Do you know how to use parentheses? I don't know if I should read your problem as written or how I think you intended it to be written. Ex: 5x divided by (x-2) would be written as: 5x/(x-2), not 5x/x-2.
It's not clear what you are asking. If you are dividing 2 by quantity [(1-x)*(1+x)], then your answer is sqrt3/3; where x does not equal 1 or -1 (that would induce division by 0).
cancel the y's, so answer is 7/(4y-1)
Let x = days worked Let 30 - x = days not worked, so $5.5 * x - $6.6 * (30 - x) = 0 days worked = 16 and 4/11 days days not worked = 13 and 7/11 days. Goofy answers, as far as I'm concerned!
two solutions is correct, but the equation for a circle is: (x-a)^2 + (y-b)^2 = r^2; where (a, b) is the center of the circle, so (x-0)^2 + (y-1)^2 = 9 The points of intersection are: (1.836377228, 3.372281323) and (-1.836377228, -1.372281323)
18; for the six faces, the sums of opposing sides are 18 and 10, 14 and 14, and 18 and 10. I numbered the vertices as such: plane 7, 6, 1, 4; corresponding plane 0, 5, 2, 3
one pound; Each bag weighs 2 pounds. If the bag is 2/3's full, one additional pound will fill it.
d) 20; transitive property, so 2v + 10 = 1.6v + 18
a) (-4, 0); Find the slope of each set of points. Set up both equations, using the slope for each, in the form y = mx + b. Insert each slope. Use a point from each equation to determine the y-int for each (-4 and 8, respectively). Solve using systems of equations.
You have the correct answer. Use your calculator for your choices and see which one gives you the same answer: both 1st and last answers give the same answer, but the last one is the correct answer. By the way, you are correct in using the Pythagorean Theorem, which gives hyp ...
