If it is 4 1/2, you can make 10 four and a half inch strips with no remainder
For polynomials, if we say of "rate of change", we are talking about the slope of the tangent line. That is the value of dy/dx or the differential of y in terms of x. From the given choices, the answer would be the second choice, y = 19x - 10. This is because dy/dx in this item is essentially equal to 19 which is a constant.
I am pretty sure the answer would be (a)
6/30 = 1/5
This means that 1/5 of the students in a class will be left-handed.
27*5 = 135
27/135 = 1/5
The correct answer is 135 students.
