Beta-blockers, alpha2-adrenergic agonists, and thiazide diuretics are associated with libido changes. Testosterone is the main hormonal mediator of a manâs libido. As testosterone levels decline, sexual desire decreases; therefore medications that affect testosterone can alter the libido. Finasteride and dutasteride, 5-alpha reductase inhibitors for the treatment of benign prostate hyperplasia (BPH), decrease dihydrotestosterone levels, the active metabolite of testosterone.
Solving an equation symbolically means that expressions that may contain known variables or possibly also variables not in the original equation are admitted as solutions. For example, the equation x + y = 2x â 1 is solved for the unknown x by the solution x = y + 1, because substituting y + 1 for x in the equation results in (y + 1) + y = 2(y + 1) â 1, a true statement.
Find the equation of the line determined by $A(-2, 4)$ and $B(3, -2)$ . Solution: In this example we have: $ x_A = -2,~~ y_A = 4,~~ x_B = 3,~~ y_B = -2$ . So we have: Multiply both sides with $5$ to get rid of the fractions.In special case (when $x_A = x_B$ the equation of the line is: Example 2: Find the equation of the line determined by $A(2, 4)$ and $B(2, -1)$ .Solution: In this example we have: $ x_A = 2,~~ y_A = 4,$ $ x_B = 2,~~ y_B = -1$ . Since $x_A = x_B$ , the equation of the line is: You can see from picture on the right that in special case the line is parallel to y-axis.ind the equation of the line determined by $A(-2, 4)$ and $B(3, -2)$ . Solution: In this example we have: $ x_A = -2,~~ y_A = 4,~~ x_B = 3,~~ y_B = -2$ . So we have: Multiply both sides with $5$ to get rid of the fractions.
