Answer:
b = 2 or b = 7
Step-by-step explanation:
b/(b-7) - 2/b = 7/ (b-7)
b * b - 2(b - 7) = 7 * b
b^2 - 2b + 14 = 7b
b^2 - 9b + 14 = 0
(b - 2)(b - 7) = 0
b - 2 = 0; b = 2
b - 7 = 0; b = 7
Answer
b = 2 or b = 7
Answer:
A. Yes (True) B. Yes (True)
Step-by-step explanation:
The first some is true because the square root of 50 is between 6 and 7, which IS greater than 5
The second one is false because the square root of 3 is between 1 and 2, which which could be some of the a+v side of the triangle.
Hope this helped
Answer:
see explanation
Step-by-step explanation:
Note there is a common difference d between consecutive terms, that is
d = 7 - (- 3) = 17 - 7 = 27 - 17 = 10
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 3 and d = 10, thus
= - 3 + 10(n - 1) = - 3 + 10n - 10 = 10n - 13 ← explicit formula
The recursive formula allows a term to be found by adding d to the previous term, thus
= + 10 ← recursive formula
Answer:
x = 7
Step-by-step explanation:
5x = -2x + 49
5x + 2x = 49
7x = 49
x = 49 ÷ 7
x = 7
