Dea writes the expression 0.25 + 0.76 + 0.75 + 0.24. She rewrites the expression using the commutative property. Which expression could Dea have written using the commutative property?

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

a - base

b - exponent

so,

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,

66.666666667%

step-by-step explanation:

divide 150 by 100

divide 100 by 1.5

there you go!
