We have
We start by calculating square root:
We can rewrite 4 in base of 2:
Now we can calculate this by using rule of same base and different exponent:
Answer:
range={4,5,5} and its a function
Step-by-step explanation:
its a function becoz the domain are not repeated
Answer:
perfect square roots is when you have two of the same number that if you multiply them you get it. Example: the square root of 36 is six, because six times another six is 36- so 36 is a perfect square root number. 20 doesn't have a perfect square root because there are no two of the same numbers that will get you 20.
First blank 4 —> (4,7)
Second blank 3 —> (-4,3)
Third blank -2 —> (-2,4)
Answer:
Step-by-step explanation:
4. 10x + 30 = 90
10x = 60
x = 6
complementary
5. 4x + 40 + 3x = 180
7x + 40 = 180
7x = 140
x = 20
