The number line shows the distance in meters of two skydivers, a and b, from a third skydiver located at point x:
a = -2.5
b = 0.5
x = 0

write an expression using subtraction to find the distance between skydivers a and b. (5 points)
show your work and solve for the distance using additive inverses. (5 points)

the answer is 62

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

answer: they are supplementary angles
