Answer:

The answer is -15.

Step-by-step explanation:

1. 2x - 1

2. 2(-7) - 1

3. (-14) - 1

4. -15

By plugging in our x value, we are able to use PEMDAS to  multiply 2 and the value of x and then, we subtract 1 from the value we got from step 3 to get -15.

The solid lines directly leading to a number will be that number, for instance, chocolate is 50.

P varies inversely with x. If P = 12 when x = 4, find the value of P when x = −48.
Alla [95]

Answer:

P = - 1

Step-by-step explanation:

Given P varies inversely with x the the equation relating them is

P = \frac{k}{x} ← k is the constant of variation

To find k use the condition P = 12 when x = 4

12 = \frac{k}{4} ( multiply both sides by 4 )

48 = k

P = \frac{48}{x} ← equation of variation

When x = - 48, then

P = \frac{48}{-48} = - 1
