1. ### math help pls!?

The curly delta means the same thing as the "d". I agree that the whole expression APPEARS to mean the same thing as the integral from x = 1 to 2 of  (x^3 - 16 + 64/x^3) dx which would be (1/4)x^4 - 16x - 32/x^2, to be evaluated at x = 2 and 1, which comes out to (1/4)16 - 32 - 8 - (1/4...

66% off ==> 244.80 = (1- 66/100)* x where x is the original (before the 66% reduction) price so x = 24480/34  (NOT x = 24480/66) ==> x = \$720

3. ### Can I use the quadratic formula if the exponents are in the same ratio as a normal quadratic funtion?

Yes, the quadratic formula can be used to solve ax²ⁿ + bxⁿ + c = 0. Note, however, that it cannot be used in the example that you gave, because 0.954/0.478 ≅ 1.996, not 2.

4. ### How do I find the values of z and a?

Assuming that the figure is a rhombus; then z + 6 = 3z + 2 so 2z = 4 and z = 2 and 7a + 5 = 5a + 9 so 2a = 4 and a = 2 Update if you need more, and please choose  a best answer from among those you get.

5. ### (math help) Scatter Plot equation?

y = mx + c... m = rise/run = change in y / change in x = (80-62)/(6-0) = 18/6 = 3 so we have y = 3x + c when x = 0, y = 62 ==> c = 62 so, yes you are right --- y = 3x + 62

6. ### Better ways to solve the following equation with only integer answers 6 = (J + I + K)/ IK given that J is a parameter?

One can know a lot by inspecting the magnitude of A and B | B | = | I K | usually >> | A | = | I + K | So as | B | is big, | 6 B | is even bigger As 6 B = J+A...
