What is 3x 2y equals 16 in slope intercept form?
If you mean: 3x+2y = 16 then it is y = -1.5x+8
Can anyone solve x plus 2y equals 8 and 3x-2y equals 8 as a simultaneous equation and show their working?
x+2y=8 Here you must add the expressions (2y - 2y = 0) 3x-2y=8 4x=16 Now you are left with a multiple of x so you can simply divide by 4 x=4 on both sides of the = 4+2y=8 Now you substitute x=4 into one of the original equations to find y 2y=4 y=2 Hope this helped.
Slope of 2y equals 6x plus 8?
The slope is 3. --------------------- 2y = 6x +8 /2 /2 /2 y = 3x + 4 Now that it's in y = mx + b form, m = slope, m= 3
What are the solutions for the equations x equals 4y and 3x-2y equals 20?
x = 4y 3x - 2y = 20 Substituting the value of x into the second equation, 3*(4y) - 2y = 20 ie 12y - 2y = 20 or 10y = 20 so that y = 2 Then x = 4y = 4*2 = 8. So (x , y) = (8 , 2)
What does x equals in 3x plus 11 plus 5x equals 75?
3x+11+5x=75(add 5x and 3x) 8x+11=75(-11) 8x=64(/ 8) x=8(ANSWER)
Is 3x plus 2y equals 8 a quadratic function?
3x + 2y = 8 2y=8-3x y=4-1.5x A quadratic has x^2 This is the equation of a line with negative slope.
Is 2y equals 6x plus 8 the same as y equals 3x plus 6?
Well lets see: 2y = 6x+8 y=3x+4 does not equal y=3x+6 So they are not the same.
3x plus 2y equals 2 and -2x plus y equals 8?
(-2, 4)
What is equation of 3x plus 2y equals 8 and 5x plus 2y equals 12?
Both of them are equations!The solution is (x, y) = (2, 1).
3x plus 2y equals 20 and 5x-2y equals 1?
3x+2y=20 5x-2y=1 (3x+2y) + (5x-2y)= 20+1 3x+5x= 21....... 8x=21.........x=2 5/8 Subsitute x=3(2 5/8)+ 2y=20........... 7 7/8 +2y=20.........2y= 20- 7 7/8....... y=6 1/16
X plus 2y equals 8 3x - 4y equals 10?
Multiply the first equation by -3
-3x plus 2y equals 8 in slope intercept form?
-3x + 2y = 8To get into slope intercept, we must set the equation equal to y2y = 3x + 8y = 3/2x + 8/2y = 3/2x + 4
What is 3x 2y equals 16 in slope intercept form?
If you mean: 3x+2y = 16 then it is y = -1.5x+8
What are x and y in the equation 3x plus 2y equals 2 -2 plus y equals 8?
The values are: x = -6 and y = 10
What are the solutions to the simultaneous equation 3x plus 2y equals 5 and x plus 2y equals 7?
3x + 2y = 5x + 2y = 7Subtract (2) from (1) to give: 3x - x + 2y - 2y = 5 - 7→ 2x = -2→ x = -1Substitute for x in (1)3(-1) + 2y = 5→ -3 + 2y = 5→ 2y = 8→ y = 4Substitute for x and y in (2) to check answer:x + 2y = -1 +2(4) = -1 + 8 = 7 as required. Thus:x = -1y = 4
Solve for X and Y using the addition method 3X plus 2Y equals 4 X-Y equals 8?
3x + 2y = 4; 2x - 2y = 16 Add; 5x = 20 so x = 4 and y is therefore -4
X equals 4y and 3x - 2y equals 20?
(8, 2)
