The system of equations graphed below has how many solutions ?
2 answers:
Answer:
Option A. 0 solutions.
Step-by-step explanation:
The system of equations graphed has two equations.
and
Here equation 1 and 2 both have the same slope = -3/2
Therefore these lines are parallel.
Since parallel lines never meet at a point so the solutions of this systems of the equations will be zero.
Option A. 0 is the correct option.

Answer:
m∠y=72°
Step-by-step explanation:
<u><em>The question is</em></u>
Find the measure of angle y
step 1
Find the measure of angle x
see the attached figure to better understand the problem
we know that
m∠x=67° -----> by corresponding angles
step 2
Find the measure of angle y
we know that
(m∠x+m∠y)+42°=180° -----> because form a straight line
substitute the measure of angle x
67°+m∠y+42°=180
m∠y+108°=180
m∠y=180°-108°
m∠y=72°
