Answer:
see below
Step-by-step explanation:
It is easiest to compare the equations when they are written in the same form.
The first set can be written in slope-intercept form.
y = 2x +7
y = 2x +7 . . . . add 2x
These equations are <em>identical</em>, so have infinitely many solutions.
__
The second set can be written in standard form.
y +4x = -5
y +4x = -10
These equations <em>differ only in their constant</em>, so have no solutions.
__
The third set is already written in slope-intercept form. The equations have <em>different slopes</em>, so have exactly one solution.

<em>Question:</em>
<em>The digit 8 in which number represents a value of 8 thousandths?
</em>
Answer:
See Explanation
Step-by-step explanation:
The question requires options and the options are missing.
However, the following explanation will guide you
Start by representing 8 thousandths as a digit

i.e.
8 thousandths implies 0.008
Next;
Replace the 0s with dashes
_ . _ _8
Note that there are two dashes after the decimal point and before 8
PS: The dashes are used to represent digits
This implies that thousandths is the 3rd digit after the decimal point
Typical examples to back up this explanation are:
<em>17.008, 1.1489, 0.008 and so on...</em>
120/100 = x/15
100x = 1800 (Divide by 100 on both sides)
x = 18
