Answer:
(3, 1)
Step-by-step explanation:
x+5y=8
-x+2y=-1
-------------
7y=7
y=7/7=1
x+5(1)=8
x+5=8
x=8-5=3
Answer: x=3, y=1.
Answer:
(2703/64)^3
Step-by-step explanation:
hello :
(5 1/8 x 5 3/8)^3 = (51×53/8×8) ^3 = (2703/64)^3
4(9) + 3s = 75
36 + 3s = 75
3s = 39
s = 13
The critical values of the function are x = 0 and x = 64
The critical values of a function f(x) are the values of x for which f'(x) = 0.
Given,
f(x) = 
The derivative is found as follows, applying the quotient rule:
f'(x) = ![\frac{[5(x^{4} )(x-8)^{2}-5x^{4} [(x-8)^{2} ]' }{[5(x-8)^{2} ]^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5B5%28x%5E%7B4%7D%20%29%28x-8%29%5E%7B2%7D-5x%5E%7B4%7D%20%5B%28x-8%29%5E%7B2%7D%20%5D%27%20%7D%7B%5B5%28x-8%29%5E%7B2%7D%20%5D%5E%7B2%7D%20%20%7D)
= 
The zeros of the function are the zeros of the numerator, thus:

x - 64 = 0------------->x = 64
The critical values are x = 0 and x = 64
