Answer:
Step-by-step explanation:
-1/4 the negative reciprocal of the slope of the red line
Answer:
80/3
Step-by-step explanation:
7 = (3x + 4)/12
84 = 3x + 4
84 - 4 =3x
80/3 = x
x = 80/3
Answer:
Infinitely many solution.
Step-by-step explanation:
The given system is
x = y + 4
y = x - 4
To graph the first equation, we write it in slope-intercept form to get: to
x=y+4
This implies y=x-4.
This has a slope of 1 and a y-intercept of -4.
The graph of this function is shown in the attachment.
The second equation is y=x-4.
This equation is identical to first equation, so its graph coincides with the first one.
The system has infinitely many solution.
