X= -2 and y = -6. Here is the work
Answer:
The statement is not reasonable.
Step-by-step explanation:
Josefina gave away 130% of her stamp collection.
We cannot give more than what we have.
lets understand it mathematically.
suppose i have x stamp.
according to question, i have to give 130% of my stamp collection
130% of x = 130/100 x = 1.3x
so, i have to given 1.3x stamp while i do have only x stamp which does not make any sense.
maximum i can give is x stamp.
x stamp in percentage of my total stamp collection which is also x will be
= x/x*100 = 100%
Thus, maximum one can give is 100% of what he has.
Thus, we can say that Josefina gave away 130% of her stamp collection is not reasonable.
Answer:
D
Step-by-step explanation:
f(x) = 10x - 5 → x = 10g(x) - 5 → x + 5 = 10g(x) →
g(x) = (x + 5)/10
Answer:
b = -6
Step-by-step explanation:
Apply the exponent rule that 
In this case, 
Set that equal to 
:
Apply the exponent rule that 
so now you get:
Since the base is y for both sides of the equation, just set the exponents equal to each other and solve for b.
4b = -24
divide each side by 4 to get:
b = -6
