5x plus 2y equals 19 x - 2y equals -1?
(3, 2)
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 the x intercept of 5x - 2y 20?
Assuming you meant 5x-2y=20... 5x - 2(0) = 20 5x = 20 x = 4 X-intercept is 4
What is the ordered pair for 2x plus 5y equals 16 plus -5x minus 2y equals 2?
2x + 5y = 16 + (-5x) - 2y = 2 That gives 2x + 5y = 2 . . . . . . . . . . (I) and -5x - 2y = - 14 or 5x + 2y = 14 . . . . (II) (I)*5: 10x + 25y = 10 (II)*2: 10x + 4y = 28 Subtracting the second from the first, 21y = -18 so y = -18/21 = -6/7 and then by (I) x = 1 - 5y/2 = 1 - 5/2*(-6/7) = 1 + 15/7 = 22/7 So the ordered pair is (22/7, -6/7)
Simplify 3x plus 2y plus 2 equals 4y plus 4?
The equation can be simplified to show a value of Y in terms of X. 3X + 2Y +2 = 4Y + 4 3X + 2 = 2Y + 4 3X -2 = 2Y and 2Y = 3X - 2 means that Y = (3/2 X) -1
10x plus 2y plus 8z-5x plus 4z-4y equals?
10x + 2y + 8z - 5x + 4z - 4y = 10x - 5x + 2y - 4y + 8z + 4z = (10 - 5)x + (2 - 4)y + (8 + 4)z = 5x - 2y + 12z
What is the slope and y-intercept of 5x plus 2y plus 3 equals 0?
Put in point slope/function form. 5X + 2Y + 3 = 0 5X + 2Y = - 3 2Y = - 5X - 3 Y = - 5/2X - 3/2 slope = - 5/2 ---------------- Y intercept = - 3/2 -------------------------
5x plus 2y equals 19 x - 2y equals -1?
(3, 2)
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.
What is 5x - 3y -7x plus 2y plus 3x?
5x - 3y -7x + 2y +3x = (5-7+3)x + (-3+2)y = x - y
How do you solve for 5x plus y equals 1 and 3x plus 2y equals 2?
For 5x+y=1, you would subtract 5x from each side, so you would get y=1-5x For 3x+2y=2, you would subtract 3x from each side, and then divide by 2. 2y=2-3x y=1-(3/2)x
What is the slope-intercept form of 5x plus 2y equals negative 4?
5x+2y=-4 Subtract 5x from both sides 2y=-5x-4 divide by two on both sides y=-5/2x-2 y = -2.5x -2 in slope-intercept form
What is a slope of a line whose equation is 2y plus 5x equals 4?
If: 2y+5x = 4 Then: y = -2.5x+2 whereas the slope is -2.5 and the y intercept is 2
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
How do you solve the system of equations 5x-2y equals 4 and 3x plus y equals 9 using multplication with the addition method?
5x-2y = 4 2(3x+y = 9) Multiply all terms in the second equation by 2: 5x-2y = 4 6x+2y = 18 Add the equations together: 11x = 22 Divide both sides by 11 to find the value of x: x = 2 Substitute the value of x into the original equations to find the value of y: Therefore: x = 2 and y = 3
What is the answer to this problem 5x plus 2y equals 19 and x-2y equals -1?
x = 3 and y = 2
What is the slope of 5x-2y equals 11?
5x-2y=11 -2y=-5x+11 y=(5/2)x - 11/2 Slope is 5/2
