A mapping system is a way of describing
a C. Preimage of a figure. Mapping statements are known to define the range of
data sources thus showing all the data. While on the other hand, preimage (in
Mathematics) meaning is that set of all the elements of the domain that maps to
the members of S.

Okay so because we are talking about the rate of km per hour. This means that car A is going 208km per hour. We are trying to find out how many km at 12 hours so we are going to multiply:
208x12= 2496km
Now we have to do the same for car B:
215x12= 2580km
Next we have to figure out how many km more did car B drive than car A so we have to subtract:
2580-2496= 84km
Hope this helps(;
Answer:
<em>Question 7. Option B,</em>
<em>Question 8. Option C</em>
Step-by-step explanation:
<em>Question 7.</em>
Let us create a proportionality, and solve for the value of s, through cross multiplication;

<em>Question 8.</em>
We can solve this problem in a similar manner, through setting a proportionality and solving for the length of the shadow of the tree, which we can pose as x;

2+2a 1x4a
