (-6/10 + 5/10)x = -(1/10)x
