Find the equation in standard form of the line passing through the points (2, -3) and (4,2) (answer)

y - y1 = y2 - y1 x - x1 x2 - x1 y + 3 = 2 + 3 = 5 x - 2 4 - 2 2 Cross multiply. 2(y + 3) = 5(x - 2) 2y + 6 = 5x - 10 0 = 5x - 2y - 16

m = y2 - y1 x2 - x1 m = -11 - 4 = -15/0 6 - 6 Division by zero is undefined. Lines with an undefined slope are vertical lines. So, x = 6

Let x = the measure of the second angle Let (1/2)x = the measure of the smallest angle Let 4(1/2)x+ 68 = the measure of the largest angle x + (1/2)x + 4(1/2)x + 68 = 180 (3 1/2)x = 112 (7/2)x = 112 x = 32º (1/2)x = 16º 2x + 68 = 132...

Let x = the number of parked motorcycles Let y = the number of parked cars x + y = 500 y = 500 - x 2x + 4y = 1650 2x + 4(500 - x) = 1650 2x + 2000 - 4x = 1650 -2x = -350 x = 175 motorcycles y = 500 - 175 y = 325 cars

When h = 2, what does t equal? (answer)

Let x = the first consecutive even integer Let x + 2 = the second consecutive even integer Let x + 4 = the third consecutive even integer x + 2 + 3x = 2(x + 4) - 2 4x + 2 = 2x + 8 - 2 4x + 2 = 2x + 6 2x = 4 x = 2 x +...

Since a rhombus is a parallelogram, the opposite angles are congruent. Also, the sum of all four angles is 360º. So, the four angles would be 50º, 50º, 130º, and 130º.

m∠A + 48 = 180 m∠A = 132º
