The scale on a map is 1: 20000. the area of a lake on the map is 1.6 square centimetres. calculate the actual area of the lake. give your answer in square metres

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?

Based on the diagrams, what is the value of x?
