Evaluate 2ac plus 3bc minus abc when a is equal 2 and b equal 2 and c equal 4​

24

Step-by-step explanation:

The algebraic expression is:

2ac + 3bc - abc

a = 2, b = 2, c = 4

2ac + 3bc - abc = 2(2)(4) + 3(2)(4) - (2)(2)(4) = 16 + 24 - 16 = 24

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
