y = x² + ax + bWhen x=1:47 = (1)² + a(1) + b47 = 1 + a + b46 = a + bWhen x = 260 = (2)² + a(2) + b60 = 4 + 2a + b56 = 2a + b Let this be equation 1Let 46 = a + b be equati...

100 + (3.5 x 15) = 152.50 100 x 1.03¹⁵ = £155.80 Therefore he should choose savings account B because after 15 years he will have gained more money through interest than in account A...

As we know that AC = AB, then it must be the case that BC is the base of the triangle (because it is isosceles). Therefore, the line of symmetry of the triangle ABC goes through the point A, and is perpen...

Y= mx + cFinding m : change in y/ change in x => (8--7)/(3--2) = 3Finding c : input a pair of coordinates => 8 = (3 x 3) + c .... c = -1y = 3x -1
