If x = -2, y = 6.
To solve this quesiton, we need to find the value of y if x is equal to -2. We can do this by substiuting the value of x and then solving.
y = 2 (-2) + 10
y = -4 + 10
y = 6
<span>A midpoint divides a line or a segment into two equal parts. If D is the midpoint of the segment AC and C is the midpoint of segment DB, what is the length of the segment AB, if AC = 3 cm.</span>
If D is the midpoint of AC, then AD=DC
If C is the midpoint of DB, then DC=CB
If AC=3cm. then then DC-3/2=1.5
If DC=1.5 then CB is 1.5 also
AB=AC+CB
AB=3+1.5
AB=4.5
Two sides are the same length one angle measures 90 degrees

Answer: inconsistent
Step-by-step explanation:
Inconsistent systems have two lines that are two independent equations that don’t overlap. Basically, if the lines are parallel, the system will always be inconsistent.
