Solve the system of equations below by using substitution. Show your steps and the solutions for both variables.
2x + 4y = 20
y = 3 - x

Both question plz I need help

If the table of the function contains exactly two potential turning points, one with an input value of –1, which statement best describes all possible values of m? m ≥ –12 –12 < m < 4 m ≤ 4 m ≥ 4 or m ≤ –12

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14

Which of these triangle pairs can be mapped to each other using a single translation? cof hn
