<u>Given </u><u>:</u><u>-</u>
- A function f(x) = - (x -17)/12
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>
- The inverse of the function .
<u>Solution</u><u> </u><u>:</u><u>-</u>
The given function is ,
f(x) = -(x-17)/12
Replace y with f(x) ,
y = -(x-17)/12
Interchange x and y ,
x = -(y-17)/12
Solve for y ,
12x = -y +17
y = -12x +17
Replace y with f-¹(x) ,
<u>Hence </u><u>the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>-12x </u><u>+</u><u>1</u><u>7</u><u>.</u>
Answer:
2( 3a² - b ² + a) + b(a - 1)
Step-by-step explanation:
I just found like terms, I saw that the ones with numbers in front of the values were a multiple of two, so I bunched them together, and the rest all had the letter b in it, so I bunched them together. hope this helps in some way

Answer:
r = -
Step-by-step explanation:
Given that r varies inversely as t , then the equation relating them is
r = ← k is the constant of variation
To find k use the condition t = - 6 when r = - 2, then
- 2 = ( multiply both sides by - 6 )
12 = k, thus
r = ← equation of variation
when t = - 7, then
r = = -
