Which student solved their equation incorrectly? (ANSWER QUICK)

What number is not part of the domain of f(x)= 3/ x+5 (3 over x + 5)

nignag [31]

-5, you never want the denominator to equal zero or else it doesnt exist!

x+5=0
x=-5

Solve for g: 4g/14 - 3/7 - g/14 = 3/14

Luden [163]

Answer:
g = 3

Explanation:
To solve for g, we will need to isolate the g on one side of the equation.
This can be done as follows:
 $\frac{4g}{14} - \frac{3}{7} - \frac{g}{14} = \frac{3}{14}$ 

1- multiply all terms by 14 to get rid of the fraction:
4g - 6 - g = 3

2- Combine like terms:
4g - g = 3 + 6
3g = 9

3- Isolate the g:
 $\frac{3g}{3} = \frac{9}{3}$

g = 3

Hope this helps :)

In 2000, the population of a country was approximately 6.31 million and by 2069 it is projected to grow to 12 million. Use the

mestny [16]

Answer:

Step-by-step explanation:

This is your exponential growth function for population:

$A=A_{0}e^{kt}$ and these are your initial conditions with the year 2000 being t = 0

(0, 6.31) and (69, 12)

We will use those values to find the equation that models this population growth. In the coordinates, the first number is the time in years, t; the second number is the population after a certain time t goes by. In other words, the second number represents the A in our model. Using those values from the first set of coordinates will help us solve for A₀:

$6.31=A_{0}e^{k0}$ which is basically e raised to the power of 0 which is equal to 1, so we get from that first set of coordinates that A₀ = 6.31
