Explanation Given: The expression is 12.4 × 7 = 6.2 × _ . Approach: The decimal number 12.4 is divided by 2 in the right side of the equation. Thus the 2 has to be compensated with the other number 2 by multiplying by 2 . Calculation: Calculate the number to fill the blank. To determine (b) To find: The number to fill in the blank 12.4 ÷ 0.2 = _ . To determine (c) To find: The term to fill in the blank a b = ( a .10 − 1 ) _ . To determine (d) To find: The number to fill in the blank 12.3 = 10 − 2 × _ .

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

7. [10 marks] Let G = (V,E) be a 3-connected graph. We prove that for every x, y, z Є V, there is a cycle in G on which x, y, and z all lie. (a) First prove that there are two internally disjoint xy-paths Po and P₁. (b) If z is on either Po or P₁, then combining Po and P₁ produces a cycle on which x, y, and z all lie. So assume that z is not on Po and not on P₁. Now prove that there are three paths Qo, Q1, and Q2 such that: ⚫each Qi starts at z; • each Qi ends at a vertex w; that is on Po or on P₁, where wo, w₁, and w₂ are distinct; the paths Qo, Q1, Q2 are disjoint from each other (except at the start vertex 2) and are disjoint from the paths Po and P₁ (except at the end vertices wo, W1, and w₂). (c) Use paths Po, P₁, Qo, Q1, and Q2 to prove that there is a cycle on which x, y, and z all lie. (To do this, notice that two of the w; must be on the same Pj.)
