Answer 1

@Nnesha

Answer 2

I got it its b

Answer 3

can you answer the question iclosed idk it

Answer 4

Given the equation 4x + 2y = 9, which equation below would cause an inconsistent-independent system?

6x + 12y = 13
2x + y = -6
x - 2y = 7
8x - 4y = -5

Answer 5

same slope, different y intercepts -- no solutions because they are parallel.
same slope, same y intercept -- infinite solutions because they are the same line
different slopes, different y intercepts -- 1 solution

Do you know how to find the slopes and y intercepts of these equations ?

Answer 6

its the 3.5x

Answer 7

Idk how to do anything on the second question

Answer 8

y = mx + b form...the slope is in the m position and the y intercept is in the b position.
y = 3.5x - 3.5 --- slope is 3.5 and y int is -3.5
y = -3.5x + 3.5 -- slope is -3.5 and y intercept is 3.5

the slopes are different and the y intercepts are different (because of the signs).
Therefore, there is only one solution

Answer 9

so its one solution? and whats the second question this one Given the equation 4x + 2y = 9, which equation below would cause an inconsistent-independent system?

6x + 12y = 13
2x + y = -6
x - 2y = 7
8x - 4y = -5

Answer 10

I did this one earlier...but it confuses me because I do not see how a set of equations can be inconsistent and independent.
I do know that 2x + y = -6 would cause an inconsistent equation because the slopes of the lines are the same and the y intercepts are different...meaning parallel lines and inconsistent

Answer 11

so its 2x+y=-6?

Answer 12

That would cause an inconsistent set of equations...so I think so
