Visualize the problem. We will have to use the distance formula: d = √(x₂ - x₁)² + (y₂ - y₁)² Let the unknown point be (x,y). The solution is as follows: Distance between A and the point. 3 = √(4 - x₁)² + (8 - y₁)² 9 = 16 - 8x₁ + x₁² + 64 - 16y₁ + y₁² --> eqn 1 Distance between point and B 1 = √(14 - x₁)² + (10 - y₁)² 1 = 196 - 28x₁ + x₁² + 100 - 20y₁ + y₁² --> eqn 2 Subtract eqn 2 from eqn 1: 8 = -180 + 20x₁ - 36 + 4y₁ 8 = -216 + 20x₁ + 4y₁ 224 = 20x₁ + 4y₁ 56 = 5x₁ + y₁ --> eqn 3 The last equation would be the linear equation using points A and B. m = (10-8)/(14-4) = 1/5 = (8 - y₁)/(4 - x₁) 4 - x₁ = 5(8 - y₁) 4 - x₁ = 40 - 5y₁ -36 = x₁ - 5y₁ --> eqn 4 Solve equations 3 and 4 simultaneously: x₁ = 9.38 y₁ = 9.08<em>Therefore, the closest answer is letter B.</em>

Answer:
Step-by-step explanation:
factor each term into powers of primes
75 = 3×5²
20 = 2²×5
Greatest common factor = 5
75+20 = 5(15+4)
Step-by-step explanation:
y+x(x-y)-5
substitute: -7+3(3+7)-5
-7+3(10)-5
-7+30-5
22
If this isn't correct, then use distributive property on 3(3+7)
If so then it would be -7+9+21-5
It would be the same answer, just a different way of finishing it
