What is X 2x-1 equals -3?
2x-1=-32x=-3+1x=-2/2x=-1
How do you factor 2x squared -1x-6?
(2x + 3)(x - 2)
Graph y equals 2x plus 1?
y = 2x + 1 1. Make a table: x = -2; y = -3y = 2x + 1y = 2(-2) + 1 = -4 + 1 = -3 x = -1; y = -1y = 2x + 1y = 2(-1) + 1 = -2 + 1 = -1x = 0; y = 1y = 2x + 1y = 2(0) + 1 = 0 + 1 = 1 x = 1; y = 3y = 2x + 1y = 2(1) + 1 = 2 + 1 = 3 x = 2; y = 5y = 2x + 1y = 2(2) + 1 = 4 + 1 = 5 2. Plug the points (-2, -3), (-1, -1), (0, 1), (1, 3), and (2, 5) in a xy-coordinate system. 3. Draw a line which passes through those points. Thus, the line drawn is the graph of the function y = 2x + 1
What is a 2 step equations that equal 1?
A 2-step equation that equals 1 could be represented as 2x - 1 = 3. In this equation, you would first add 1 to both sides to isolate the variable term, resulting in 2x = 4. Then, you would divide by 2 on both sides to solve for x, giving the final answer of x = 2.
What is 2x-2 plus 3?
2x+1 because -2 +3 = 1
