What is the value of x in the following? 40x + 7=2x × 12 - 16

x = -1.4375

Step-by-step explanation:

Multiply the monomials: 40x + 7 = 24x - 16

Rearrange unknown terms to the left side of the equation: 40x-24x=-16-7

Combine like terms: 16x=-16-7

Calculate the sum or difference: 16x = -23

Divide both sides of the equation by the coefficient of variable: x = -23÷16

Calculate the product or quotient: x=-1.4375

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,
