Step-by-step explanation:
1 divided by 138 is roughly .7%. Run it through a calculator, then convert the decimal
The function would be f (x) = 0.4x - 4.
Explanation
We can see that this is linear, since it increases at a constant rate. We find the slope using the formula
m=(y₂-y₁)/(x₂-x₁) = (0.8-0.4)/(12-11) = 0.4/1 = 0.4
We use point-slope form to write the initial equation:
y-y₁ = m(x-x₁)
y-0.4 = 0.4(x-11)
Using the distributive property:
y-0.4 = 0.4*x - 0.4*11
y-0.4 = 0.4x-4.4
Add 0.4 to both sides:
y-0.4+0.4 = 0.4x-4.4+0.4
y=0.4x-4
Answer:
9:45am.
Step-by-step explanation:
In 6 Hours and 20 minutes, there's 380 minutes.
Because 60 x 6 + 20 =380
So you go back 380 minutes from 4:05.
4:05pm minus 380minutes= 9:45am.
