Answer:
Step-by-step explanation:
This problem is all about bases and exponents. Because we have a quotient and the bases are both 5's, that means that we can use the rule of exponents for quotients to rewrite and simplify:
That's the simplification as long as you are "allowed" to leave the exponent as a negative number.
Answer:
y= x/zw
Step-by-step explanation:
Isolate the variable by dividing each side by the factors that dont contain the variable
x = zyw /zw
y=x/zw
3.) A *the first one*
4.) C *the last one*
Answer:
X=-1,y=-2
Step-by-step explanation:
if y =2x
2x=4x+2
so X=-1 and y=-2
29-11=18
18²+18²=p²
324+324=p²
p²=648
p=18√2
That's your answer.
