Equations: 7x+4y = 9 and 2x+3y = 1
Multiply all terms in the 1st equation by 2 and all terms in the 2nd equation by 7
So: 14x+8y = 18 and 14x+21y = 7
Subtract the 1st equation from the 2nd equation: 13y = -11 => y = -11/13
By substituting y = -11/13 into any of the equations x = 23/13
Therefore the solutions are: x = 23/13 and y = -11/13
Eqn (A): => 2x + 5y = 16 Eqn (B): => 5x + 2y = -2 5*Eqn (A) - 2*Eqn (B): 21y = 84 => y = 4 Substituting for y in Eqn (a): x = -2
If: y = 3x+4 and y = 2-7x Then: 3x+4 = 2-7x So: 3x+7x = 2-4 => 10x = -2 => x = -1/5 By substitution: y = 17/5 Solution: x = -1/5 and y = 17/5
he Stages for acute injury is the RICE treatment or in more recent times the POLICE treatment
5 stages of grief
If: x+y = 7 and x2+y2 = 25 Then: x = 7-y and so (7-y)2+y2 = 25 => 2y2-14y+24 = 0 Solving the quadratic equation: y = 4 and y = 3 By substitution points of intersection: (3, 4) and (4, 3)
1 If: 2x+5y = 16 and -5x-2y = 2 2 Then: 2*(2x+5y =16) and 5*(-5x-2y = 2) is equvalent to the above equations 3 Thus: 4x+10y = 32 and -25x-10y = 10 4 Adding both equations: -21x = 42 or x = -2 5 Solutions by substitution: x = -2 and y = 4
Eqn (A): => 2x + 5y = 16 Eqn (B): => 5x + 2y = -2 5*Eqn (A) - 2*Eqn (B): 21y = 84 => y = 4 Substituting for y in Eqn (a): x = -2
Waterfall is one of the software development life cycle model. Waterfall model has five stages.
identify the problem, determine options, implement solutions
If: y = 3x+4 and y = 2-7x Then: 3x+4 = 2-7x So: 3x+7x = 2-4 => 10x = -2 => x = -1/5 By substitution: y = 17/5 Solution: x = -1/5 and y = 17/5
identifying a problem thinking of possible solutions deciding on the best solution communicating implement evaluate (:
Points: (7, 5) Equation: 3x+4y-16 = 0 Perpendicular equation: 4x-3y-13 = 0 Equations intersect at: (4, 1) Length of perpendicular line: 5
The stages in the route to enquiry typically include awareness (identifying a problem or need), consideration (researching potential solutions), evaluation (comparing options), decision (making a choice), and post-purchase evaluation (reflecting on the experience).
Equation: 3x+4y-16 = 0 Perpendicular equation: 4x-3y-13 = 0 Both equations intersect at: (4, 1) Perpendicular distance: square root of (7-4)2+(5-1)2 = 5
Points: (4, -2) Equation: 2x-y-5 = 0 Perpendicular equation: x+2y = 0 Equations intersect at: (2, -1) Perpendicular distance is the square root of: (2-4)2+(-1--2)2 = 5 Distance = square root of 5
It has 3 stages. The stages are : Egg, Nymph and the Adult.
The three stages that are needed for development of fruit fly larvae are molting stages, pupil stages, and metamorphosis stages.
