Answer:
B
Step-by-step explanation:
Let the number = x
2/5 (x - 1)
<
3/5 (x + 1)
2/5 (x - 1 ) < 3/5(x+ 1) Multiply both sides by 5
2(x - 1) < 3 ( x + 1) Remove the brackets.
2x - 2 < 3x + 3 Add 2 to both sides
2x < 3x + 5 Subtract 3x from both sides
2x - 3x < 5
- x < 5 Here's the tricky part . Divide by - 1
x > -5 Notice what happened. The < become > That happens because you have divided (or multiplied) by a negative number.
The original question 2/5 (x - 1 ) < 3/5(x+ 1) was graphed. The red part is every value that satisfies the inequality. You should be using a y and x together to find a more suitable answer using this program. But if you just look along the x axis, you will see that the < has been turned around.
B The second one from the top.
The function f(x) is shown in the graph is (a) an exponential function
<h3>How to determine the function type?</h3>
From the graph, we can see that:
- The function starts from a base
- It then increases, exponentially
Only exponential functions have the above features
Hence, the function f(x) is shown in the graph is (a) an exponential function

The minimum accepted mass is 18.25 - 0.36 = 17.89 oz
The maximum accepted mass is 18.25 + 0.36 = 18.61 oz
So the range of rejected mass is x < 17.89 U x > 18.61
Answer:
No, it is not.
Step-by-step explanation:
This is not proportional, however, it is linear
