How to do 40
In Problems 39-42, multiply both sides of the equation by the LCD and solve the resulting quadratic equation. 39. x 15 w xwgisla 3d x - 2 x + 1 129
16. Derive the basic Euler's formula by integrating both sides of the equa tion y' = f(x,y) on the interval x's x x" +1. Approximate the inte- gral of the right side by replacing the function f(x, y) by its value at the left endpoint of the interval of integration.

) Solve the inequality. Write the answer using both set-builder notation and interval notation. Graph the solution set on a number line. Multiply both sides of the inequality by the LCD first to clear fractions. 3/4 x+1/2<1/3 x+2
HOW DO I SOLVE A QUADRATIC EQUATION BY FACTORING?Do you have a specific one? You factor it in this form: (x-a)(x-b)=0 then both factors , x-a, and x-b can be set equal to zero, and then x=a, and x=b.

43. Use the regression equation below to predict the profits for the restaurant when the population size is 14.8 thousand people. (Plug in 14.8 for X in the equation and calculate Y) Regression Line: Y--30.3091+6.0211 X 44. (True or False?) This correlation study proves that more people in a city will cause the restaurant profits to increase (True or False?) It will be fine to use the regression equation to predict the profits for the...
