Option fourth "−48; velocity decreases at rate of 48 miles per hour as the time increases" is correct.

<h3>What is the slope?</h3>

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

\rm m =\dfrac{y_2-y_1}{x_2-x_1}

We have a function:

v(t) = 352 − 48t

The above function represents the speed of a plane that is landing in the sky.

The function is a linear function.

On comparing with:

y = mx + c

v(t) = -48t + 352

m = -48

-48 is the slope and it representing velocity decreases at rate of 48 miles per hour as the time increases.

Thus, option fourth "−48; velocity decreases at rate of 48 miles per hour as the time increases" is correct.

Solve the system of equation <br> Y=4x-11<br> Y=x+13<br><br> X=<br><br><br> Y =
Phoenix [80]

Answer:

(8,21)

Step-by-step explanation:

Since both equations equal y, set both equaitions equal to each other

and solve for x

4x-11=x+13 , subtract x from both sides

3x-11=13, add eleven to both sides

3x=24, divide both sides by 3 to get x alone

x=8

Substitute x=8 into either equation to solve for y

y=4(8)-11

y=32-11

y=21

Select the correct choices to complete the sentence. Three drivers competed in the same fifteen drag races. The mean and standar
sweet [91]

Answer:

<h2> Driver B has the fastest race time</h2>

Step-by-step explanation:

From the options presented, driver B has the fastest typical race time because he recorded the smallest time taken to complete an individual race.

Also from the standard deviation given (3.96) for driver B, it shows that the individual time spread from the standard deviation is minimal and that the driver maintained a fairly consistent time of race throughout the racing period.
