Select the correct answer from each drop-down menu. Sue downloads music videos on her phone.
The cost of the video downloads (in dollars) is given by the equation c = 2v, where c is the total cost of the videos and v is the number of videos. The constant of proportionality in the equation in terms of cost per video is
. In this example, the constant of proportionality is also the
of the videos.

Every time you drive you will experience a combination of driving conditions and environments.

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.
