Answer:
i think its b srry if im wrong
Step-by-step explanation:
B^2 + b = 2
b^2 + b + 1/4 = 2 + 1/4
(b + 1/2)^2 = 9/4
b + 1/2 = (+-) sqrt 9/4
b + 1/2 = (+-) 3/2
b = -1/2 + 3/2 = 2/2 = 1
b = -1/2 - 3/2 = -4/2 = -2

Answer:
80, 40, 40
Step-by-step explanation:
The rule is if the number before the tens place is 5 or more round up and if it is 4 or less round down.
I like to look at it without the rule and what makes sense.
82.14: my choices are 80 or 90. What number is 82.14 closer to on the number line? 80.
38.5 The choices are 30 and 40. This number on a number line would be closer to 40
41.3 The choices are 40 and 50. On a number line this number would be closer to 40.
The right answer for the question that is being asked and shown above is that: "y = x/26 and y = -0.030(x-500)2+15,900." A company plans to sell bicycle helmets for $26 each. The company's business manager estimates that the cost, y, of making x helmets is a quadratic <span>function with a y-intercept of 8,400 and a vertex of (500, 15,900).</span>
