How many solutions does the following equation have? [3x + 12]= 18

A. No solution
B. One solution
C. Two solutions
D. Infinitely many solutions

B. One solution

Step-by-step explanation:

subtract 12 from both sides

subtract 12 from 18

divide each term by 3

divide 6 by 3

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,
