Answer:
Option 2 is correct.
Step-by-step explanation:
We have been provided a table of values of an exponential function and we are asked to find out the decay factor of the function.
Upon looking at our table we can see that every time x increases by one our y value remains one-third of the previous value.
To find out decay factor we will subtract 1/3 from 1.
Therefore, decay factor of the exponential function is 
and option 2 is correct choice.
We can do the elimination method to find the solution for this problem. The elimination method involves adding the two equations together to get rid of a like term.
x + 2y = 7
+ x - 2y = -1
—————————
2x = 6
Now that we eliminated 2y because they cancel out, we are left with 2x = 6. Divide both sides by 2 in order to get x.
The answer is: x = 3.
Now that we know the numerical value of x, all we have to do is plug x into either system of equation in order to find the numerical value of y.
x + 2y = 7
3 + 2y = 7
2y = 4
y = 2
The solution to the problem is (3, 2).
Answer:
Step-by-step explanation:
Given
Ferret:
Labrador Retriever
Required
Determine the slope
Represent the given as x or y
Taking the weight as explanatory variable;
We have:
x = 2.1; y = 3.4
x = 7.5; y = 70
Slope is calculated as:
<em>Hence, the slope is 12.33</em>
Answer:
16x^2 -3x-4
Step-by-step explanation:
Im guessing the -4 is subtracting from 3x so that's the awnser above. But if it is a exponet then your answer would be: -16x^4+2-3/x^4 the slash is the same as dividing.

To find the answer to this problem, all you have to do is divide the price of the product by the number of ounces. So to find the price per ounce of the large can of tomato soup, you divide 4.40 by 22, which equals .20 cents per ounce. For the smaller can, you divide 1.80 by 10, which equals .18 cents per ounce. So the smaller can has the best price per ounce.
