Circumference/Diameter = pi = 3.14
C/D = pi = 3.14
Answer:
signs of the constants in the binomial factors are negative
Step-by-step explanation:
Assuming the first term (a) is positive, the fact that c is negative means the constants in the binomial factors have the same sign. The negative b means that sign is negative.
2x^2 -7x +6 = (x -2)(2x -3)

<em>Further comment</em>
c is the product of the constants in the binomial factors so will be positive when both those constants have the same sign.
b is the sum of the constants in the binomial factors. If both factors have the same sign (c > 0), then those constants have the same sign as b.
In this analysis, "a" is assumed to be positive. If it is not, then the same analysis can be done after reversing all of the signs.
M∠NQS = m∠BQS - m∠BQN = 78 - 48 = 30°
Answer:
see attached graph
Step-by-step explanation:
You graphs look fine. The only thing I can think of without seeing the question itself, its that perhaps the teacher wants them on the same graph?
