I think this is false. p +/- z*sqrt (pq/n) . Notice that the formula has sqrt of n.

So first divide the equation on both sides by 3. We get $x - 2y = 4
$ . Slope-y-intercept form is of the form $y = mx + b$ . Rearranging $x - 2y = 4
$ , we get $2y = x - 4$ . Divide by two, we get $y = \frac{x}{2} - 2$ , which is of that form.

Graphing: The y intercept is at -2, and the slope is 1/2.

Solve the exponential equation by the method of relating the bases, first rewriting the equation in the form

Nookie1986 [14]

Answer:

x = 1/3

Step-by-step explanation:

Both bases can be written as powers of 6.

36^x = (1/6)^(x-1) . . . . . . given

(6^2)^x = (6^-1)^(x -1) . . . . . bases as powers of 6

6^(2x) = 6^(-x+1) . . . . . . . . . simplify exponents

2x = -x +1 . . . . . . . . . . . . . . . .equate exponents of the same base

3x = 1 . . . . . . . add x

x = 1/3 . . . . . divide by 3
