How many solutions does this equation have 2x y-6 5x-3y7?
If you mean: 2x+y = -6 and 5x-3 = 7 then the solutions are x = -1 and y = -4
What is the answer to this equation y equals -2x plus 3?
y=-2x+3 is an equation. It does not have an answer. If the question is "what if y=0?" then the answer is x=3/2.
What equation has a slope of -2?
Technically, since there are an infinite amount of numbers, there are an infinite amount of answers to this question. But if you want a "Y-intercept" form equation, then there are: y = -2x y = -2x + 1 y = -2x + 2 y = -2x + 3 and so forth. y = -2x + 983475686348684322643843268342648
How do you solve y equals x plus 3 and -2x plus y equals -4?
(1) y = x + 3 (2)-2x + y = -4 It is usual to present the equations showing one unknown expressed in terms of the other unknown. This is already the case in Equation (1). Restructuring Equation (2) gives y = 2x -4 (1) y = x + 3 (3) y = 2x - 4 Now subtract Equation (1) from Equation (3) to eliminate y. y - y = 2x - x -4 -3 : 0 = x - 7 : x = 7 Substitute for x in Equation (1) y = 7 + 3 : y = 10
What is 3y-9 equals 2x in y intercept?
To put the equation 3y - 9 = 2x in y-intercept form (y = mx + b): 3y - 9 = 2x 3y = 2x + 9 (add 9 to both sides of the equation) y = 2/3 x + 3 (divide all terms by 3) The y-intercept is the b term in the equation, which in this example is 3.
How many solutions does this equation have 2x y-6 5x-3y7?
If you mean: 2x+y = -6 and 5x-3 = 7 then the solutions are x = -1 and y = -4
What is the answer to 2 -1 y equals 2x-1?
There are infinitely many solutions. These are coordinates of all points on the line given by the equation 2 - y = 2x - 1 or 2x + y = 3.
Use the T table to determine 3 solutions to this equation 4x - 2y equals 8?
using the t-table determine 3 solutions to this equation: y equals 2x
What is the answer to this equation y equals -2x plus 3?
y=-2x+3 is an equation. It does not have an answer. If the question is "what if y=0?" then the answer is x=3/2.
Which equation represents a line that is parallel to the line y equals 3-2x?
5
What is the vertex of the equation y equals 2x-1?
3
Find three different ordered pairs that are solutions of the equation y equals 2x-1?
3
What is the slope of the line y 2x - 3?
-1
Find the slope and the y-intercept what linear equation. Then graph 2x plus y equals -3?
2x plus y = -3 (subtract 2x from both sides) y = -2x - 3 slope = -2 y-intercept = -3
What are the solutions to the simultaneous equation of 2x plus y equals 5 and x squared -y squared equals 3 showing work?
2x + y = 5 . . . thus y = 5 - 2x x2 - y2= 3 . . . . now substitute for y in this equation. x2 - (5 - 2x)2 = 3 . . . and after expansion this becomes, x2 - 25 + 20x - 4x2 = 3 -3x2 + 20x - 28 = 0 . . . and this factors as, (-3x + 14)(x - 2) = 0 Then, x = 2 , x = 14/3 When x = 2, then 2x + y = 5 gives the result y = 1. When x = 14/3 then 2x + y = 5 gives the result y = -13/3.
