Answer:
Step-by-step explanation:
Any number equal to or greater than 20 is a solution. 22 would be a solution.
Answer: D. 7^11
Step-by-step explanation:
For exponents with the same base, we just add the exponents and keep the same base. 7 is the same base; therefore 5+6=11 which means the answer is 7^11
Answer:
We use the power rule of exponents to find out that both sides of the equation equal 3^20 (or 3486784401).
Step-by-step explanation:
For this example, we can just use a calculator and find out that both (3^5)^4 and (3^4)^5 are the same value. But how do we know this algebraically?
When dealing with exponents, we must have a good understanding of the properties of exponents before doing any calculations.
For this example, I recognize that the power rule of exponents is being used:
So let's apply this rule to the given equation.
(3^5)^4 = (3^4)^5
3^(5*4) = 3^(4*5)
3^20 = 3^20
Now we know both sides of the equation equal 3^20 (or 3486784401).
Answer:
Y=1/2x+3. Y=3/2x-1
Step-by-step explanation:
Answer:
x = -8
Step-by-step explanation:
3(1.5x + 9) = -9
Divide both sides by 3
1.5x + 9 = -3
Subtract 9 from both sides
1.5x = -12
Divide both sides by 1.5
x = -8
