Answer:
r equals start fraction cap a minus p over p t end fraction
Step-by-step explanation:
Subtract the term non containing r, then divide by the coefficient of r.

Using proportions, it is found that Talisa's error was at calculating the cost per minute of the game.
In the function:
- The input is x, which is the number of minutes.
- The output is f(x), which is the cost of playing the game for x minutes.
Talisa's expression is given by:

The cost of using a game facility is <u>$1 for every 12 minutes</u>, hence, the cost per minute is:

And the correct expression for the cost is:

Hence, it can be seen that Talisa's error was at calculating the cost per minute of the game.

9m + 6 would be the answer
Answer: y = -2x - 5
Step-by-step explanation:
The condition for parallelism is that m1 = m2 ie, the gradient of the two lines must be equal.
from the equation given,
y = -2x + 8, m1 = -2, therefore m2 = -2. Since the two line passes through the coordinate of (-1, -3 ) , we substitute for x and y in the equation of a line
y = mx + c to get the value of , the y - intersect.
-3 = -2 x -1 + c
-3 = 2 + c
solve for c
c = -3 - 2
c = -5.
now , to have the equation of the line , we put c = -7 into the equation
y = mx + c
y = -2x - 5
Therefore the equation of the line parallel to the line
y = -2x + 8 is
y = -2x - 7
