What is the inverse of the function f(x) = 2x – 10? A. h(x) = 2x - 5B. h(x) = 2x + 5 C. h(x) = 1/2x - 5 D. h(x) = 1/2x - 10
Answers
Answer:
f^-1(x)=1/2x+5
Step-by-step explanation:
y=2x-10
inteechange 'y' with 'x'
x=2y-10
make 'y' the subject
2y=x+10
divide by 2both sides
y=(x+10)÷2
y=1/2x+5
f^-1(x)=1/2x+5

-31/8 converts to -3.875 in decimal form. In the case of negative numbers, 'less than' refers to numbers further from zero. Therefore, -3.92 is 'less than' -31/8.
Explanation:
To answer this question, we first need to convert -31/8 into decimal form. Doing this, we get -3.875.
Now we can compare -3.875 and -3.92. When it comes to negative numbers, a number is 'less' if it is further from zero. In this case, -3.92 is further from zero than -3.875.
So, -31/8 is greater than -3.92. In other words, -3.92 is 'less than' -31/8.
