On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite direction. The number b varies directly with the number a. For example b = 2 when a = –2. Which equation represents this direct variation between a and b?
Answers
Answer:
The equation is b = -a
Step-by-step explanation:
Given,
The number b varies directly with the number a,
That is, we can write,
b ∝ a
⇒ b = ka
Where k is the constant of proportionality,
Given, if b = 2 then a = -2,
By substituting the value,
2 = k(-2)
⇒ k = -1
Hence, the equation that represents the direct variation between a and b is,
b = -a

Answers
The correct answer is:
300° – 720°
Explanation:
Coterminal angles are angles that, when drawn in standard position, have terminal sides in the same place.
Any angles that are coterminal are some multiple of 360° different in measure. This is because in order to be coterminal, they must travel the entire circle at least once, possibly more times.
Out of the given options, the only one that is a multiple of 360° is 300° – 720° .

A team's run differential is determined by subtracting the total number of runs (both earned and unearned) it has allowed from the number of runs it has scored.
Step-by-step explanation:
In baseball, run differential is a cumulative team statistic that combines offensive and defensive scoring. Run differential is calculated by subtracting runs allowed from runs scored. Run differential is positive when a team scores more runs than it allows; it is negative when a team allows more runs than it scores.
