Answer and explanation:
A linear problem is an equation based on known and unknown variables that follow a linear path, usually without exponents and look like this:
y=mx+b. To formulate the linear constraints of the problem above, we look at the unknown variables and known variables and define and equation using this.
From the problem, assume x and y are the prices of the different boat brands:
50x+50y=420000
Assume a and b are number of x brand boats and y brand boats supplied thus:
a+b>=200
Answer:
y = x² + x - 12
Step-by-step explanation:
Given the solutions are x = - 4 and x = 3, then the factors are
x(x - (- 4)) and (x - 3), that is (x + 4) and (x - 3)
The equation is then the product of the factors
y = (x + 4)(x - 3) ← expand using FOIL
= x² - 3x + 4x - 12
= x² + x - 12 ← in standard form
I'm not completely positive but I think it's C
