$D:x\geq-5 \wedge x\geq10\\
D:x\geq10\\\\
\sqrt{n+5}-\sqrt{n-10}=1\\
\sqrt{n+5}=1+\sqrt{n-10}\\
n+5=1+2\sqrt{n-10}+n-10\\
2\sqrt{n-10}=14\\
\sqrt{n-10}=7\\
n-10=49\\
n=59$

Can someone explain how to get to answer B?

sesenic [268]

Yo have to find the distance between point L and point M. First, you have to do the x values. 1 - -3 = 4. Then, you subtract the y values. -2 - 4 = -6. Next, you add the found numbers to the x and y of the midpoint (m). Leaving 1 +4=5 and -2 + -6 = -8.

The population of Portland Oregon has recently grown to more than 500,000. What is the order of magnitude for the number of peop

miss Akunina [59]

Answer:

Order is 6

Step-by-step explanation:

The population of Portland Oregon has recently grown to more than 500,000.

The order of magnitude for the number of people in Portland means the power of 10. It means that we need to write 500,000 in form of 10 to the power. So,

$P=500,000$

It contains 6 zeroes. It means,

$P=5\times 10^6$

So, the order of magnitude for the number of people in Portland is 6.
