Root 25 is the rational number as it equals 5
Let x be the number of Hamburger so, the number of cheeseburger = 544-x
The equation is then 3x = 544-x & x=136
The total amount that Chang will received from his wages is the product of his hourly wage times the number of hours he has worked (n). His total savings should not be less than $125. The equation that best describes the situation is,
45 + 7n ≥ 125
Solving for n in the inequality gives an answer of n≥11.42 hours. Thus, he needs to work for at least 12 hours.
Answer:
15/56x^(-4/7) + 32x^3 + 6.
Step-by-step explanation:
Using the rule for algebraic differentiation:
If y = ax^n, dy/dx = anx^(n-1).
So :
If y = 5/8x^3/7 + 8x^4 + 6x - 9
dy/dx = 5/8* 3/7 x^(3/7-1) + 8*4 x^(4-1) + 6x(1-1)
= 15/56x^(-4/7) + 32x^3 + 6.
