Finding the coordinates of the point of intersection of these lines? Please help!?
The point of intersection is the x & y values that you get when you solve both equations simultaneously. 3x + 4y = 10 5x - 6y = 23 Multiply every term of the first equation by 1.5 so that we can eliminate the y term: 4.5x + 6y = 15 5x - 6y = 23 9.5x = 38 x = 4 Now plug in the x value into one of the original equations & solve for y: 3x + 4y = 10 3(4) + 4y = 10 12 + 4y = 10 4y = -2 y = -1/2 So, the point of intersection is (4, -1/2)
Find the coordinates of the points of intersection of the line y+2x=11 and the curve xy=12 ??
Find the coordinates of the points of intersection of the line y+2x=11 and the curve xy=12 i find an answer for this question but i am not sure and i dont have the answer key. Thanks for answering
Plx help!! find the corrdinates of the point of intersection of the lines y = 3x + 1 and x + 3y = 6?
1) The coordinates of the point of intersection are found where the values of both lines are equal. So y = 3x + 1 and x + 3y = 6 Choosing one of the two equations, solve for one variable, then the other: x + 3y = 6 Since, from the first equation y = 3x + 1, substitute that into the second equation x + 3y = 6 == > x + 3(3x + 1) = 6 x + 9x + 3 = 6 10x = 6 - 3 x = 3/10 Then substituting this in for x in the first equation y = 3x + 1 y = 3(3/10) + 1 y = 9/10 + 1 = 19/10 So x = 3/10, y = 19/10 2) The line L is parallel to Y = -2x+ 1 and passes through the point 5,2. Two or more parallel lines have equal slopes. Since line Y has a slope of -2, so does the new line. Since you have both a coordinate pair and a slope, we may proceed to checkout.... Use the point-slope form of the equation: y - y1 = m(x - x1) y - 2 = -2(x - 5) [Where m = -2, (x1,y1) = (5,2)] y - 2 = -2x + 10 y = -2x + 12 Which is the equation for the new line. All that remains is to find the x- and y-intercepts. To find the y-intercept, set x = 0 y-int = -2(0) + 12 Similarly, to find the x-intercept set y = 0 0 = -2x + 12 2x = 12 x-int = 6 So the x- and y-intercepts are (6,0) and 0,12) respectively.
How to find the x-coordinates of the points of intersection? PLEASE HELP, 10 POINTS?
The equation of a curve C is y=2x^2-8x+9 and the equation of a line L is x+y=3. Find the x-coordinates of the points of intersection of L and C, and show that one of these points is also the stationary point of C. How can I solve this problem? Please help, 10 points??
How do u find the coordinates of the points of intersection of the parabola y= -x2+9x-3 and the line y=3x?
Substituting Y = 3x in the parabola Y = -x^2 + 9x - 3 gives 3x = -x^2 + 9x - 3 and x^2 - 6x + 3 =0. Therefore, x = [-(-6) + or - sqrt of {(-6)^2 - 4*3}]/2. In this x will have two answers. x = [6 + sqrt of (36 - 12)]/2 or [6 - sqrt of (36 - 12)]/2 x = [6 + sqrt of (24)]/2 or [6 - sqrt of (24)]/2 x = [3 + sqrt of (6)] or [3 - sqrt of (6)] Substituting the above two x values in y = 3x, you will get the corresponding values for y.
Find the coordinates of the points of intersection of the parabola y=x^2-ax and line y=bx-ab plz show steps?
You need to know where one equation equals the other, so: x²-ax = bx -ab x² - (a+b)x +ab = 0 (x-a)(x-b) = 0, x= a or b, so plug those in to the other equation: y = ab-ab =0 when x = a, and y = b²-ab when x = b, so: (a, 0) and (b, b²-ab)
What is the point of intersections of the line 3x+7y=14 and the y-axis?
The point of intersection asked in on the y axis, it means that the point intersects at y where x is 0.Therefore, x is 0.Putting the value of x in the equation, we can easily find the value of y. The value of y indicates that at what point it will intersection.So, 3x+7y=143(0)+7y=140 +7y =147y=14y=14/7 = 2Therefore, y = 2.
