Compounds a and b are used in an experiment.

the equation y=500(0.5)x

represents the remaining amount of compound a, in grams, after x hours. the table shows the remaining amount of compound b.
time (h) grams of b
1 200
2 100
3 50

what is the positive difference in the initial amount of each compound?

Positive Difference = 100 grams

Step-by-step explanation:

We have two compound A and B

Compound A:

We have to find initial value of compound A. For initial value, we will put x=0 into equation.

Initial amount

Initial amount of compound A = 500 grams

Compound B:

Time (h)           :    1         2        3

Compound B  : 200    100     50

First we have to make the function for compound B.

According to table we can see amount becomes 50% of previous value every hour.

In 1 hour, Compound B = 200 grams

Initial amount should be 50% more than 200.

Initial amount of Compound B = 400 grams

We need to find positive difference of initial amount of compound  A and B

Difference = 500 - 400

Positive Difference = 100 grams

Hence, The positive difference of initial amount of Compound A and Compound B is 100 grams.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
