Answer:
Step-by-step explanation:
Given
![\frac{8y^{2} }{2\sqrt[4]{y} }](https://tex.z-dn.net/?f=%5Cfrac%7B8y%5E%7B2%7D%20%7D%7B2%5Csqrt%5B4%5D%7By%7D%20%7D)
it can be written as we
=
= 
= 
= 
Therefore the given solution is in the form of k * y^n
Answer:
D. 40 cups
Step-by-step explanation:
10÷2=5
5×8=40
She will use 40 cups of trail mix
A) is 2x
b) is
c) is -2x
I think these are correct.
![log_{10}1000^{x] = log_{10}10^{2x}=2x](https://tex.z-dn.net/?f=log_%7B10%7D1000%5E%7Bx%5D%20%3D%20log_%7B10%7D10%5E%7B2x%7D%3D2x)

Answer and Step-by-step explanation:
7x+1y = 17.00 can be simplified to y = -7x +17
<span>-7x +17 can then be substituted for y in 3x+ 4y =17.50
</span>3x+4(y) = 17.50
3x+ 4(-7x +17) = 17.50
From here you can solve for X
<span>3x + 4(-7x +17) = 17.50
</span>3x -28x + 68 = 17.50
-25x + 68 = 17.50
-68 -68
-25x = -50.50
÷-25 ÷-25
X = 2.02
You can then replace x with 2.02 in the original 7x + 1y = 17.00 to solve for y.
7(x) + 1y = 17.00
7(2.02) + y = 17.00
14.14 + y = 17.00
-14.14 -14.14
y = 2.86
Then substitute 2.02 for x and 2.86 for y in the original 3x+ 4y = 17.50 to check.
3(x) + 4(y) = 17.50
3(2.02) + 4(2.86) = 17.50
6.06 + 11.44 = 17.50
17.50 = 17.50
So
X = 2.02
and
Y = 2.86
or the solution set is (2.02, 2.86)
Hope this helps
