Answer:

Jon lost a total of 3 kilograms in these 3 months.

Step-by-step explanation:

Weight that Jon gained in December = 2.2 kilograms

Weight that Jon lost in January = 1.5 kilograms

Weight that Jon lost in February = 3.7 kilograms

Overall Change in his weight = Total Weight he gained - Total weight he Lost

Total weight he gained is 2.2 kilograms as he only gained weight in December. Total weight he lost will be sum of weights he lost in January and February.

So, total weight Jon lost = 1.5 + 3.7 = 5.2 kilograms

Thus,

Total change in Jon's Weight = 2.2 - 5.2 = -3.0 kilograms

This shows that Jon lost a total of 3 kilograms in these 3 months.

Conclusion:

The statement that best describe the total change in his weight is: Jon lost a total of 3 kilograms in these 3 months

Determine whether the function f(x)=4x^3 is even or odd
slega [8]

Answer:

Step-by-step explanation:

Answer:

odd function

Explanation:

   To determine if a function f(x) is even/odd consider the following.

   • If f(x) = f( -x) , then f(x) is even

   Even functions are symmetrical about the y-axis.

   • If - f(x) = f(-x) , then f(x) is odd

   Odd functions have symmetry about the origin.

   Test for even function

   f(−x)=4(−x)3=−4x3≠f(x)

   Since f(x) ≠ f( -x) , then f(x) is not even

   Test for odd function

   −f(x)=−(4x3)=−4x3=f(−x)

   Since - f(x) = f( -x) , then f(x) is odd

   graph{4x^3 [-10, 10, -5, 5]}

You can set up your proportion as \frac{3}{1} * \frac{2}{7} you then multiply across to get \frac{6}{7}. Since this number is less than 1, it's definitely less than 3.

1.1. Which statement explains why the two systems of equations below have the
marin [14]

Answer:

B. The first equation in B is the sum of the equations in A, while the other is obtained

by multiplying the first equation in A by 2.

Step-by-step explanation:

If we add the first two equations that shown in A so

6x + 8y + 2x - 5y = -10 + 12

8x + 3y = 2

Now the first equation in A would be multiplied by 2

So

2(6x + 8y = -10)

12x + 16u = -20

Therefore the correct option is B.
