Point slope form:

m=slope
(x1,y1)
First we need to find the slope using the slope formula:

Given the two coordinates:
<span>(1, 9) and (−1, 11)
Plug them into the slope formula:
</span>

Simplify:

<span>
Now we know that:
m=-1 and the (x1,y1) would be </span><span>(1, 9)
</span>
Now we simply plug in the info:
Final answer: y − 9 = −(x − 1)
I don’t know if you’ve ever heard of the amazing device known as a calculator but the answer is 1,188
Answer:
D. 88
Step-by-step explanation:
if you add the given numbers up (equals 100) them subtract it from 540(the degrees of a Pentagon) you get 440. then divide that by 5 (number of xs left) you get 88. You can plug in 88 for x and check but I already did, I hope this helps you lemme know if it does :)
Total mass = 6.08 x 10^23 * 1.67 x 10^-24 = 1.01536
Answer:

Step-by-step explanation:

Making denominator same in first bracket we get


Dividing 6 by 3 we get 2

using distributive law

Hence this is our answer
