Use inductive reasoning to predict the next line in the pattern. Then perform the arithmetic to determine whether your conjecture is correct.(6 × 1) × (2 × 1) = 12(6 × 10) × (2 × 2) = 240(6 × 100) × (2 × 3) = 3600
A. (6 × 1000) × (2 × 4) = 4800 B. (6 × 1000) × (2 × 4) = 48,000 C. (6 × 1000) × (2 × 4) = 42,000 D. (6 × 1000) × (2 × 4) = 54,000
Two sides and an angle are given. First, determine whether the given information results in no triangle, one triangle, or two triangles. Solve each resulting triangle.A = 30°, a = 22, b = 44
A. no triangle B. one triangle; B = 90°, C = 60°, c = 38.1 C. one triangle; B = 60°, C = 60°, c = 38.1 D. one triangle; B = 60°, C = 90°, c = 38.1
Use the graph of f to sketch a graph of the inverse of f using a dashed curve.
A. 
B.

Solve the system mentally, without the use of a calculator or pencil-and-paper calculation. Try to visualize the graphs of both lines.x + 0y = 90x + y = 4
A. x = 9; y = 4
B. x = 4; y = 9
C. x = 9; y = 2
D. x = 2; y =
