(2a-7)(a+4)
2a(a) + 2a(4) + (-7)(a) + (-7)(4)
2a^2 + 8a -7a - 28
Combine like terms
2a^2 + a -28

A rational function is any function which can be defined by a rational fraction, which is an algebraic fraction such that both the numerator and the denominator are polynomials
Answer:
y=x and y=2/3x
Step-by-step explanation:
Every point on line a has an equal x and y value so y=x. For line b, the y value of every point is 2/3 of the x value. So at (3,2) 2/3 of 3(the x value) is 2(the y value).
It always cancels out lol
