D varies directly with t means
d=kt
105=3k
divide both sids by 3
35=k
d=35t
when t=8
d=35(8)
d=280
B
361 + 173 =361+173
(a+b)+(a-b)=361+173
a+b=a-b=534
2a=534
a=267
267+b=361
b=94
the two numbers are 267 and 94

Answer:
if you re not listening,you won,t understand the lesson
If I understand right you want the inverse of H(x)
H(x)=x
y=x
to calculate the inverse, isolate x, which is already the case, switch x and y, which doesn't change anything and that is your new function
the inverse is the same function in this case
so H⁻¹(x)=x
