- (a + 5) = 49 x +5 2.arrow_forwardAn object is thrown upward at a speed of 109 feet per second by a machine from a height of 10 feet off the ground. The height h(t) after t seconds can be found using the equation h(t) = −16t 2 + 109t + 10. A) When will the height be 143 feet? B) When will the object reach the ground?arrow_forwardDivide −4x2−2x+14 by 2x+3 Write your answer in the form: −4x2−2x+14=(2x+3)×q(x)+r(x) −4x2−2x+14arrow_forward
- The following equation is given. Complete parts (a)-(c). -3x-25x+ 75 = 0 b. Use synthetic division to test several possible rational roots in order to identify one actual root. One rational root of the given equation is (Simplify your answer.) c. Use the root from part (b) and solve the equation. The solution set of x-3x - 25x + 75=0 is (Simplify your answer. Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expressic Enter your answer in each of the answer boxes.arrow_forwardFind The Domain and Rang X+ 2 y = 131 x²- 3 2.arrow_forwardTwo cars travel to Edmonton at the same time. Car A travels 240 km in the same time it takes Car B to travel 180 km. Car A travels an average of 25 km/h faster than Car B. A rational equation that relates the average 240 180 v+25 speeds of the two cars is: - V where v kilometres per hour is the average speed of Car B. Determine the average speed of the fastest car, to the nearest kilometre per hour. Finis Answer:arrow_forward
