31 miles an hour just divide 527 by 17
Answer:
The correct answer is distributive postulate.
Step-by-step explanation:
Look at the expression we have given:
3x + 3 = 3(x + 1)
And we are asked that which postulate is illustrated for the real numbers.
We know that the distributive property of multiplication states that we can multiply a sum of numbers by multiplying each addend separately and finally add the products.
a*(b+c)= a*b+a*c
where a,b and c are real numbers.
3(x+1)= 3*x+3*1 = 3x+3
Therefore the correct option is distributive postulate....
Domain is: D = all real numbers
and Range is: R = {y | y > 0}
Option C is correct.
Step-by-step explanation:
We are given a function and we need to find domain and range of this function
Domain:
The domain of a function is the set of points for which the function is real and defined.
Since all the values give the result which is real and defined so domain is all real numbers.
Range:
The set of values of the variable that is dependent, the function should be defined.
So, all the values should be greater than 0 i.e {y | y > 0}
So, Domain is: D = all real numbers
and Range is: R = {y | y > 0}
Option C is correct.
