Answer:
a) line segment
b) point
c) line
Step-by-step explanation:
A line segment is made up of 2 points.
No matter where the lines intersect (doesn't have to be perpendicular), it forms a point.
A line is straight, hence the 3 collinear points.
Answer:
x = 0
y = 4
Step-by-step explanation:
Given
12x - 5y = -20
y = x + 4
Substitute x + 4 for y in the first equation
12x - 5(x + 4) = -20
Expand the bracket
12x -5 X x - 5 x 4 = -20
12x - 5x - 20 = -20
7x - 20 = -20
Add 20 to both sides to eliminate -20 on the left side
7x - 20 + 20 = -20 + 20
7x = 0
Divide both sides by 7 to isolate x
7x/7 = 0/7
x = 0
Substitute 0 for x in either equation to get y
Using equation 2, we have
y = x + 4
= 0 + 4
= 4
x = 0
y = 4
Answer:
True
Step-by-step explanation:
If this is a true or false question it is true.
22 x 20% = 2.2
22 ÷ 10 = 2.2
