a) We can get the result by calculating the common ratio between elements 1 and 2, and 2 and 3. R_n = 1/√x-1 /Ratio between 1st and 2nd R_n = √x + 1 /Ratio between 2nd...

Trade is the international exchange of goods and services. An economy can engage in trade because of the variation of production efficiency between countries, it is able to export goods it produces at a r...

35x + 6x + 3b ≡ ax + 13 41x + 3b ≡ ax + 13 when x=0 3b + 40 = 13 3b= -27 b=-9 so 41x - 27 + 40 ≡ ax + 13 when x = 1 41-27 + 40 = a + 13a = 41

We commonly solve this via the method of substitution. We label each equation i and ii. We then solve the first equation i for a single variable. We then substitute this value into the secod equation, and...

If two lines are parallel they have the same gradient so we must find the gradient of line B and use it to find line ALine B ==> 2y - 3x + 4 = 0This can be rearranged in to the form "y = mx + c&qu...
