a plumber charges a consultation fee of $25 then charges $60 an hour. write a linear equation to model this situation.

a.

y = 60x + 25

b.

y = 25x + 60

c.

c = 25x + 60y

d.

c = 60x + 25y

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.

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

Find the solution of each of the following.
