Answer:

C. 13

Step-by-step explanation:

Put 4 where y is in the equation and do the arithmetic.

$p(y)=\dfrac{4y}{2}+5\\\\p(4)=\dfrac{4(4)}{2}+5 = \dfrac{16}{2}+5=8+5\\\\\boxed{p(4)=13}$

Find the solution of the system of equations. 3x-8y = 19<br>3x + 5y = -46<br>

sattari [20]

(-7,-5)

Step-by-step explanation:

3x-8y = 19

minus

3x + 5y = -46

0x - 13y = 65

- 13y = 65

÷-13

y = - 5

Substitute y = - 5 into one of the functions:

3x-8y = 19

-8 x - 5 = 40

3x + 40 =19

-40

3x. = - 21

÷3

x= - 7

Solution is (-7,-5)

Hope this helps!

In the year 2005, a total of 750 fish were introduced into a man made lake. The fish population was expected to grow at a rate o

Butoxors [25]

Answer:

In 2050 fish population is 27000

Step-by-step explanation:

Exponential change can be modeled by,

$F=F(0)+x^{n}$

Where $F(0)$ is the initial value of 750, $x$ is the rate of change. It is greater then 1 when there is growth and less then 1 when there is decay. and $n$ is the number of time periods.

The rate of change in percentage is 8.3%

That means, after 1 year fish will become 108.3 for 100 fish.

Then $x=\frac{108.3}{100}$

$x=1.083$

Difference of years is, $n=2050-2005=45$

Then, $F=750+$ $1.083^{45}$

$F=27000$

So, the fish population in 2050 is 27000

When 12 is decreased by twice a number, the result is -14. Find the number.

Talja [164]

Answer:

-13

Step-by-step explanation:

Twice a number is 2h (h is the variable) so the equation is 12-2h=-14 and - 13 times 2 is -26 so the equation is now 12-26=-14
