What is 2x plus 3y minus 2 plus3x plus 6y plus 7?
It is an algebraic expression that can be simplified to: 5x+9y+5
What is 5x-9y equals 7 7y-3x equals -5?
If: 5x-9y = 7 and 7y-3x = -5 Then: x = 1/2 or 0.5 and y = -1/2 or -0.5
What is the slope of any line parallel to the line formed by the equation 45x plus 9y equals 36?
The slope of any line parallel to the line described is -5. Solution: 45x+9y=36. Solve for y. 9y=36-45x. y= -5x+4 m=-5
9y plus 5 equals 0 what is y?
9y + 5 = 0 (-5 on both sides)9y = -5 (/9 on both sides)y = -5/9
How do you find graph cordinates in this problem 5x-9y equals 43 3x plus 8Y equals 68?
5x - 9y = 43 (A)3x + 8y = 68 (B)(A)*3: 15x - 27y = 129(B)*5: 15x + 40y = 340Subtracting the first from the second gives67y = 211 => y = 211/67 = 3.15 approxSubstituting the [rational] value of y in (B)5x - 9*211/67 = 43 => 5x = 43 + 1899/67 = 4780/67therefore x = 956/67 = 14.27 approx.
What is the slope-intercept form of 5x plus 9y equals -36?
Slope-intercept form is y = mx + b5x + 9y = -36Subtract 5x from each side:9y = -5x - 36Divide everything by 9:y = -5/9x - 4
What is 2x plus 3y minus 2 plus3x plus 6y plus 7?
It is an algebraic expression that can be simplified to: 5x+9y+5
5x - 9y -3?
(x+5)(x+5)
What is 5x-9y equals 7 7y-3x equals -5?
If: 5x-9y = 7 and 7y-3x = -5 Then: x = 1/2 or 0.5 and y = -1/2 or -0.5
What is the value of 5x-3x plus 5?
2x + 5
5x plus 9y equals 0 6x plus 6y equals 2?
5x + 9y = 06x + 6y = 2 use substitution method5x + 9y = 0y = -5x/96x + 6y = 2 substitute y with -5x/96x + 6(-5x/9) = 26x - 30x/9 = 2 multiply by 9 to both sides54x - 30x = 1824x = 18x = 24/18 = 4/3y = -5x/9 = (-5/9)x substitute x with 4/3y = (-5/9)(4/3) = -20/27Thus the solution is x = 4/3 and y = -20/27.
If x equals 5 and y equals 2 then 5x plus 9y equals?
I x=5 and y=2, then (5x5)=25 plus (9x2)=18. 25+18=43
What is the slope of any line parallel to the line formed by the equation 45x plus 9y equals 36?
The slope of any line parallel to the line described is -5. Solution: 45x+9y=36. Solve for y. 9y=36-45x. y= -5x+4 m=-5
What is the sum of this equation -5x plus y equals -12 -3x plus 6y equals -12?
-5x + y = -12- 3x + 6y = -12Since both of expressions have a value of -12, their sum is - 24. This is true only whenx = 20/9 and y = -8/9.-5x + y = -12y = 5x - 12- 3x + 6y = -12-3x + 6(5x - 12) = -12-3x + 30x - 72 = -1227x = 60x = 60/27x = 20/9y = 5x - 12y = 5(20/9) - 12y = 100/9 - 12y = (100 - 108)/9y = -8/9
How do you solve 6x-5y equals 22 and 9y plus 7 equals 5x plus 8?
1. 6x - 5y = 22 2. 5x - 9y = -1 1 times 5: 30x - 25y = 110 2 times 6: 30x - 54y = -6 Subtract : 29y = 116, so y = 4 and x therefore = 7
What is the value of x for 3x plus 5x equals 40?
5
9y plus 5 equals 0 what is y?
9y + 5 = 0 (-5 on both sides)9y = -5 (/9 on both sides)y = -5/9
