You just average the x and y. So for x it is (3+-5)/2 = -1 and for y it is (8+-1)/2=3.5.
The midpoint is (-1,3.5). See picture for a graphical explanation.
The simplified difference of the polynomials (a³b+9a²b²-4ab⁵) and (a³b-3a²b²+ab⁵) is (12a²b²-5ab⁵).
<h3>What are Like terms?</h3>
Like terms are those terms that are having the same variables, also the variables are of the same order as well.
for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.
Let's simplify the two of the given polynomials, therefore, find the difference between the two given polynomials.

Hence, the simplified difference of the polynomials (a³b+9a²b²-4ab⁵) and (a³b-3a²b²+ab⁵) is (12a²b²-5ab⁵).

Answer:
-65
-61
20ab - 3bc - 3ac
Step-by-step explanation:
1.) Find the sum of 72−104+5and -32+ 4-10.
72 - 104 + 5 = - 27
- 32 + 4 - 10 = - 38
Sum of (-27 and - 38) = - 27 + (-38) = - 65
2.) What should be added to 32+32+3 to get 3+3
32 + 32 + 3 = 67
3 + 3 = 6
67 + x = 6
x = 6 - 67
x = - 61
3.) Subtract the sum of 12ab –10bc –18ac and 9ab +12bc + 14ac from the sum of ab + 2bc and 3bc –ac
(12ab –10bc –18ac) + (9ab +12bc + 14ac)
12ab + 9ab - 10bc + 12bc - 18ac + 14ac
= 21ab + 2bc - 4ac
(ab + 2bc) + (3bc - ac)
ab + 2bc + 3bc - ac
ab + 5bc - ac
(21ab + 2bc - 4ac) - (ab + 5bc - ac)
21ab + 2bc - 4ac - ab - 5bc + ac
21ab - ab + 2bc - 5bc - 4ac + ac
20ab - 3bc - 3ac
Answer:
x = 9.6
x = - 2.6
Step-by-step explanation:

Ignore the before the ± it wouldn't let me type it correctly.
x² - 7x - 25 = 0
a = 1
b = - 7
c = - 25





Two separate equations




x = 9.6


x = - 2.6
Y = 8x + 6
have a good day!! :/)
