Easy peasy, this is a representation of differnce of 2 perfect squares
a^2-b^2=(a-b)(a+b)
4 < = x + 4 < = 8
4 - 4 < = x + 4 - 4 < = 8 - 4
0 < = x < = 4.......this matches ur graph
so ur expression is : x + 4
Answer: When your walk or run
Step-by-step explanation: When you walk or run, you take steps and those steps calculate to feet yards mabe even miles.... This was very ez
Step 1: Add the two equations.
Step 2: Solve for x.
Step 3: To find the y-value, substitute in 3 for x in one of the equations.
Step 4: Solve for y.
Step 5: Identify the solution as an ordered pair.
What if adding or subtracting does not eliminate a variable? Example. 3x – y = 8. x + 2y = 5.
