Answer:
C
Step-by-step explanation:
-3 (-1+a)+7 <5
3-3a+7 <5
-3a+10 <5 (collect like terms )
-3a <-10+5
-3a <-5(divide both side by -3)
-3a/-3 <-5/-3
a>5/3

Part b) The graph of the line in the attached figure
Step-by-step explanation:
we know that
A relationship between two variables, t, and d, represent a proportional variation if it can be expressed in the form
or 
step 1
Find the value of k
we have


substitute

so
the linear equation is equal to

step 2
using a graphing tool
graph the line 
Answer:

Step-by-step explanation:
Assume that the shadow of an object in this problem is proportional to the height of the object. One can form the following ratio to describe the objects in this problem,

As per the given problem, a (6) foot person casts a (1.7) foot shadow. Therefore, one can form the following ratio,

It is given that there is a lighthouse that has a shadow of (10.2) feet, one is asked to find its height. Use the parameter (x) to represent the unknown; since the ratios are related, one can form a proportion to solve for(x).
