Answer:
A. y=1-2x
Step-by-step explanation:
-1 =1-2(1)
-1= 1-2
-1=-1
-3=1-2(2)
-3=1-4
-3=-3
-5=1-2(3)
-5=1-6
-5=-5
-7=1-2(4)
-7=1-8
-7=-7
Answer: 13/1, 195/15, 130/10
Step-by-step explanation: The easiest way to solve this problem is to work your way though each of the options. 13/1 is the original reduced by 5, 195/5 is both multiplied by 3 and 130/15 is both multiplied by 2. The other two options do not have a way to multiply or divide them to get the original number.
Answer: B) (96pi + 160) cm2
Step-by-step explanation:
Answer:
[7^(1/3)]^3 = 7^(1/3) * 7^(1/3) * 7^(1/3)=7^(1/3 + 1/3 + 1/3)=7^(3/3) =7^1=7
The last option is the correct one
Explanation:
Te given is:
[7^(1/3)]^3 which means that we will multiply 7^(1/3) by itself three times
So, the first step is:
[7^(1/3)]^3 = 7^(1/3) * 7^(1/3) * 7^(1/3)
Now, when multiplying numbers with same base, the powers are added together.
Here, we have the same base (7), so we will add the powers.
So, the next step is:
7^(1/3) * 7^(1/3) * 7^(1/3) = 7^(1/3 + 1/3 + 1/3)
Now, 1/3 + 1/3 + 1/3 = 3/3 which is equal to 1
So, the third step is:
7^(1/3 + 1/3 + 1/3)=7^(3/3) =7^1
Finally, any base raised to the power of one would be equal to itself.
So, the final step is:
7^(3/3) =7^1=7
Concatenating all the previous steps, we will find that the complete scenario is:
[7^(1/3)]^3 = 7^(1/3) * 7^(1/3) * 7^(1/3)=7^(1/3 + 1/3 + 1/3)=7^(3/3) =7^1=7
Hope this helps :)
