Answer:

-0.5 is not a solution

2 is a solution

Step-by-step explanation:

To check if something is a solution of the equation, you need to substitute the value in place of the variable

15 + 2y = -12 - 4y

15 + 2(-0.5) = -12 - 4(-0.5)

15 - 1 = -12 + 2

14 ≠ -10 ∴ -0.5 is not a solution

5 - 2(3x + 5) = 3 - 10x

5 - 2[3(2) + 5] = 3 - 10(2)

5 - 2(6 + 5) = 3 - 10(2)

5 - 12 - 10 = 3 - 120

-17 = -17 ∴ 2 is a solution

dlinn [17]

Assuming uniform distribution and independence, then
P(1st number less than 8 and 2nd number less than 8) = 
P(1st number less than 8)*P(2nd number less than 8) = 
(7/12)*(7/12) = about 34%

Select the true statement about the series, ¾ + 7/8 + 11/12 + 15/16…

Luden [163]

$\dfrac34+\dfrac78+\dfrac{11}{12}+\dfrac{15}{16}+\cdots=\displaystyle\sum_{n=1}^\infty\frac{4n-1}}{4n}$

The $n$ th term in the series is

$\dfrac{4n-1}{4n}=1-\dfrac1{4n}$

which means for large $n$ , the series behaves asymptotically similar to the series

$\displaystyle\sum_{n=1}^\infty1$

which diverges, so the answer is (B).
