Answer:
x = 
, y = 6
Step-by-step explanation:
5x + y = 7 → (1)
20x + 2 = y → (2)
Substitute y = 20x + 2 into (1)
5x + 20x + 2 = 7
25x + 2 = 7 ( subtract 2 from both sides )
25x = 5 ( divide both sides by 25 )
x = 
=
Substitute this value into (2) and evaluate
20( ) + 2 = y
4 + 2 = y , so
y = 6
This is a perfect square parabola
f(x) = (2x + 5)^2
the graph will be a parabola opening upwards and will touch the x-axis at x = -2.5
