Answer:
The numbers which are 1.4 units from −3.2 on a number line are:
a. -4.6
c. -1.8
Step-by-step explanation:
We are asked to find the points which are:
1.4 units from −3.2 on a number line.
i.e. the number may lie at a distance of 1.4 units from -3.2 i.e. it may be 1.4 units to the right or to the left of -3.2.
i.e. we get:
|-3.2-x|=1.4
i.e.
-3.2-x=1.4 or -3.2-x= -1.4
i.e.
x= -3.2-1.4 or x=-3.2+1.4
i.e.
x= -4.6 or x= -1.8
