On a winter day, the low temperature in Anchorage was 23 degrees below zero (in ∘C ) and the low temperature in Minneapolis was 14 degrees below zero (in ∘C ). Sophia wrote: Minneapolis was colder because −14 < −23. Is Sophia correct? Explain your answer.

Sophia is Incorrect

Step-by-step explanation:

23 degrees lower than 0 = -23 degrees

14 degrees lower than 0 = -14 degrees

-23 is less than -14 because it is farther to the left on the numberline than 0. This means Sophia is incorrect because she wrote that -14 is less than -23 (-14 > -23), the correct answer is -14 is greater than -23 (-23<-14)

Please tell me if I'm wrong :)

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,

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
