Activity 1.5 The Secret FORMULA! a. Find the value of a, b and c in the following quadratic equations.
Quadratic Equation a b c
1. x2 − 4x− 5 = 0
2. 2x2 + x− 6 = 0
3. x2 − 3x = −1
4. x2 − 6x = −2x + 7
5. −2x = −3x2 + 8

b. Using the given quadratic equations above, find the roots using quadratic formula. Simplify your
answer.

(least common multiples) the answer that i had in the 1st step was lcm of airline tickets sold=72. idk if that even matters but just in case. ! three co-workers are busy selling airline tickets over the phone. in an 8-hour day, charles can sell 8 airline tickets, ann can sell 9 airline tickets, and michelle can sell 6 airline tickets. step 2 of 2: what is the smallest number of 8-hour days needed for each of them to achieve the same number of sales? it takes charles . it takes . it takes .

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2
