Note that the first function is f(x) = 4 for x less than 2  and for the second function f(x) = -1 for x greater than or equal to 2  

So the limit as x approaches two from the left is 4 and the limit as x approaches 2 from the right is -1.

so looks like you would need the third choice:  4; -1

The scale on a map of Virginia shows that 1 inch represents 45 miles. the actual distance from Richmond, Va, to Washington, D.C.
Talja [164]

Answer: 2.44 inches

Step-by-step explanation:

Since the scale on a map of Virginia shows that 1 inch = 45 miles while the actual distance from Richmond, Va, to Washington, D.C., is 110 miles.

The number of inches that are between the two cities will be represented by x. Therefore,

1/x = 45/110

Cross multiply

45x = 110

x = 110/45

x = 2.44 inches

The Distance between the two cities on the map is 2.44 inches

W=1000M-200 rearrange your make M the subject
Anton [14]

Answer:

M = \frac{w+200}{1000}

Step-by-step explanation:

Given

w = 1000M - 200 ( isolate 1000M by adding 200 to both sides )

w + 200 = 1000M ( divide both sides by 1000 )

\frac{w+200}{1000} = M
