Is g(x)= 5 + 6/x a linear function?

No it is not linear. The fact that x is in the denominator indicates that it won't be linear. If you graph this out, you'll get a curved hyperbola which is not a straight line.

Linear equations are of the form y = m*x + b where m and b are fixed numbers. For example y = 2*x + 5 is a linear equation (in that case m = 2 and b = 5).

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
