Find the slope between the points ( -2, -6) and (3, 14)

4

Step-by-step explanation:

Slope equation:

y1 = -6

y2 = 14

x1 = -2

x2 = 3

y2-y1 = 14 - (-6) = 20

x2-x1 = 3 - (-2) = 5

20/5 = 4

what are the statments

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
