point for 2x-3y=7

The points of intersection with x-axis is determined by letting y = 0. Putting y = 0, - sin 2x = 0 This implies the curve intersects the x-axis at the points where The points at which the tangent is p..

Question: Find the ratio in which the straight line 2x + 3y - 5 = 0 divides the line joining two points (-4,1) and (2,7). Answer: Let m:n be the ratio in which the line divides the line joining the points (-4,1) and (..

Put x = 0, y = -sin2x = 0. This implies (0, 0) is a point on the curve or the curve passes through the origi..

2x+3=4 Coordinates The co-ordinate of the foot of the perpendicular draw on the x-axis from the given point P is x-coordinate of the point P ('a'). Similarly 'b' is the y-coordinate of the point P. ..

Maximum number of electrons that can be accommodated in a shell is given by 2n 2 where n=shell number For 1 s t energy level, n = 1 Maximum number of electrons in 1 s t energy level = 2n 2 2 x (1) 2 = 2 Fo..

The figure shows a long straight wire carrying current and point P where the field is to be obtained. OP = a = 0.1m. The magnetic field B is B = m o I/2 a = (4 x 10 - 7 x 4) 2 x 10 - 1 = 8 x 10 - 6 T Accordi..

Question: Exhibit graphically the solution sets of the following linear inequations. Answer: We draw the graph of 2x + 3y = 6 by taking the points A(0, 2) and B(3, 0). The line divides the region into two, parts..

Question: Find the equation of two lines passing through the point (4,5) Answer: The equation of the line through (4,5) with slope m is y - 5 = m(x - 4) The slope of line 2x - y + 7 = 0 is 2. ..

Question: In the figure, ABCD is a parallelogram. P is a point on BC such that BP:PC = 1:2. DP produced meets AB produced at Q. If area of D CPQ = 20 cm 2 , find [3 Mark] i. Area of D BPQ ii. Area of D CDP iii. Area of parallelogram ABCD. ..
