SOLUTION: Graph the line: 3x + 4y =12 Algebra -> Graphs -> SOLUTION: Graph the line: 3x + 4y =12 Log On Algebra: Graphs, graphing equations and inequalities Section

3x - 12 = 15 Add 12 to each side of the equation. 3x - 12 + 12 = 15 + 12 Combine like terms: -12 + 12 = 0 15 + 12 = 27 Therefore: 3x = 27 Divide each side by 3 3x/3 = 27/3 x = 9 Answer: x = 9 Lennox Obuong Algebra Tutor Nairobi, Kenya Email: [email protected]

2. Substitute 2y + 8 for x in the other equation 3x - 2y = 12. Solve for y. 3(2y +8) - 2y = 12 , Use Distributive Property to simplyfy this. 6y + 24 - 2y = 12 , Combine like terms. 4y = -12 , Divide both sides by 4 to solve for y. 3. Substitute the result from step 2 in either equation. Solve for the other variable. You can use either of the ...

3x^2-5x -12 = 0----(1) 3x^2+(-9x+4x)-12 = 0 (splitting the middle term as the sum of two terms in such a way that these two when multiplied(of course along with the signs)should give the product of the square term and the constant term.)

You can put this solution on YOUR website! 4y=3x+12: y=(3/4)x+3: slope is 3/4, y intercept is 3: make a table for any given value of x find y and then plot those point and you will end up with this line

Question 764499: the function f(x) = x^2 + 6x +20 + k(x^2 -3x -12) where k is real find the value of k and the value of p given that the minimum value of f(x) is p and that f(-2) =p the answers are 2/7 anf 80/7 i am happy if you just explain to me what to do, even briefly.

-2y=3x+12 y=3x/-2+12/-2 y=-3x/2-6 (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, -3x/2 -6).

3x-2y=12 Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website ...

3x+12 = 212-7x Add 7x to both sides. 10x+12 = 212 Subtract 12 from both sides. 10x = 200 Divide both sides ...
