First of all this question is awesome.
second 317 x 25 = 7925
Be sure to give me a thanks and rate me 5 stars :D
<span>A system of equations has infinitely many solutions when the two
lines representing the equations coincide. i.e. the two equations are
the same or a multiple of each other.
2y - 4x = 6
2y = 4x + 6
2y = 2(2x + 3)
y = 2x + 3
-y = -(2x + 3)
-y = -2x - 3
Hence the other equation is -y = -2x - 3</span>
Answer and explanation:

(x + 6)(x + 7)
List the multiples of 42
42: 1 2 3 6 7 14 21 42
Then see which of the multiples add up to 13
1 x 42 = 42 --> 1 + 42
13
2 x 21 = 42 --> 2 + 21
13
3 x 14 = 42 --> 3 + 14
13
6 x 7 = 42 --> 6 + 7 = 13
Answer:
<h2>NONE OF THEM</h2>
Step-by-step explanation:
From the graph,
y and x intercepts are
and approximately
respectively
for A, C and D : 
x intercept the value of y=0, and y intercept x=0.
x and y intercepts are
and approximately
respectively
for B: 
x and y intercepts are
and approximately
respectively
Therefore x and y intercepts for the lines
and
they are not equal to the x and y intercepts of the given graph
