Answer:
The solution is given below:
Step-by-step explanation:
As we know the value of k and r so the equation will be
Answer: 72 cars.
Step-by-step explanation:
Let be "x" the number of toys that Moby had to start with.
According to the information given in the exercise, Moby sold half his toy car collection. This can be represented with the following expression:
Then he bought 12 more cars, giving a total amount of 48 toy cars.
Therefore, the equation that represents this situation is the equation shown below:
Now you must solve for "x" in order to find its value.
You get that this is:
Answer:
9x^2 25x+14
Step-by-step explanation:
using FOIL:
(x+2)(9x+7)
9x^2 +7x + 18x +14
9x^2 25x+14
The function is y = 640/ 4^x and the graph decreases exponentially from 640 (for x =0) and asymptotically approacdhes zero (when x becomes larger and larger). This is an exponential decay.
Answer: the last option of the list. The graph will show exponential decay
Answer:
126 square miles
Step-by-step explanation:
So I just draw a grid and mark the thingies (sorry my math vocabulary is not very good)
So you get a rectangle that is 5x9 if you connect the dot thingies and 9 square units is 14 square miles and 9x14=126. Using a coordinate grid makes it easier to visualize what you’re doing
