Answer: sorry sorry sorry sorry I'm doing a competition for who ever reaches 1k points
It does if the x values don't repeat it they repeat it doesn't
Answer:
y=2 x and y=-2x ONE
y=-x - 2 and y = -x - 6 NONE
y = 9x - 1 and y = x + 9 ONE
y = 3x + 4 and 2y = 6x + 8 INFINITE
y=-3 and x = -6 ONE
Explanation:
Any two equations (with y value isolated, meaning y has no coefficient) that have the same slope will have no solutions because they are parallel. Parallel lines never meet. For example:
y=-x - 2 and y = -x - 6
They both have a slope of -1. The slope is the number attached to the "x".
If two equations are equivalent, they will have infinite solutions. Equivalent equations can be found when a whole equation is multiplied or divided by a number. For example:
y = 3x + 4 and 2y = 6x + 8
When you double every term in the first equation, it becomes:
2y = (2)3x + (2)4
It's the same as 2y = 6x + 8
.
Any other case will have one solution.
The answer is 20 millimeters because there is 100 millimeters and to make 10 masks 20 millimeters times 5 is 1 meters and 5 masks
Solution:
We know that:
The wheel was invented about 2500 Before Christ.
The gasoline automobile was invented in AD 1885.
Therefore the number of years passed between the invention of the wheel and the invention of the automobile is:
years
