Answer: A
Step-by-step explanation:
In mathematics, a scale can be described in charts as a marking system at predefined times, which determines the relationship between the units that are being used and their images on the graph, and the further calculation can be defined as follows:
- Since in this question, the ratio is between 3 cm to 4 km you can make a
split, and if you are split between 3 and 4, you get the ratio between
.

Therefore the final answer is "0.75 cm to 1 km"

Answer:
The correct linear equation is;
f(x) = 10x + 8
Step-by-step explanation:
To choose the correct linear function, we just need to take a specific point, then substitute in each of the equations given to get the one right
The correct one will be the one in which when the x-value is substituted, we will get the y-value
Let us pick (1,18)
Let us begin testing;
A. f(x) = 10x + 8
f(1) = 10(1) + 8 = 10 + 8 = 18
Let us use another point to test this
The second point is (1.5,23)
f(1.5) = 10(1.5) + 8
= 15 + 8 = 23
