WebGaussian elimination is a method of solving a system of linear equations. First, the system is written in "augmented" matrix form. Then, legal row operations are used to transform the matrix into a specific form that leads the student to … WebAnswer: Given, x – 3y – 7 = 0 and 3x – 3y – 15 = 0 (a 1 /a 2) = 1/3 (b 1 /b 2) = -3/-3 = 1 (c 1 /c 2) = -7/-15 a 1 /a 2 ≠ b 1 /b 2 Since this pair of lines are intersecting each other at a unique point, there will be a unique solution. By cross multiplication, x/ (45-21) = y/ (-21+15) = 1/ (-3+9) x/24 = y/ -6 = 1/6 x/24 = 1/6 and y/-6 = 1/6

WebThe equation of a line is 3x + 4y - 7 = 0. Find: (i) the slope of the line (ii) the equation of a line perpendicular to the given line and passing through the intersection of the lines x – y + 2 = 0 and 3x + y – 10 = 0 Advertisement Remove all ads Solution 3x + 4y − 7 = 0 ... (1) 4y = −3x + 7 y = - 3 4 x + 7 4 (i) Slope of the line = m = - 3 4 Web14 nov. 2024 · Reduce to first order and solve y y ″ = 3 y ′ 2 Dividing both sides by y and re-arranging y ″ − 3 y ′ = 0. This is clearly an homogenous equation, a solution might be e 3 x to test this: y ′ = 3 e 3 x, y ″ = 9 e 3 x 9 e x − 9 e x = 0 Substituting y = u e 3 x, y ′ = u ′ e 3 x + 3 u e 3 x, y ″ = u ″ e 3 x + 3 u ′ e 3 x + 3 u ′ e 3 x + 9 u e 3 x lightyear 2022 full movie free
If we reduce 3x+3y+7=0 to form - Math Strategies
WebWithout graphing them, we can see that both have the same slope -3 which means lines are parallel. Hence the system of equations has no solution. So option (B) is the answer. Example 2: Determine whether the following system of equations have no solution, infinitely many solution or unique solutions. x+2y = 3, 2x+4y = 15.

The fact that a function may send 0 to 0 is not enough to guarantee that it is lin ear. Defining S( x, y) = (xy, 0) we get that S(0) = 0, yet S is not linear.
