First thing to do is to switch the x and the y and then solve for the new y.  Easier said than done! Here's our equation with the switch: x=2 ^{y} +6.  We need to get that y out from inside that exponent.  This is an exponential equation, and the inverse of an exponential equation is a log equation.  Let's do some simplifying here first: x-6=2 ^{y}.  The 2 is now the base of our log (x-6) so now we have y=log _{2} (x-6), which is the last choice above.

Solve the system of equations below. <br> 5x + 2y = 9<br> 2x - 3y = 15
riadik2000 [5.3K]

Answer:

(3,-3)

y= -3

x= 3

Step-by-step explanation:

5x+2y=9

2x-3y=15

solve the equation

x=9/5-2/5y

2x-3y=15

substitute the value of x into an equation

2(9/5-2/5y)-3y=15

distribute

18/5-4/5y-3y=15

subtract -4/5 to -3

18/5-19/5y=15

subtract 18/5 from both sides

-19/5=57/5

divide both sides by -19/5

y= -3

substitute the value of y into an equation

x=9/5-2/5(-3)

distribute

x=9/5+6/5

add 9/5 to 6/5

x=3

--------

(3,-3)

Suppose you invest $950 at an annual interest rate of 6.5% compounded continuously. How much will you have in the account after
posledela
The correct answer is $1820.

The formula for continuously compounded interest is

A = Pe^(rt), where P is the amount of principal, r is the interest rate expressed as a decimal number, and t is the number of years.  Using our information, we have:

A = 950*e^(0.065*10) = 1819.76 ≈ 1820

julsineya [31]

Answer:

The chi-square null hypothesis for the study that "socioeconomic status is related to smoking behavior" is False

Step-by-step explanation:

The chi-square null hypothesis is false because the chi-square null hypothesis states that no relationship exists on the categorical variables in a population, they are all independent of each other.
