I think is...
A=Andrews class
L=Laurens class
L-3=A
So, Laurens class has 3 less students than Andrews class.
Point -slope form of a straight:
we have a point (x₀,y₀) and the slope m.
y-y₀=m(x-x₀)
Given two points (x₁,y₁) and (x₂,y₂) the slope will be:
m=(y₂-y₁)/( x₂-x₁) or m=(y₁-y₂)/(x₁-x₂)
In this case:
(2,3)
(4,4)
m=(4-3) / (4-2)=1/2
we can choose the point (2,3) or the point (4,4); the result will be the same.
y-y₀=m(x-x₀)
y-4=1/2(x-4)
y=1/2 x-2+4
y=1/2 x + 2
Answer: the funciton passes through the poinsts (2,3) and (4,4) is:
y=1/2 x+2
On this problem, just use the information you know. So...
Kimtoya rides at a rate of 12.5 kilo. per hour and Sidney rides at a rate of 12.5 kilo. per hour. Kimtoya's rate of speed is equal to Sidney's rate of speed.
(You get Sidney's rate of speed by dividing the x and y from the table, 2 and 25 which gets you to 12.5.)

Answer:
2 complex roots
Step-by-step explanation:
The function f(x)=x^5+4x^3−5x can be factored as follows:
f(x)=x(x^4+4x^2−5). One root, a real root, is zero.
That leaves g(x) = x^4+4x^2−5. Substitute p = x^2, obtaining p^2 + 4p - 5 = 0. This factors as follows: (p+5)(p-1) = 0. Thus, p = -5 and p = 1.
Recalling that p = x^2, we have -5 = x^2 and +1 = x^2. The latter yields x = 1 and x = -1. The former yields +i√5 and =i√5.
Thus, the given poly has 3 real zeros: -1, 1 and 0. Due to the imaginary roots shown above, this means that this poly has 2 complex roots.
