The point-slope form of the equation of the line that passes through (–4, –3) and (12, 1) is y – 1 = (x – 12). What is the standard form of the equation for this line? x – 4y = 8 x – 4y = 2 4x – y = 8 4x – y = 2 Answer: x - 4y = 8 Step-by-step explanation: first, get the slope (m) m = (1- -3 )/ (12 - -4) = 4 / 16 = 1/4 substitute to the point-slope form of the equation y - 1 = m(x - 12) y- 1 = (1/4) (x - 12) multiply both sides with 4 4y - 4 = x -12 transform to standard form x - 4y = 8

Calculate the area of glass in a table that consists of three glass circles.the largest circle has a diameter of 68cm. The diameters of the other two circles are 6and 10 cm less than the diameter of the largest circle. Give your answer correct to 2 decimal places. Answer: 9292.83 cm² Step-by-step explanation: Calculate the area of glass in a table that consists of three glass circles.the largest circle has a diameter of 68cm. The diameters of the other two circles are 6 and 10 cm less than the diameter of the largest circle. Give your answer correct to 2 decimal places. D= diameter ; r = radius D1 = 68 cm ; r1 = 0.5(D1) = (0.5)(68 cm) = 34 cm D2 = 68 cm - 6 cm = 62 cm ; r2 = 0.5(D2) = (0.5)(62 cm) = 31 cm D3 = 68 cm - 10 cm = 58 cm ; r3 = 0.5(D3) = (0.5)(58 cm) = 29 cm A = π(r1)² + π(r2)² + π(r3)² A = π(34 cm)² + π(31 cm)² + π(29 cm)² A = 2958π cm² = 9292.83 cm²
