What is the solution of this linear system 3x plus 5y equals -1 2x-5y equals 16?
3x + 5y = -1 2x - 5y = 16 Add the two equations: 5x = 15 or x = 3 Substitute for x in the first equation: 3*3 + 5y = -1 15 + 5y = -1 5y = -10 so y = -10/5 = -2 The solution is (x, y) = (3, -2)
How do you rewrite this equation so that y is a function of x -- 3x plus 5y equals 7?
Because of the limitations of the question software, it was not possible to determine what the original equation was supposed to be, so we assumed it is 3x + 5y = 7. It could have just as easily been 3x - 5y = 7, or even 3x/5y = 7.So, let's solve them all for x.3x + 5y = 73x = 7 - 5yx = (7 - 5y)/3How about 3x - 5y = 7?3x - 5y = 73x = 7 + 5yx = (7 + 5y)/3And 3x/5y = 7?3x/5y = 73x = 35yx = 35y/3 Solving for y The above equations wrote the equation so that x is a function of y, not the other way around. Here's how to rewrite the equation so that y is a function of x: 3x + 5y = 7 5y = -3x + 7 y = (-3x + 7)/5
How can you get coefficients that are equal for y. 3x plus 5y equals 7 2x plus 15y equals 11?
Multiply the first equation by 3 to give 9x + 15y = 21
What is the slope of 2x plus 5y equals 10?
To solve this, present the equation in the standard slope/intercept form of y = mx + c. 'm' is the slope. 2x + 5y = 10 5y = -2x + 10 y = -2/5x + 2 Therefore, -2/5 is the slope.
What is 5y equals 9 plus 2y equals?
Solving for y: 5y = 9 + 2y 5y - 2y = 9 3y = 9 y = 9/3 = 3
-20x 5y equals 40 changed to slope-intercept form?
If the equation is -20x-5y=40 then the answer is -5y=20x+40 which equals y=-4x-8 If the equation is -20x+5y=40 then the answer is 5y=20x+40 which equals y=4x+8
40 plus 9 equals 5y plus 9?
40 + 9 = 5y + 9 Since 9 is present on both sides of the equation,therefore we can strike it off on both sides,the remaining equation being 40 = 5y or 5y = 40 5y = 40 or y = 40/5 Therefore,y = 9 .
Is 3x equals 5y a linear equation?
3X = 5Y solve for Y Y = 3/5X this is by definition a linear equation solved. You can plat this straight line on a graph.
What is the equation of 5y equals 35?
The equation is [ 5y = 35 ].The solution to the equation is [ y = 7 ].
How do you graph -5y equals -300?
First, you must simplify the equation.(-5y)=(-300)[Divide by -5]y=60Now, the equation is as simple as it can be. Draw a horizontal line across y's 60. You are now finished!
What is 5y-90x equals 80?
It's a non-standard form of the equation for a straight-line graph with a slope of 18 and a y-intercept of 16.
How do you graph 3x plus 5y equals -2?
In order to graph this equation, you have to isolate y. 3x + 5y = -2 3x + 5y + 2 = 0 3x + 2 = -5y (3x+2)/-5 = y Now you can plug it into a graphing calculator. If you're graphing by hand, the equation you'll want to use is: (-3/5)x - (2/5) = y So the slope will be negative 3/5 and the y-intercept is -2/5.
What are the x- and y-intercepts of the line with equation 4x plus 5y equals 40?
First, put the equation in slope-intervcept form y=mx + b 5y=4x + 40 The y intercept is where x=0 so- 5y= 4(0) +40 solve for y y intercept = (0,8) For the x intercept, y=0 0=4x+40 -4x=40 x= -10 xintercept =( -10.0)
What is the slope of every line perpendicular to the graph of this equation 4x plus 5y equals 7?
4x+5y = 7 5y = -4x+7 y = -4/5x+7/5 in slope intercept form So the slope of the perpendicular line is plus 5/4
How would you turn 8x-5y equals -40 into slop intercept?
8x-5y = -40 -5y = -8x-40 y = 1.6x+8 which is now in slope intercept form
How would you graph the equation x plus y equals 5?
x + y = 5y = -x + 5The graph is a straight line, with [ slope = -1 ], passing through the point [ y = 5 ] on the y-axis.
Determine the X - intercept of the graph of the equation 6 x - 5 y equals 36?
6x - 5y = 36At the x-intercept, y=0.6x = 36x = 6
