Your friend found that two rational expressions each simplified to 5/x+3. Are the two rational expressions equivalent? Explain.

The answer is below

Step-by-step explanation:

A rational expression is the ratio of two polynomials. Rational expressions are fractions such that the numerator and denominator are polynomials.

Since there are two rational expressions which can each be simplified to 5 / (x + 3), hence both of the expressions are equivalent to each other. This means that in both of the expressions, each has a numerator that can be simplified to 5 and has a denominator that can be simplified to x + 3.    

the answer is the third / last answer

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
