Two litres of milk and three loaves of bread cost 101 roubles. Three litres of milk and one loaf of bread cost 85 roubles. Using the information above, we can form the equation:

2m + 3b = 101

where m is the price of a litre of milk and b is the price of a loaf of bread in roubles.

(a) Form another equation using the information from above.

(b) Hence solve the pair of equations to find the values of m and b.

Triangle xyz, with vertices x(-2, 0), y(-2, -1), and z(-5, -2), undergoes a transformation to form triangle x′y′z′, with vertices x′(4, -2), y′(4, -3), and z′(1, -4). the type of transformation that triangle xyz undergoes is a . triangle x′y′z′ then undergoes a transformation to form triangle x′y′z′, with vertices x″(4, 2), y″(4, 3), and z″(1, 4). the type of transformation that triangle x′y′z′ undergoes is a .
