1. 143+9 = 152
2. 2x=4, solve for x = 2
3. 945-100 = 845
4. 1/8=1/x, solve for x = 8
but how in the world did you get into 11th grade?

finished the sq. to locate the answer: y = -2x^2 + 10x y = -2(x^2 - 5x) to finish the sq., take 1/2 of the x time period's coefficient and sq. it. upload that contained in the parentheses. The sq. of five/2 is 25/4, so interior the parentheses upload 25/4. This gives you -2(25/4) it extremely is -25/2 to the equation, as a thanks to keep it balanced you may want to characteristic 25/2 exterior the parentheses. y = -2(x^2 - 5x + 25/4) + 25/2 y = -2(x - 5/2)^2 + 25/2 The time period -2(x-5/2)^2 can pass from adverse infinity to 0. So there is not any decrease certain to the graph, yet there is an higher certain: it may't pass any larger than 25/2. 25/2 is the optimum fee. yet otherwise to attempt that's to take a shortcut to locate the middle of the parabola. that's x = -b/(2a), the position a is the coefficient of x^2 and b is the coefficient of x. So x = -10/(2(-2)) = 5/2 is the middle. The y fee that is going with which may be discovered only by plugging it into the equation, and that would want to provide the minimum or optimum of the parabola.

Looks as though you are about to get grade 11 in your test.

Fail....and get kicked off the team. Your attempt to be funny is idiotic. Not to mention my 5th graders do your "11th grade" math the second month of school.

You know, this is silly. The phrasing and spelling of your question is too outrageous to be real. So, "No soup for you! Go to the end of the line!"
