Answer:
x = y⁴ does not represent y as a function of x
Step-by-step explanation:
Let's first isolate this equation for the 'y' value :
![\mathrm{Switch\:sides} : y^4=x,\\\mathrm{For\:}x^n=f\left(a\right)\mathrm{,\:n\:is\:even,\:the\:solutions\:are\:}x=\sqrt[n]{f\left(a\right)},\:-\sqrt[n]{f\left(a\right)} : y=\sqrt[4]{x},\:y=-\sqrt[4]{x}](https://tex.z-dn.net/?f=%5Cmathrm%7BSwitch%5C%3Asides%7D%20%3A%20y%5E4%3Dx%2C%5C%5C%5Cmathrm%7BFor%5C%3A%7Dx%5En%3Df%5Cleft%28a%5Cright%29%5Cmathrm%7B%2C%5C%3An%5C%3Ais%5C%3Aeven%2C%5C%3Athe%5C%3Asolutions%5C%3Aare%5C%3A%7Dx%3D%5Csqrt%5Bn%5D%7Bf%5Cleft%28a%5Cright%29%7D%2C%5C%3A-%5Csqrt%5Bn%5D%7Bf%5Cleft%28a%5Cright%29%7D%20%3A%20y%3D%5Csqrt%5B4%5D%7Bx%7D%2C%5C%3Ay%3D-%5Csqrt%5B4%5D%7Bx%7D)
So as you can tell, we have two functions. However, they can be rewritten as one function, y = ± ⁴√x. As we have two values of x that correspond to one value of y, this relation is not a function.
Solution: x = y⁴ does not represent y as a function of x
Answer:
3w+7=31
Step-by-step explanation:
Subtract 7 on both sides
3w+7=31
-7 -7
Divide by 3 on both sides
3w=24
/3 /3
w=8
Hopefully, this helps! :)
15 - 2x = 3x
15 = 3x + 2x
15 = 5x
5x = 15
x = 15/5 = 3
3 plus 5 plus 2 is 10 because if you add 3 plus 5, it equals to 8 and 8+2 equals to 10.
I'm pretty sure it's 70 degrees.
