It is a percentage because it can be written as a fraction
Answer:
-1, 6
Step-by-step explanation:
x + y = 5
xy = -6
Take first equation and rewrite it. y = -x + 5
Then substitute the new equation in the second one.
x(-x + 5) = -6
-x^2 + 5x + 6 = 0
Divide by -1
x^2 - 5x - 6
(x + 1)(x - 6) = 0
x = -1, 6
IGNORE THE SQUARE ON THE GRAPH
a trapezium is a quadrilateral with parallel sides
see how you could draw that
and match the coordinate to the y in (-3,3) and then use the reciprocal of -3 as the x coordinate
your final plot points would be (3,3)
plot this point and join up your coordinates.
