Find Point Math

To find the solution of the system of equations y 29x 1 000 and y 49x the simplest thing to do is to use substitution because they re both already solved for y setting the two y s equal to one another you get 29x 1 000 49x subtracting 29x from each side you then get 1 000 20x dividing each side by 20 you have that x 50. Find the slope or gradient from 2 points. Put the slope and one point into the point slope formula 3.

Because x is the number of pairs of jeans it.

Find point math. F x is concave downward up to x 2 15. Find the slope of the line. The second derivative is y 30x 4. The derivative is y 15x2 4x 3.

To find the required point we have to apply this ratio in the formula 0 y 2 5 5 2 5 2 3 5 2 5 2 0 y 10 10 7 15 2 7 0 y 0 17 7 hence the required point is 0 17 7. F x is concave upward from x 2 15 on. Point a is 6 4 at x is 6 y is 4. We know two points.

And the inflection point is at x 2 15. What is the slope or gradient of this line. There are 3 steps to find the equation of the straight line. And 30x 4 is negative up to x 4 30 2 15 positive from there onwards.
