Your answer can be anything in the form y = mx+8 where you replace m with any real number.
You start with y = mx+b, and then replace the b with the y intercept 8.
The y intercept is where the polynomial crosses the y axis.
The value of m does not matter. So you could have y = 2x+8 or y = 3x+8 for instance. Replace m with whatever your favorite number is.
Since ABCD is a parallelogram, the opposite sides will be parallel and equal,
Consider that AC acts as a transversal to the parallel lines AB and CD, so we can write,
So by the ASA criteria, the triangle AED is congruent to the triangle CEB,
Then the corresponding parts of the triangles will be equal,
Hence Proved.
As a ratio it would be18:14
but as a fraction it would be 18/14
Savings : Spending = 5:8
Sum of ratio = 5 + 8 = 13.
Fraction of savings = 5/13
Fraction of spending = 8/13
Savings is 5/13 * 520 = 5 * 40 = 200
Spending is 8/13 * 520 = 8 * 40 = 320
Savings = £ 200
Spending = £320
