4y engine cc Question 1074903: Find the foci of \ [3x^2 + 2y^2 + 6x - 4y + 5 = 18. In 4y-4y, if you plug in 1, you get: It is the same with any number. You can put this solution on YOUR website! x=16-4y 3x+4y=8 Pretty simple. Therefore, 4y-4y has to be 0. 7x 4y = 4 Answer by funmath (2933) (Show Source): Question 1074903: Find the foci of \ [3x^2 + 2y^2 + 6x - 4y + 5 = 18. Answer by Boreal (15235) (Show Source): You can put this solution on YOUR website! x - 4y = -24 m= b= Your "target" is the slope-intercept form which you should memorize: You first solve the equation for y Subtract x from both sides: To get rid of the multiply every term by Simplify: Swap the terms on the right because you want it to look like y = mx+b Compare that to And you see that and "m" is the slope because it determines which You can put this solution on YOUR website! Start with the given equation Subtract from both sides Rearrange the equation Divide both sides by Break up the fraction Reduce Looking at we can see that the equation is in slope-intercept form where the slope is and the y-intercept is Since this tells us that the y-intercept is . You can put this solution on YOUR website! Remember, the "slope-intercept" form is: y = mx + b where m is the slope b is the y-intercept at (0,b) . It solves most middle school algebra equations and simplifies expressions, and it SHOWS ALL WORK. 3x+4y=8 -3x -3x ; Minus 3x by both sides, it then becomes -3x but on the other side: ---------- 4y=-3x+8 - ----- 4 4 ; Divide 4 by both sides so y is by itself, divide 4 by mx+b ---------- y=- x+2 ; Since -3 doesn't go into 4 evenly, then it . A good way to check if an answer is correct is by plugging in a random number to see if you get the same result. 3x+4y=-16 Found 2 solutions by jim_thompson5910, stanbon: You can put this solution on YOUR website! Start with the given equation Subtract from both sides Rearrange the equation Divide both sides by Break up the fraction Reduce Looking at we can see that the equation is in slope-intercept form where the slope is and the y-intercept is Since this tells us that the y-intercept is . Remember the y-intercept is the point where the graph intersects with You can put this solution on YOUR website! Remember, the "slope-intercept" form is: y = mx + b where m is the slope b is the y-intercept at (0,b) . Remember the y-intercept is the point where the graph intersects with Question 177165: Graph the line. 4y and 4y are the same number no matter what you substitute in for y. So, for your problem, we start by manipulating it into the "slope-intercept" form: 3x + 4y = 8 subtract 3x from both sides: 4y = -3x + 8 dividing both sides by 4: y = (-3/4)x + 2 Which is the FIRST solution given. 7x 4y = 4 Answer by funmath (2933) (Show Source): You can put this solution on YOUR website! x - 4y = -24 m= b= Your "target" is the slope-intercept form which you should memorize: You first solve the equation for y Subtract x from both sides: To get rid of the multiply every term by Simplify: Swap the terms on the right because you want it to look like y = mx+b Compare that to And you see that and "m" is the slope because it determines which Question 915113: find the value of x if y=8 in the equation: 2x + 4y = 50 Found 2 solutions by jim_thompson5910, tonyclarke: Question 177165: Graph the line. 3x+4y=8 -3x -3x ; Minus 3x by both sides, it then becomes -3x but on the other side: ---------- 4y=-3x+8 - ----- 4 4 ; Divide 4 by both sides so y is by itself, divide 4 by mx+b ---------- y=- x+2 ; Since -3 doesn't go into 4 evenly, then it Welcome to Graphical Universal Mathematical Expression Simplifier and Algebra Solver (GUMESS). A good way to check if an answer is correct is by plugging in a random number to see if you get the same result. \] Enter your answer as a list of pairs separated by commas. x=16-4y is already in mx+b form. Any number minus itself is always zero. It is free to use. 3x+4y=-16 Found 2 solutions by jim_thompson5910, stanbon: Question 915113: find the value of x if y=8 in the equation: 2x + 4y = 50 Found 2 solutions by jim_thompson5910, tonyclarke: Welcome to Graphical Universal Mathematical Expression Simplifier and Algebra Solver (GUMESS). Question 72985: Find the slope and y-intercept. I will figure out if what you typed is an equation. Enter expression to be simplified, or equation to be solved. 3x+4y=8 -3x -3x ; Minus 3x by both sides, it then becomes -3x but on the other side: ---------- 4y=-3x+8 - ----- 4 4 ; Divide 4 by both sides so y is by itself, divide 4 by mx+b ---------- y=- x+2 ; Since -3 doesn't go into 4 evenly, then it A good way to check if an answer is correct is by plugging in a random number to see if you get the same result. You'll need to get the other in mx+b form. Answer by Boreal (15235) (Show Source): Question 72985: Find the slope and y-intercept.
