find the real solutions. 2+the square of (9x-8)=x
Math the equation a single logarithm. Express as factors. ln(x/(x-1))+ln((x+1)/(x))-ln(x^2-1)
Solve the equation. 2log_2(x-5)+log_2(2)=5
The marginal cost of a product can be thought of as the cost of producing one additional unit of output. For example, if the marginal cost of producing the 50th product is $6.20, it cost $6.20 to increase productionn from 49 to 50 units of output. Suppose the marginal cost C(i...
solve the logarithmic equation. log(5x+7)=1+log(x-9)
Factor the following. 3x^3+49=x^2+147x
find all points having an x-coordinate of 2 whose distance of the point (-1-2)is 5.
Find the real solutions by factoring. 3x^3+16=x^2+48x
By the way it's not my homework. It's just something i need to prepare for my text next week.
I've no idea of what i should write
