You need a total of 50 pounds of two types of ground beef costing $1.25 and $1.60 per pound, respectively. a model for the total cost y of the two types of beef is y = 1.25x + 1.60(50 − x) where x is the number of pounds of the less expensive ground beef. a) find the inverse function of the cost function. what does each variable represent in the inverse function? b) use the context of the problem to determine the domain of the inverse function.

a mix with a total cost of x=$73.

Of course, 30 pounds (50 pounds - 20 pounds = 30 pounds) of that mix will be the more expensive ground beef.

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
