In a set of ordered pairs for which the x-coordinates increase by a constant amount, which identifies the set as representing exponential decay?
A. The y-coordinates decrease by a constant amount
B. The y-coordinates decrease by a constant negative factor
C. The y-coordinates decrease by a constant positive factor between 0 and 1
D. The y-coordinates are always negative and decreasing

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
