4b+20 because you disrepute the 4
Answer:
.2 lbs
Step-by-step explanation:
4.5/22.5
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
Change in x is 4, multiply that by slope, which is rise/run so you displace the y value by -3*4 or -12
t = -9
