Answer:
f-¹(x) =(1-5x) /3x.
Step-by-step explanation:
f(x)=1/(3x+5)
Let y=1/(3x+5)
Exchanging x and y,
x=1/(3y+5)
3y+1=1/x
3y=1/x-5
3y=(1-5x) /x
y=(1-5x)/3x
f-¹(x) =(1-5x) /3x.
$27.50/11 = $2.5
2.5 x $4 = $10
Travis would pay $10 for 4lbs of grapes
Well 12 = 3×4 thus answer would be -3 and -4
For algebra solution, we can let smallest integer be n then that would be n(n+1) = 12, so we can go ahead and solve for n:
n(n+1) = 12
n² + n - 12 = 0
(n-3)(n+4) = 0
n = 3 or -4
Since we need negative integers, n would be -4 and then next integer (n+1) would be -3.
Hope this helps.
