Adata analyst for a phone company is analyzing the data of 150 of their customers, which accounts for 1% of their total customers. the analyst wants to determine the average number of hours each day a customer uses their phone, for calls and for texts, during a 30-day period. based on the data, the customers averaged 0.25 hours per day per call and 1.75 hours each day for texts. construct an equation in the correct form to represent this situation. let t represent the number of calls made per day, and e represent the total number of hours a customer uses their phone each day.

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.

Which shows the correct substitution of the values a, b and c from the equation 1=-2x+3x^2+1

What does the sign of the slope tell you about a line?
