Answer:
C, -4
Step-by-step explanation:
slope=change in y/change in x
multiply both sides by 2/5
simplify the right side. 2/5 × 5 = 2 and 2/5 × 10 = 4
bring y to the other side by adding y on both sides
subtract 6 on both sides
so y is -4
Answer: n⁴+10n²x+25x²
Step-by-step explanation:
I don;t know how I can use the binomial squares pattern on Brainly, but I can definitely guide you through the problem.
(n²+5x)² [rewrite this from the squared]
(n²+5x)(n²+5x) [use FOIL to expand]
n⁴+5n²x+5n²x+25x² [combine like terms]
n⁴+10n²x+25x²

Answer:
B. 0.54
Step-by-step explanation:
The mean book rating will decrease
Add all the numbers together:
5 + 5 + 6 + 7 + 7 + 7 + 7 + 8 + 8 + 8 + 9 + 9 + 10 + 10 + 10 + 10 + 10= 136
divide the total with the total amount of numbers
136/17 = 8
Now add all the numbers again WITH the one
5 + 5 + 6 + 7 + 7 + 7 + 7 + 8 + 8 + 8 + 9 + 9 + 10 + 10 + 10 + 10 + 10 + 1= 137
Divide the total amount with the amount of numbers there are
137/18 = 7.61
7.61 < 8
The mean book rating will decrease by 0.39
hope this helps
