F(x)=-2^2+16x-13
In vertex form
2 answers:
Answer:
Step-by-step explanation:
<u>Assumed it is:</u>
<u>Converting into vertex form:</u>
f(x) = - x² + 16x - 13 = - (x² - 16x + 64 - 64) - 13 = - (x - 8)² + 64 - 13 = - (x - 8)² + 51
<u>Given </u> <u>:</u> <u>-</u>
<u>To </u> <u>Find</u> <u> </u> <u>:</u> <u>-</u>
To convert it in vertex form .
<u>Answer </u> <u>:</u> <u>-</u>
We have ,
x² + 16x -13 x² + 2*8*x -13
Add and subtract 8² .
x² + 2*8*x + 8² - 8² -13 ( x² + 2*8*x +8²) -64 -13 ( x +8)² - 77
<u>Hence</u> <u> the</u> <u> required</u> <u> answer</u> <u> </u> <u>is</u> <u> </u> <u>(</u> <u>x+</u> <u>8</u> <u>)</u> <u>²</u> <u> </u> <u>-</u> <u>7</u> <u>7</u> <u>.</u>

Answer:I think its last one sorry if I am wrong
Step-by-step explanation:
4/10 can be simplified to 2/5 by dividing both the numerator and denominator by 2. Or, you can multiply the numerator and denominator by a number, such as 4, and get 16/40, which is also equivalent of 4/10.
The third option (7-1, 14-2, etc) since we can see that every y is x/7 (7/7 = 1, 14/7 = 2, etc) unlike the others which dont have regular patterns.
