As Mark commented, it is almost impossible to answer without a diagram. However, I am going to describe a particular situation and give you a proof. Let's call the transversal, the line that crosses l and m, line t. ∠1 lies above line l and to the left of line t. ∠7 lies below line m and...

Example: 3 1/2 + 4 2/3 = 3 3/6 + 4 4/6 = 7 7/6 = 8 1/6     You must change the fractions to the same common denominator.

y = (-1/2)x2 - 3x + 5/2 In the general form of a quadratic, y = ax2 + bx + c, c represents the y-intercept. So, the y-intercept for this equation is 5/2.   To find the x-intercepts, let y = 0 and solve for x. 0 = (-1/2)x2- 3x + 5/2   Multiply both...

Word problem (answer)

Let x = the amount invested at 7% Let y = the amount invested at 2% x + y = 1600       y = 1600 - x .07x + .02y = 82      Multiply both sides by 100 to get rid of the decimal points. 7x + 2y = 8200 7x + 2(1600-x) = 8200 7x...
