Answer:
C
Step-by-step explanation:
So we have:
To simplify, we can use the quotient rule of exponents, which says that if we have:
Then this equals:
So, our equation will be:
Subtract the exponents. Turn 1/5 into 2/10 by multiplying both layers be 2. Thus:
Subtract in the exponent:
So, our answer is C :)

Answer: X= -9
Step-by-step explanation:
Multiply the 5 by x+4 then copy the -3x+3=5. It will be 5x+20-3x+3=5.
Then subtract or add the like terms
5x-3x and 20+3. It will be 2x+23=5
Then add -23 to both sides
It will be 2x+23-23=5-23 then solve it will be 2x=-18 then divide both sides by 2 to find the value of x
2x/2=-18/2 then the final answer is x= -9. I hope it help
This is C. cos Z = sin (90 - Y)
