Answer:
x = -1.8
Step-by-step explanation:
10(-1.8) - 2 = -18 - 2 = -20
so X = -1.8
Answer:
Option D is correct.
Step-by-step explanation:
We are given ![\sqrt[5]{x^7}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%5E7%7D)
We know that![\sqrt[5]{x} = x^\frac{1}{5}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%7D%20%3D%20x%5E%5Cfrac%7B1%7D%7B5%7D)
and we are given:
![\sqrt[5]{x^7}\\ We\,\, can\,\, write\,\, as\,\,\\x^\frac{7}{5}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%5E7%7D%5C%5C%20We%5C%2C%5C%2C%20can%5C%2C%5C%2C%20write%5C%2C%5C%2C%20as%5C%2C%5C%2C%5C%5Cx%5E%5Cfrac%7B7%7D%7B5%7D)
So, Option D is correct.
12 out of 30 % because if you add 12+20+8= it equals 30 and they said there are 12 blueberry muffins.
Eight less than. I hope this helped. Keep up the good work
Answer:
(x, y) = (4, 3)
Step-by-step explanation:
The second equation gives an expression for y that can be substituted into the first equation.
... 2x -3(x -1) = -1 . . . . put x-1 where y was
... -x +3 = -1 . . . . . . . simplify
... 4 = x . . . . . . . . . . . add x+1
Using that second equation, we can find y to be ...
... y = 4 -1 = 3
The solution is (x, y) = (4, 3).
