Answer:
148/100=37/25
Step-by-step explanation:
Who have to think how many zeros it took for the decimal to get between the 1 and 4.
148/100=37/25 is your answer.
Answer:
-2.4-(-7) has the same result as -2+7 because the negative sign and the minus sign cancel each other out. Think of it like this. If you cross the negative sign and the minus sign together, then it makes a plus sign.

I gave a basic answer. You might have to elaborate more on this.
Answer:
168
Step-by-step explanation:
f(x) = 4x + 3
That's one-to-one, a linear function that will give a different f(x) for each different x.
For the inverse let's swap x and y and solve for y
x = 4y + 3
x - 3 = 4y
y = (x- 3)/4
That's the inverse,
Answer: (x- 3)/4, second choice
The domain and range of the inverse is all real numbers. It's two lines; I'll leave the graphing to you.
