D
Step-by-step explanation:
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
y-x> 0 -----> inequality A
y> x
The solution of the inequality A is the shaded area above the dashed line y=x
x+1<0 ----> inequality B
x < -1
The solution of the inequality B is the shaded area at the left of the dashed line x=-1 (open circle)
therefore
The solution of the system of inequalities in the attached figure
ANSWER
A) For all x > 0 the graph will be higher.
EXPLANATION
Jack's graph has equation
y=2x
This graph passes through the origin and has slope 2.
Nina's graph is y=5x.
This graph also passes through the origin and has slope 5.
Since 5 is greater than 2, for all x>0, Nina's graph will be higher.
