Inverse equation t=120r/r+120 R=???

Komok [63]

9514 1404 393

Answer:

r = 120t/(120-t)

Step-by-step explanation:

Multiply by the denominator, isolate r terms, then divide by the coefficient of r.

$t=\dfrac{120r}{r+120}\qquad\text{given}\\\\t(r+120)=120r\qquad\text{multiply by $(r+120)$}\\\\120t=120r-tr\qquad\text{subtract $tr$}\\\\\dfrac{120t}{120-t}=r\qquad\text{divide by the coefficient of $r$}\\\\\boxed{r=\dfrac{120t}{120-t}}$

Use the Line Tool to graph the equation. 2x−7y=14

kirza4 [7]

Convert to Y=MX+B to make it easier, minus 2x from both sides to get -7y=-2x+14, then divide it all by -7 to get y=2/7x-2. 2 equals your starting point, from there go down 2 and over 7 for you slope and repeat until the graph is done.

Gina wants to ride the waves at flagship pier in Galveston so she rents a surfboard for 5$ per hour plus an initial or beginning

Aneli [31]

If Gina has $90 and pays:

$20 for beginning
$5 per hour

Then 90 - 20 is 70. 70 divided by 5 is 14.

She can rent a surfboard to surf for 14 hours.
