x2 + 8x + y2 + -2y = 64
Reorder the terms:
8x + x2 + -2y + y2 = 64
Solving
8x + x2 + -2y + y2 = 64
Solving for variable 'x'.
Reorder the terms:
-64 + 8x + x2 + -2y + y2 = 64 + -64
Combine like terms: 64 + -64 = 0
-64 + 8x + x2 + -2y + y2 = 0
The solution to this equation could not be determined.</span>
Answer: 9
Explanation: you would use PEMDAS to solve the algebraic expression first by doing parentheses so subtract 8 and 7 which leaves you with 4 + 1 times 6-1. You would then multiply 1 into 6 which would leave you with 4 + 6 - 1 which you would then sum up 4 and 6 which leaves you with 10-1 which would give you the answer of 9
So the answer would be 9
Hope this helps!

Answer:
3.6
Step-by-step explanation:
9-0.2(4-7)^3
9-0.2(-3)^3
9 -0.2 (-27)
9-5.4=3.6
Here we are given how much work is done in a fix time interval
then they ask to find the rate of doing the work .
in such problem we can find the rate of doing a work by using the formula :
amount of work done
--------------------------------------------------- = work done in unit time
Time taken to do that amount of work
In 40 minutes number of pages she reads = 50
In 1 minutes number of pages she would be reading = 50 /40
= 5/4 page
Answer 5/4 page .
