You will need to convert them into improper fractions, subtract them, and convert them back to mixed numbers.
5 1/8 - 2 4/8
41/8 - 20/8
21/8
2 5/8
Your answer is 2 5/8.
Answer: 32.2
Step-by-step explanation:
F(x) = 3x + 1
let f(x) = y
y = 3x + 1
y - 1 = 3x
3x = y - 1
x = (y - 1)/3
From y = f(x), x = f⁻¹(y)
<span>x = (y - 1)/3
</span>
f⁻¹(y) = (y - 1)/3
f⁻¹(7) = <span>(7 - 1)/3 = 6/3 = 2
</span>f⁻¹(7)<span> = 2</span>
D
Remember starts at zero slope is up 4 right 1
Y= 4/1x+0
Y=4x
