Answer:
y-7=-2(x+3)^2
Step-by-step explanation:
Vertex Form
y = a(x-h)^2 + k
move the 7 by adding it to both sides in order to get it into vertex form.
Answer:
<h2>n = 72</h2>
Step-by-step explanation:
![\frac{n}{3} - 7 = 17](https://tex.z-dn.net/?f=%20%5Cfrac%7Bn%7D%7B3%7D%20%20-%207%20%3D%2017)
Using the addition property add 7 to both sides
That's
![\frac{n}{3} + 7 - 7 = 17 + 7 \\ \frac{n}{3} = 24](https://tex.z-dn.net/?f=%20%5Cfrac%7Bn%7D%7B3%7D%20%20%20%2B%207%20-%207%20%3D%2017%20%2B%207%20%5C%5C%20%20%5Cfrac%7Bn%7D%7B3%7D%20%20%3D%2024)
Next multiply both sides by 3 to eliminate the fraction
That's
![3 \times \frac{n}{3} = 24 \times 3](https://tex.z-dn.net/?f=3%20%5Ctimes%20%20%5Cfrac%7Bn%7D%7B3%7D%20%20%3D%2024%20%5Ctimes%203)
We have the final answer as
<h3>n = 72</h3>
Hope this helps you
Answer:
I will answer this in English.
a) here you written 208 = (2^6)*3, while in the table you can see 5 times the number 2 and 2 times the number 3, this means that:
208 = 2^5*3^2
then we would have:
√208 = √(2^5*3^2) = 3*2*√2 = 6*√2
b) This time is correct that:
1568 = 2^5*7^2
but the simplification in the square root is not correct. (√(2^5) is not equal to 2^2)
as √(2^5*7^2) = √(2*2^4*7^2) = 2^2*7*√2 = 4*7*√2 = 28*√2
They are all 200 bigger than each other y = x + 200
