Answer: 1
Step-by-step explanation:
Y2 - Y1 / X2 - X1
-2 - 1 = -3
-1 - -4 = 3
-3/3 = 1
Step-by-step explanation:
al nth term:
numerator:

denominator:

so nth term :

b). 1; 11; 27; 49
first difference: 10; 16; 22
second difference :6
formula for 1st difference:3a+b
formula for 2nd difference:2a
Therefore:
2a=6
a=3
3a+b=10
sub in a
3(3)+b=10
9+b=10
b=1
sub into quadratic formula






So Tn:

Answer:
B
Step-by-step explanation:
3% = 3/100
So we can eliminate the first answer.
The proportions have to match each other so the number nine should be above and thus the x has only the option of being under it.
As a result, we eliminate the third answer and remain with one reasonable answer
Let the number = x
11x is 11 times the number. You are to take 6 less than this. Be careful how you read six less. It means the 6 is subtracted from the 11x
11x - 6 This is what you finally get.
Answer:
x = -48
