Mathematics
1 answer:
ella [17]2 years ago
5 0

Answer:

Step-by-step explanation:

This is modeled after an exponential function which, at its simplest, is

y=a(b)^x where, for us and in this particular situation, y is the final height, a is the initial height, b is the rate of growth or decline, and x is the number of bounces. We know the initial height is 20, but we need to find the rate of decline. Rewriting the formula to model a rate of decay or decline is

y=a(1-r)^x, or more closely related to our circumstances:

H=20(1-.8)^n and simplifying that a bit:

H=20(.2)^n, choice D.

Each bracelet is $5, this can be represented as 5b. (Where b is number of bracelets)

Each necklace is $8, this can be represented as 8n. (Where n is number of necklaces)

We know that the total money raised needs to be at least $100, but it can also be more than that.

So we know that 8n+5b will be greater than or equal too 100.

8n+5b ≥ 100

qaws [65]

Answer:

You aren't supposed to add 3k

Step-by-step explanation:

3k is a positve number. So instead of adding you have to subtract to be able to move on. Correct way shown below. Once you get this step wrong your answer will also be wrong. At the end you also need to divide

19-2k= 3k-1

  -3k  -3k

19-5k= -1

-19      -19

 -5k= -20

-5/-5= -20/-5

    k=4
