There are some roses, lilies, and orchids in the vase. the number of roses is twice the number of lilies and the number of orchids is 5 more than the number of roses. if the total is 45, find the number of each type of flower

Step-by-step explanation:

Let's say R is roses, L is lilies, and O is orchids.

R = 2L

O = R + 5

R + L + O = 45

Let's substitute the second equation into the third:

R + L + (R + 5) = 45

2R + L = 40

Now substitute the first equation:

2(2L) + L = 40

4L + L = 40

5L = 40

L = 8

Therefore:

R = 2L = 16

O = R + 5 = 21

There are 16 roses, 8 lilies, and 21 orchids.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
