What is the ordered pair of 5x equals 4y equals -20?
5x=4y=-20 x=-4 y=-5 (-4,-5) is the ordered pair
What is the x-intercept and y-intercept of 5x subtract 4y equals 1?
y-intercept: -1/4 x-intercept: 1/5 5x-4y=1 -4y=-5x+1 y=5/4x+1/-4 5x-4y=1 5x=4y+1 x=4/5y+1/5
What is the xintercept for 5x - 4y equals 18?
To find the x-intercept for 5x - 4y = 18, plug in a 0 for the y value and solve for x. 5x - 4(0) = 18 5x = 18 x = 18/5 or 3.6 The line will hit the x-axis at (3.6,0)
Which is the slope of a line parallel to the line 5X-4y equals 9?
To answer this question we need to first get the slope of the line 5x-4y=9 by rearranging it in the form of y=mx+b: 5x-4y=9 4y=5x-9 y=(5/4)x-9/4 Since the slope of parallel lines are negative reciprocals of each other, the negative reciprocal of 5/4 is -4/5, therefore the slope of a line parallel to the line 5x-4y=9 is -4/5
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)
Slope of 5x plus 4y equals 20?
5x + 4y = 204y = -5x + 20y = (-5/4)x + 5
What is the ordered pair of 5x equals 4y equals -20?
5x=4y=-20 x=-4 y=-5 (-4,-5) is the ordered pair
What is the x-intercept and y-intercept of 5x subtract 4y equals 1?
y-intercept: -1/4 x-intercept: 1/5 5x-4y=1 -4y=-5x+1 y=5/4x+1/-4 5x-4y=1 5x=4y+1 x=4/5y+1/5
Which line represents 5x plus 4y equals 20?
5x+4y=20 is technically the equation of a line. A more familiar representation of the line is in "y equals" notation. This simply means that the y variable has been isolated (this notation is usually required for graphing calculators). To get the equation in y equals notation, simply isolate the y variable: 5x+4y=20 4y=(-5)x+20 y=((-5)x+20)/4
What is the answer to 5x - 4y plus 9y plus x -9 plus 7?
5x-4y+9y+x-9+7 = 5x + x - 4y + 9y - 9 + 7 = 6x + 5y - 2 ■
Is 5x plus 4y equals 0 a function?
Yes it is a function. 5x + 4y = 0 the same as: 5x = -4y You can also solve for either variable. x = - ( 4 / 5 ) y y = - ( 5 / 4 ) x
What is the slope of the equation 5x plus 4y equals negative 3?
5x+4y = -3 4y = -5x-3 y = -5/4 x - 3 Slope is -5/4.
What is the xintercept for 5x - 4y equals 18?
To find the x-intercept for 5x - 4y = 18, plug in a 0 for the y value and solve for x. 5x - 4(0) = 18 5x = 18 x = 18/5 or 3.6 The line will hit the x-axis at (3.6,0)
X plus 2y equals -1 5x - 4y equals 16?
x+2y = -1 and 5x-4y = 16 Solving the simultaneous equations gives: x = 2 and y = -1.5
What is the point of intersection of the equation 4y equals 5x with the line joining the points 13 17 and 19 23 on the Cartesian plane showing work?
Points of line: (13, 17) and (19, 23) Its slope: 1 Its equation: y = x+4 => y-x = 4 Multiply all terms by 4: 4y-4x = 16 Equation of: 4y = 5x => 4y-5x = 0 Subtacting equations: x = 16 By substitution point of intersection is at: (16, 20)
What is the slope given 5x plus 4y equals -2?
5x + 4y = -2Subtract 5x from each side:4y = -5x - 2Divide each side by 4:y = -1.25 x - 0.5In this form, we can look at it and see that the slope of the graph is -1.25and the y-intercept is -0.5 .
5x-4y equals -41 4x plus 35 equals?
5x - 4y = -41 => 5x = 4y - 41 => x = (4y - 41)/5 Then 4x + 35 = 4*[(4y - 41)/5] + 35 = 16y/5 - 164/5 + 35 = 16y/5 -11/5 or (16y - 11)/5
