First, -5 x -1 = two negatives make a positive, so 5.

Now, 5 - (-2), two negatives signs make a positive sign, so 5 + 2.

Now, 5 + 2 = 7.

A quantity with an initial value of 980 decays exponentially at a rate of 0.3% every 6 decades. What is the value of the quantit

solong [7]

Answer:

956.73

Step-by-step explanation:

0.3% = 0.003

1-0.003 = 0.997

49/6 = 8 r1 (use 8 because decay is not continuous)

0.997^8 = 0.97625...

0.97625... x 980 ≈ 956.73

Answer:

The correct answer is Option 3: 12y

Step-by-step explanation:

A polynomial term is usually made of a variable and a co-efficient.

Like terms are those terms that have the same variables i.e. x and 44x are like terms.

Given expression is:

$6y-2y+8y$

All the terms have only y which means that all three terms are alike.

The coefficients of like terms are added or subtracted according to their sign.

$6y-2y+8y$ = 12y

Hence,

The correct answer is Option 3: 12y
