Step-by-step explanation:
it is a simple addition and subtraction sequence :
10 + 0 + -21 + 14 = 3
since the result is positive, it is overall a gain.
if the result were negative, it would be an overall loss.
so, he had an overall gain of 3 yards.
Answer:
2
Step-by-step explanation:
In situations such as this one, why not look up the technical vocabulary, so that you can be sure of its meaning? I did that and found that my recollection of "inconsistent equations" was correct.
TRUE.
Not necessarily, the more correct definition is opposite reciprocal slopes.
The example used is how horizontal and vertical lines are parallel. Horizontal lines have a slope of 0, also written as 0/1. However, vertical lines have an undefined slope, which isn't necessarily negative. It has a slope of 1/0, which is undefined. In this case, the reciprocal isn't negative.
In all other cases (1 and -1, 2 and -1/2, etc.) yes, the perpendicular pairs are negative and reciprocal.
