Complete 4,5,6 for 25 points.

Step-by-step explanation:

4. A = P + Prt

   a. Solve for r

    Prt = P - A

    r = (P - A)/Pt

    b. Solve for t

         Prt = P - A

           t = (P - A)/Pr

5. Ax + By = C

   a. By = C - Ax

        y = (C - Ax)/B

   b. Ax = C - By

       x = (C - By)/A

6. y = mx + b

   a. mx + b = y

       mx = y - b

       x = (y - b)/m

    b. mx + b = y

        mx = y - b

        m= (y - b)/x

   c. mx + b = y

       b = y - mx

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
