8x+(4*30)=6(6+30)
8x+120=6x+180
2x=60
x=30 pounds of coffee
7(h-4) = 2h + 17 distribute to get:
7h - 28 = 2h + 17 subtract 2h from both sides to get:
5h - 28 = 17 add 28 to both sides to get:
5h = 45 divide 5 from both sides to get:
h = 9

The derivative is the rate of change of a function, basically represents the slope at different points. To find the derivative of the given function you can use the power rule, which means, if n is a real number, d/dx(x^n)= nx^(n-1). This is a simplification of the chain rule based on the fact that d/dx(x)=1. Anyway, this means that d/dx(x^3 + 1)= 3x^2. Here n is 3 and so it is 3*x^(3-1)= 3x^2. The derivative of x^3+1 is 3x^2.
If you are wondering what happened to the 1, for any constant C, d/dx(C)=0.
Answer:
The solution is 
. Fourth option
Explanation:
Solve for x:
Move all the terms from the right to the left side of the equation, a zero in the right side:
Join all like terms:
The general form of the quadratic equation is:
Solve the quadratic equation by using the formula:
In our equation: a=1, b=-2, c=-46
Substituting into the formula:
Since 188=4*47
Take the square root of 4:
Divide by 2:
