Lee and barry play a trivia game in which questions are worth different numbers of points. if a question is answered correctly, a player earns point. if a question is answered incorrectly, the player loses points. lee currently has -350 points.
a. before the game ends, lee answers a 275 point question correctly, a 70 point question correctly, and a 50 point question incorrectly. write and find the value of an expression to find lee's final score

The required expression,

Lee's final score is -55.

Step-by-step explanation:

Given,

The current score of Lee = - 350 points,

Now, he answered 275 point question correctly,

∴ Score he gained = + 275 points,

Again he answered 70 point question correctly,

∴ score he gained = + 70

Finally, he answer 50 point question incorrectly,

∴ Score he gained = - 50 points,

So, the total gaining in score = 275 + 70 - 50

Therefore,

Final score = Current score + Gaining scores = -350+275+70-50 = -55

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
