One possible system is
1x + 3y = 4
2x + 6y = 8
Note how 2 is twice as large as 1, 6 is twice as large as 3, and 8 is twice as large as 4.
In other words, the second equation is the result of multiplying both sides of the first equation by 2.
1x+3y = 4
2*(1x+3y) = 2*4
2x+6y = 8
Effectively the two equations in bold are the same which produces the same line. The two lines overlap perfectly to intersect infinitely many times. An intersection is a solution.

Answer:2.38782608695652173913043478260869565217
Step-by-step explanation:
you divide 1373 by 575
Answer:
B
Step-by-step explanation:
The equation is in slope-intercept form, so the slope is the coefficient of x. Since the coefficient of x is negative, so is the slope.
Answer:
1. b = 36 2. b = 42
Step-by-step explanation:
In diagram one, there is a right angle
90 - 54 = 36
b = 36
In diagram two, you can discern an angle of 180 degrees
180 - 138 = 42
b = 42
