What is the system of equations and enter the solution as an ordered pair 9x - 2y equals 73 5x - 9y equals 9?
(1) 9x-2y=73 (2) 5x-9y=9 from (1) 9x-2y+2y=73+2y => 9x= 73+2y => x = (73+2y)/9 put into (2) 5x-9y = 9 => 5(73+2y)/9 - 9y=9 => 10y/9 + 365/9 -9y = 9 => 10y/9 - 9y = 9 -365/9 = -284/9 => -71y/9 = -284/9 => 71y= 284 => y = 284/71 = 4 and x = (73+2*4) / 9 = 9
What is 5x-2y-5x plus 7y simplified?
5y explanaition 5x-5x=0, 0-2y=-2y, -2y+7y=5y
How do you get y by itself in this equation 5x-2y4?
To do this equation, there would have to be an = in it. If you mean 5x-2y=4, then: 5x-2y=4 -5x -5x = -2y=4-5x Hope this helped!
What is a solution to the equation 5x 2y-1?
Without an equality sign it cannot be classed as an equation therefore it follows that there is no solution.
What is the ordered pair for 9x-2y equals 73 5x-9y equals 9?
9x - 2y = 73 . . . . . (a) 5x - 9y = 9 . . . . . (b) (a)*9: 81x - 18y = 657 (b)*2: 10x - 18y = 18 Subtract: 71x = 639 so x = 9 Substitute in (a): 81 - 2y = 73 2y = 8 so y = 4 The ordered pair is (9, 4)
Which is a solution to the equation 5x plus 2y equals 9?
If: 5x+2y = 9 Then: y = -2.5x+4.5 in slope intercept form
What is the system of equations and enter the solution as an ordered pair 9x - 2y equals 73 5x - 9y equals 9?
(1) 9x-2y=73 (2) 5x-9y=9 from (1) 9x-2y+2y=73+2y => 9x= 73+2y => x = (73+2y)/9 put into (2) 5x-9y = 9 => 5(73+2y)/9 - 9y=9 => 10y/9 + 365/9 -9y = 9 => 10y/9 - 9y = 9 -365/9 = -284/9 => -71y/9 = -284/9 => 71y= 284 => y = 284/71 = 4 and x = (73+2*4) / 9 = 9
Graph the solution set of the linear inequality 5x-2y4?
graph the inequality 5x+2y<4
What is 5x-2y-5x plus 7y simplified?
5y explanaition 5x-5x=0, 0-2y=-2y, -2y+7y=5y
Rewrite the equation 5x-2y0 in slope-intercept form?
5x - 2y = 05x - 5x - 2y = 0 - 5x-2y = - 5x(-2y)/-2 = (-5x)/-2y = (5/2)x where the slope is 5/2 and the y-intercept is 0.
How do you get y by itself in this equation 5x-2y4?
To do this equation, there would have to be an = in it. If you mean 5x-2y=4, then: 5x-2y=4 -5x -5x = -2y=4-5x Hope this helped!
What is the value of the expression 5X-2y when x equals 9 and y equals 4?
5X - 2Y X = 9 Y = 4 5(9) - 2(4) 45 - 8 37 is the value
What is the value of the expression 5x-2y when x equal 9 and y equal 4?
5x = 5 times 9, 2y = 2 times 4 so 45 - 8 ie 37
What is a solution to the equation 5x 2y-1?
Without an equality sign it cannot be classed as an equation therefore it follows that there is no solution.
5x plus 3y-x plus 10-2y?
5x + (3y-x) + (10-2y) = 5x + 3y - x + 10 -2y = 5x - x + 3y - 2y + 10 = 4x + y +10
What is the ordered pair for 9x-2y equals 73 5x-9y equals 9?
9x - 2y = 73 . . . . . (a) 5x - 9y = 9 . . . . . (b) (a)*9: 81x - 18y = 657 (b)*2: 10x - 18y = 18 Subtract: 71x = 639 so x = 9 Substitute in (a): 81 - 2y = 73 2y = 8 so y = 4 The ordered pair is (9, 4)
