Answer:

While the coordinates would be a solution to the first equation, they are not for the second equation, so the answer to your question is no.

Step-by-step explanation:

All you have to do is substitute the coordinates into the x and y values.

(2)-2(-1) = 2+2 = 4 We can tell that the coordinates worked for the first equation. Lets see if it works for the second, as well.

3(2) + (-1) = 6-1 = 5 Unfortunately, the coordinates were incorrect for the second equation.

Shirley wants to find an estimate for the number of bees in her hive.
Illusion [34]

The estimate for the total number of bees in her hive is 190 bees

<h3>How to find the total estimate of the bees ?</h3>

She catches 90 of the bees on Monday and she puts mark on each bees and return them to her hive.

On Tuesday she catches 120 of the bees. She find out that 20 of the bees has been marked.

This means only 100 bees have not been marked on Tuesday.

Therefore, the total number of bee in her hives is as follows:

total number = 90 + (120 - 20)

total number = 90 + 100

total number = 190 bees

I need some help please!
adell [148]

Answer:

8 seconds

Step-by-step explanation:

lets first start by plugging in 1024 into initial height

h(t) = -16t^2 + 1024

I would find a Greatest Common Factor (GCF) first

-16(t^2 - 64)     If this is new just think that if you multiply -16 by t squared and -64 you will come back to the original equation

But now we notice that T squared -64 can be factored with the difference of perfect squared method

so we will get -16(t-8)(t+8)

So to get the answers we will set everything equal to 0

-16t =0

t =0 this is the time that the penny was thrown

t-8 = 0

t = 8 the is the time the penny hit the ground

t+8 =0

t= -8 This is an extraneous solution or a solution that doesn't make sense so we just disregard the solution.
