Points C, D, and E are collinear on CE, and CD:DE = 3/5. C is located at (1,8), D is located at (4, 5), and E is located at (x, y). What are the values of x and y? Answer choices are :
A. (12,-1)
B. (9,0)
C. (0,9)
D. (-1,12)

y -5 = (-1/4)(x + 8)

step-by-step explanation:

you need to give us more information since we can't answer

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
