The high school soccer team can have no more than 27 players. Solve an inequality to determine how many players can make the tea

Dvinal [7]

Answer:

The answer is $x\leq 9.$

Step-by-step explanation:

Now, to find the number of players to make the team by solving an inequality.

Let the number of players that can make team be $x.$

Total number of players high school soccer team can have = 27.

Already players chosen by coach = $18$ .

According to question:

$x+18\leq 27$

<em>Subtracting both sides by 18 we get:</em>

$x\leq 9.$

Therefore, the answer is $x\leq 9.$

Find the x and y intercept for -2x-5y=30

Ahat [919]

Answer:

see below

Step-by-step explanation:

-2x-5y=30

To find the x intercept, set y =0 and solve for x

-2x-5*0=30

-2x = 30

Divide each side by -2

-2x/-2 = 30/-2

x =-15

To find the y intercept, set x =0 and solve for y

-2*0-5y=30

-5y = 30

Divide each side by -5

-5y/-5 = 30/-5

y = -6

A bird species in danger of extinction has a population that is decreasing exponentially (A = A0e^kt). Five years ago, the popul

Natalija [7]

Answer:

It'll take approximately 34 years from today.

Step-by-step explanation:

in order to solve this problem we first need to find the rate of change, "k", to do that we will use the given information where the population was 1400 five years ago and its now 1000. Applying this data to the equation gives us:

$A = A_0*e^{k*t}\\1000 = 1400*e^{5*k}\\1400*e^{5*k} = 1000\\e^{5*k} = \frac{1000}{1400}\\ln(e^{5*k}) = ln(\frac{1000}{1400})\\5*k = ln(1000) - ln(1400) \\k = \frac{ln(1000) - ln(1400)}{5} = -0.06729$

We now know the value for "k", we can estimate how many years it will take for the bird population to dip below 100. We have:

$100 = 1000*e^{-0.06729*t}\\e^{-0.06729*t} = \frac{100}{1000}\\ln(e^{-0.06729*t} = \frac{1}{10}\\-0.06729*t = ln(0.1)\\t = -\frac{ln(0.1)}{0.06729} = 34.22$

It'll take approximately 34 years from today.
