The answer is x=7 hope this helps:)
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
7) y = 4x
8) y = 7x/8
9) y = 25x/3
I think this are the answers.
Answer: 1625
Step-by-step explanation: So if you want to make 13 of one recipe it said that in 1 recipe there's 125 cups of sugar so you need to multiply 123 by 13 so do this 125 x 13 = 1625 and then there, you have your answer 1,625 cups of sugar for 13 things of the recipe.
For this case we must find the product of the following expression:
![\sqrt {12} * \sqrt {18}](https://tex.z-dn.net/?f=%5Csqrt%20%7B12%7D%20%2A%20%5Csqrt%20%7B18%7D)
We combine using the product rule for radicals:
![\sqrt [n] {a} * \sqrt [n] {b} = \sqrt [n] {ab}](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%7D%20%2A%20%5Csqrt%20%5Bn%5D%20%7Bb%7D%20%3D%20%5Csqrt%20%5Bn%5D%20%7Bab%7D)
So, we have:
![\sqrt {12 * 18} =\\\sqrt {216} =](https://tex.z-dn.net/?f=%5Csqrt%20%7B12%20%2A%2018%7D%20%3D%5C%5C%5Csqrt%20%7B216%7D%20%3D)
We rewrite the 216 as![6 * 6 * 6 = 6 ^ 3 = 6 ^ 2 * 6](https://tex.z-dn.net/?f=6%20%2A%206%20%2A%206%20%3D%206%20%5E%203%20%3D%206%20%5E%202%20%2A%206)
![\sqrt {6 ^ 2 * 6} =](https://tex.z-dn.net/?f=%5Csqrt%20%7B6%20%5E%202%20%2A%206%7D%20%3D)
By definition of properties of powers and roots we have:
![\sqrt [n] {a ^ n} = a ^ {\frac {n} {n}} = a](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20n%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bn%7D%20%7Bn%7D%7D%20%3D%20a)
Then, the expression is:
![6 \sqrt {6}](https://tex.z-dn.net/?f=6%20%5Csqrt%20%7B6%7D)
