Question

How many solutions does this system have?
4x + 16y = 12 ; y = -1/4x + 9/12

a) one
b) two
c) infinitely many
d) none

Answer 1

c) infinitely many

Answer 2

well what kind of lines do they make?

Answer 3

how do you know?

Answer 4

first of all
a solution to the system means an intersection

Answer 5

parallel lines
will they have an intersection?

Answer 6

no

Answer 7

Since both equation are not different...If you rearrange 1st equation you get the second one...

Answer 8

Follow mth3v4.

Answer 9

therefore no solution
next
if they have the
same y intercept
and same slope

Answer 10

so the answer would be B?

Answer 11

Those two equations are parallel lines. They will not intersect. Therefore, no solution.

Answer 12

:)

Answer 13

Answer is d).

Answer 14

to get to you answer
you will have to put the equations in
slope intercept form ( or unless you can see it straight out)
