The answer would be 210 because when you are trying to find the bigger number of the 2 you divide the smaller by the percentage in decimal form.

63/.30=210

Therefore the answer is 210

Answer:

210

Step-by-step explanation:

You first have 30% * x = 63

Then, you multiply both sides by 100 and divide both sides by 30:

x = 63 * $\frac{100}{30}$

Then, you have your answer:

x = 210

Factor 9y2 - 12y + 4. (3 y - 2)(3 y + 2) (3 y - 4)( y + 1) (3 y - 2) 2

lozanna [386]

Answer:

(y - 2)²

Step-by-step explanation:

9y² - 12y + 4 ← is a perfect square of the form

(ax - b)² = a²x² - 2abx + b²

Compare like terms with 9y² - 12y + 4, thus

a² = 9 ⇒ a = 3

b² = 4 ⇒ b = 2 and

- 2ab = - 2 × 3 × 2 = - 12

Thus

9y² - 12y + 4 = (3y - 2)²

Determine the vertical asymptote for the rational function f(x) = x - 4 over 2x + 3.

mr_godi [17]

Vertical asymptotes happen at x=a if the function is undefined at x=a.

This is a rational functions, and rational functions are not defined when the denominator is zero, since you can't divide by zero.

In this case, the denominator is zero if

$2x+3=0 \iff 2x=-3 \iff x=-\drac{3}{2}$

And thus the function has a vertical asymptote at x= -3/2
