Transposition

Transposition is a method to isolate the variable to one side of the equation and everything else to the other side so that you can solve the equation.

Algebraic equations can be solved using the Law of equations. The Law of equations states that whatever you do on one side of an equation, you must do on the other side as well.

I have no idea what to do. PLS HELP

Answer:

$\textbf{Option C}\\$

Step-by-step explanation:

$\textup{You have to substitute values of x from the table and see if it satisfies the given condition.}\\\textup{For example in option A, $(-2,-2)$ is the point given.}\\\textup{Substitute $x = -2 $ in $y = -x^2 + 3x $}\\\textup{We get $y = -10 \ne -2$. Eliminate option $A$ and $B$ from this.}\\$

$\textup{Now we will check for $x = 1$ as the values of $y$ differ in options $C$ and $D$.}\\$i.e., $ \textup{For} $x = 1, y = - {1}^2 + 3(1) $\\$\implies y = 2 \ne 4$, \textup{eliminating Option $D$.}\\\textup{Also substitute other values for $x = -1, 0, 2$ and the answer can be verified.}\\\textup{\textbf{Hence, option $C$ will fit this function.}}$

Tems11 [23]

Answer: The answer is (C) cannot be determined.

Step-by-step explanation: Given that Jennifer and James planned to drive from home to the stadium to watch a football match on a rainy day. The distance from home to stadium is 30 miles.

Also, when they reached half the distance, i.e., they covered 15 miles, then they realised that they forgot the tickets, because of which they had to drove back to home and then again to the stadium.

Therefore, the total distance they covered = 15 + 15 + 30 =60 miles, i.e., they had to cover double the distance from home to the stadium.

Finally, it is given that the game was fantastic with final score of 21 to 20. This information has no relation to the original question which was about the distance, not score and we cannot find out score from the given information.

Thus, the correct option is (C) cannot be determined.

At 9 AM there are 37 bacteria in a dish and they start doubling every 15 minutes. At t = 274 minutes an

givi [52]

Answer:

5,035,041

Step-by-step explanation:

Exponential growth:

$y = a(1 + r)^{x}$

y = future amount

a = initial amount

r = growth rate

x = number of periods

Part A: growth at the rate of doubling each 15 minutes for 274 minutes

Each period is 15 minutes.

a = 37

x = 274/15 = number of periods

r = 100%

$y = 37(1 + 1)^{\frac{274}{15}$

-------------------------------------------------------------------------------------

Exponential decay:

$y = a(1 - r)^{x}$

The growth takes place from 9 AM for 274 minutes, or 4 hours and 34 minutes, until 1:34 PM. The decay goes from 1:34 PM to 7 PM, or 5 hours and 26 minutes, or 326 minutes

Part B: decay at the rate of 6% each 24 minutes for 326 minutes

$y = 37(1 + 1)^{\frac{274}{15}}(1 - 0.06)^{\frac{326}{24}}$

$y = 5035041$
