Answer:
Step-by-step explanation:
so its 36+9 = 45
36/45=4/5

For a system of 2 equations in 2 unknowns, there are 3 cases:
- slopes are different — one solution
- slopes are the same and y-intercepts are different — no solutions
- slopes and y-intercepts are the same — infinitely many solutions
When slopes are different, the two lines intersect at <em>one</em> point, the <em>solution</em>.
When slopes are the same, the lines may be either parallel (different y-intercepts) or the same (same y-intercepts). If the lines are parallel, there are no points of intersection, hence <em>no solutions</em>. If the lines are the same line, they intersect at all points, so there are <em>infinitely many solutions</em>.
If you type the equation into y1 on your calculator and use the table graph you get coordinates that you can graph. ( 0,-9 ) ( 1,-6 ) ( 2, -3 ) ( 3 , 0 ) ( 4, 3 ) ( 5 , 6 ) ( 6 , 9 ), just graph those and that should answer your question :)
Answer:
y = 24
Step-by-step explanation:
y - x = 13
x = 11
y - 11 = 13
y = 13 + 11 = 24
Answer:
I folded a chainring on my bike so instead of a circle it was more parabolic and it was semi symetric due to the amount of teeth on each side of it.
