Two functions are defined by these equations: f(x) = 5.1 +0.8x
g(x) = 3.4 +1.2x
1) If x is 3.9, which function has a greater value?
2) How much greater is the greater value function compared to the lesser function
function at x = 3.9?

.

step-by-step explanation:

.

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
