After every 2 years, a certain computer loses half of its value. Let the initial price of the computer be x .

So after 2 years, the price reduce to half of its price , that is 0.5x .

After 4 , years, the price reduce to half of its price , that is 0.25x .

After another 2 years, that is after 6 years, the price reduce to half, that is 0.125 x .

Therefore after 6 years, the price of the computer worth 12.5% of the initial value .

Find the slope of the line containing the two points.<br><br> (2,5),(-3,-2)<br><br> Please show work
HACTEHA [7]

Answer:

7/5

Step-by-step explanation:

To solve this problem we will use the formula to find the slope of a line given two points (x₁, y₁), (x₂, y₂)

The formula is:

m= \frac{y{_2} -y_{1}}{x_{2}-x_{1}  } \\\\

So, we're going to use the points (2,5), (-3, -2) in this formula.

m= \frac{-2-(5)}{-3-(2)} \\m=\frac{-2-5}{-3-2}\\m=\frac{-7}{-5} \\m=\frac{7}{5}

Therefore, the slope is 7/5

Which of the following is not a function?
rusak2 [61]
Answer: B

Number on the left: x-value
Number on the right: y-value

If there are 2 y-values for one x-value it is NOT considered a function.

For instance in the answer:

(2,3), (2,4), (3,3), (3,4)

You can clearly see that the x-values (2 & 3) repeat more than once; therefore, it is NOT a function.

On the other hand if you have 2 DIFFERENT x-values for the same y-value it IS A FUNCTION.

For ex D: (2,4), (3,4), (5,4), (6,4)

As you can see there are 4 DIFFERENT x-values with same y-value; therefore it is A FUNCTION

To make it easier:

If x-values appear more than once = NOT A FUNCTION

If x-values appear only ONCE = FUNCTION

Remember: y-values are ALLOWED to repeat

I hope this helps. If you have any questions please let me know in the comments.
