Answer:
A system of linear equations is just a set of two or more linear equations. In two variables (x and y) , the graph of a system of two equations is a pair of lines in the plane.
Step-by-step explanation:
The lines intersect at infinitely many points. (The two equations represent the same line.)

Answer:
bottom graph
Step-by-step explanation:
f(x) = |3q-6|
because you have absolute value there are 2 possibilities
y= +(3q-6) and y= -(3q-6)
to find where the graph intersects the x-axis make y=0 because there the y coordinate is 0, so we have...
3q-6 =0 and -3q+6 =0
3q= 6 and -3q =-6
q=2 and q=2
the bottom graph has the intersection with x-axis only at 2, so is the correct one
Answer:
202m
Step-by-step explanation:
Complete question
(A zip line starts on a platform that is 40 meters above the ground. The anchor for the zip line is 198 horizontal meters from the base of the platform.
How long is the zip line? See attached diagram for illustration)
Using pythagoras theory
Y = 40
Z = 198
X =?
X² = y² + z²
X² = 40² + 198²
X² = 40804
X = 202m
The zip line is 202m
Answer:
A) 12x-4y
Step-by-step explanation:
Since a square has a perimeter of P=4s, then P=4(3x-y)=12x-4y, therefore A is the correct option.
