Not sure how to solve this

Step-by-step explanation:

You just have to plug the numbers they give you into the equation. For the first one, you have 0 + 5y = 10; 5y = 10; y = 2. For the second one, x + 5(0) = 10; x + 0 = 10; x = 10. And lastly, for the third one, x + 5(6) = 10; x + 30 = 10; x = -20.

Hello, the graph is split in two lines, right?

Go to the first line at the left and move to the right until you reach the end of the line, which is for x = -1,

*** This is the meaning of x tending to

$(-1)^{-}$ ***

which value can you see for the y-axis? $\boxed{-2}$

Now, go to the second line at the right and move to the left until you reach the end of the line, which is for x = -1,

*** This is the meaning of x tending to

$(-1)^{+}$ ***

which value can you see for the y-axis?

$\boxed{-7}$

Thanks

natima [27]

Answer:

Step-by-step explanation:

Suppose the car mileage actually varies slightly with the driving speed of the car

Suppose your car averages 26 miles per gallon on the highway if your average speed is 45 miles per hour,

and it averages 18 miles per gallon on the highway if your average speed is 65 miles per hour.

The driving time for a 2500-mile trip if you drive at an average speed of 54 miles per hour

$= \frac{Distance}{Speed} = \frac{2500 }{45} \\\\= 55.56 hours.$

The driving time for a 2500-mile trip if you drive at an average speed of 65 miles per hour

$= \frac{Distance}{Speed} = \frac{2500 }{65} \\\\= 38.46 hours.$
