The vertex form: y = a(x - h)² + k
y = x² - 6x + 7 = x² - 2x · 3 + 3² - 3² + 7 = (x - 3)² - 9 + 7 = (x - 3)² - 2
Answer: y = (x - 3)² - 2
Used: (a - b)² = a² - 2ab + b²
Answer:
Step-by-step explanation:
Actually, you can't. You could multiply the numerator and denominator of each 4/3 and 3/3 by 5, obtaining:
5(4) 5(3)
------ and --------
5(3) 5(3)
but this result has little practical value. 4/3 and 3/3 could be combined immediately, obtaining 7/3, if that's what you want to do, as the fractions already have the same denominator (3).
Remember the rule, if the number is a decimal, it should be multiplied by 10^-n.
Formula = a * 10^-n
0.0008235 in scientific notation
=> 8.235 * 10^-n
There are 3 0s from the left side of the numbers and going to the decimal point.
<span>So, we're</span> gonna move 3 to the left
=> 8.235 * 10^-3.
Negative because it is a decimal number.
