Hello!

The graph, (2/5)^x is an exponential function.

Since there is not a negative symbol in the front of the function, options A and B are incorrect.

For option 3 to be correct, there would need to be a negative symbol in front of the exponent, x.

So therefore, the answer option 4. (Also, I'll post a graph. :))

If P = 2l + 2w, the formula to find w is . If P is 30 units and l is 10 units, w is units.

Helen [10]

Answer:

If P is 30 units and l is 10 units, w is 5 units

Step-by-step explanation:

1. Let's check the information given to resolve the question:

P = 2l + 2w

If P is 30 units and l is 10 units, w is units

2. Replacing with the values:

P = 2l + 2w

30 = 2 (10) + 2w

30 = 20 + 2w

-2w = 20 -30 (Subtracting 2w and - 30 to both sides)

-2w = - 10

2w = 10 (Multiplying by - 1 at both sides)

w = 5 (Dividing by 2 at both sides)

If P is 30 units and l is 10 units, w is 5 units
