Find the distance between the points (-4, -5) and (3, -1).
Dmitry [639]

Answer:

Square root of 65 or 8.06  to the nearest hundredth.

Step-by-step explanation:

We use the Pythagoras Theorem ( Distance Formula):

This = √ [( x2 - x1)^2 + (y2 - y1)^2 ]

= √ [( 3 - -4)^2  + (-1 - -5)^2]

= √ (7^2 + 4^2)

= √65

= 8.06 to the nearest hundredth.

Answer:

260 + 20x

How long is a job for which the two companies' costs are the same?

380 + 14x = 260 + 20x

380 - 260 = 20x - 14x

120 = 6x

20 = x
