Question

Determine whether the point (1,5) is a solution to the system of inequalities below
y>3x
Y>2x+1

Answer 1

thats for the second one

Answer 2

9x^4.

Answer 3

plug in 5 for y and 1 for x and see if the inequalities are true and they are

Answer 4

4x + 7 = 9x - 4
9x - 4x = 7 + 4
5x = 11
x = 11/5 or 2 1/5

Answer: x = 11/5 or 2 1/5

Proof:
4(11/5) + 7 = 9(11/5) - 4
44/5 + 35/5 = 99/5 - 20/5
79/5 = 79/5
