I have not learned this stuff yet, but by using online calculators, I can determine that the vertex form of your equation is:

n/a. It cannot be written in vertex form because it is not a conic section.

But if you are referring to x^2 - 12x + 8, the answer is: Y = (x - 6)² - 28 (i think)

(x-4)^2-19=y
you first add the three to the other side, then add 16 on both sides, make the left side x-4 squared, and lastly you subtract 19 from both sides.

The ratio of two complementary angles is 17:13. What is the measure of the smaller angle?

Mariana [72]

We know by definition that complementary angles add up to 90 degrees. We can set up an equation using the ration given:

17x+13x=90, with x representing the amount you need to multiply the ratio by to get 90.

17x+13x=90
30x=90
x=3

We now know that the number we multiply the ratio by is 3. The smaller number in the ratio is 13, and so therefore we multiply it by 3.

3*13=39

The answer is 39 degrees.
