Lines 2 and four r perpendicular I think
Answer:
This can be solved like this:
4x-3x+9=20
<em>Solving 4x-3x</em>
x+9=20
Transposing +9
x=20-9
And now we have, x=11
The following inequality shown is 2) because the y-intercept is at 1/2 and the slope is negative. The graph is also shaded underneath so must include the values underneath the function
Another number that could be in the pattern is the number 8
