<h3>Question:</h3>
find the slope (-8,10) (8,15)
<h3>Answer:</h3>
m = 
<h3>Step-by-step explanation:</h3>
Use the slope formula 
(x2,y1) = (-8,10) , (x2,y2) = (8,15)
m = 
m =

Answer:

Step-by-step explanation:
you have to use the midpoint formula which is

so you plug your numbers in

Add the tops

if possible simplify
and that is your answer

(hope this helps can I pls have brainlist (crown) ☺️)
Step-by-step explanation:
7^8 x 7^3 x 7^4 / 7^9 7^5
= 7^(8+3+4) / 7^(9+5)
= 7^15 / 7^14
= 7^(15-14)
= 7.
When the bases of the numbers are the same when multiplying numbers with exponents, you can just add the exponents like so:
7^8 x 7^3 x 7^4= 7^15
Now, look at the rest of the simplified equation and do the same to the denominator:
7^15 / 7^9 x 7^5 ⇒ 7^15/ 7^14
When the bases are the same in the fraction, you are allowed to subtract the exponents. This will lead you to the simplified answer = 7^15-14 = 7^1 = 7
