Answer:

-21

Step-by-step explanation:

Since 3t - 7 = 5t,

=> 3t - 7 - 3t = 5t - 3t

               -7 = 2t

                t = -3.5

Therefore, 6t = (-3.5) * (6) = -21

Done :)

Answer:  16) \bold{\sqrt{x}}        (17) \bold{\dfrac{x-4}{2}}        (18) \bold{\sqrt{x}-2}       (19)  3x - 18

<u>Step-by-step explanation:</u>

Inverse is when you swap the x's and y's and then solve for y

16) Given: y = x²

Swapped: x = y²

                \bold{\sqrt{x} =y}

17) Given:  y = 2x + 4

Swapped: x = 2y + 4

            x - 4 = 2y

            \bold{\dfrac{x-4}{2}=y}

18) Given:  y = (x + 2)²

Swapped: x = (y + 2)²

               √x = y + 2

        \bold{\sqrt{x}-2=y}

19) Given:  y=\dfrac{1}{3}x+6

Swapped: x=\dfrac{1}{3}y+6

            x - 6 = \dfrac{1}{3}y

            3(x - 6) = y

            3x - 18 = y
