question he
the linear function d(t) = 7 - 2t gives your distance d (in miles) from home,
hours after you leave the library,
a. sketch a graph of the function. write the domain and range in inequalities
for (1) in this context.
b. what are the intercepts of the graph? explain the meaning of any
intercepts in this context.
(a) use the graphing tool to graph the linear equation
the domain for d(t) in this context is
(type an inequality using t as the variable. type an inequality or a compound
inequality. use integers or fractions for any numbers in the inequality.)

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.
