Answer:
See attachment
Step-by-step explanation:
The given system is
2x-y=4
x-y=-2
We write the system in slope-intercept form:
y=2x-4
y=x+2
The first equation has slope of 2 and y-intercept at (0,-4)
When y=0, x=2.
We plot (0,-4) and (2,0) to graph this first equation.
The second equation has a slope of 1 and a y-intercept at (0,2)
Also when y=0, x=-2.
We plot (0,2) and (-2,0) and draw a straight line through them.
The graph of the system is shown in the attachment.
Answer:
32 sq. ft.
Step-by-step explanation:
1/2 (8x8)=1/2(64)=32
Answer:
C
Step-by-step explanation:
The trig equation

where d represent the midline.
D is represented by positive 1 so y=1 is the midline.
Speed of the jet = 460/2 miles/hour = 230 miles/hour.
In 9 hours, the jet can fly = 9×230 miles = 2070 miles.
