Step-by-step explanation:

3 hour and 15 min = 3.25hr.

1 hour = 56 miles

=> 3.25 hours = 56 * 3.25 = 182 miles.

What is the slope of the line passing through the points

Bingel [31]

Hello!

Answer:

$\boxed{2}$

Step-by-step explanation:

$Slope=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}$

$\frac{1-(-5)}{4-1}=\frac{6}{3}=2$

Therefore, the slope is 2, which is our final answer.

Hope this helps!

Have a nice day! :)

Thank you!

How does the graph of y= -(2x+6)^2+3 compare to the graph of a parent function

raketka [301]

Here the list of the transformations applied to the parent function, and their effect:

$x^2 \to (2x)^2=4x^2$ . This causes a horizontal compression of factor 4.
$(2x)^2 \to (2x+6)^2= 4(x+3)^2$ . This causes a horizontal translation, 3 units to the left.
$(2x+6)^2 \to -(2x+6)^2$ . This causes a reflection about the x axis.
$-(2x+6)^2 \to -(2x+6)^2+3$ . This causes a vertical translation, 3 units up

So, if you start from the graph of $y=x^2$ , you have to compress and translate it horizontally, flip it with respect to the x axis, and finally move it up 3 units.

Graph each piecewise function. Then Identify the properties.

Mazyrski [523]

Answer:

The domain is:

x: (-∞, 0] U (0, ∞)

The range is

y: [0, ∞)

Step-by-step explanation:

These types of functions are known as piecewise functions. It has two pieces of functions, you must graph both pieces for each interval.

First, graph:

y = -x for x from -∞ to x = 0

Note that y = -x is the equation of a negative slope line = -1 that passes through the origin

Second, graph:

y = x for x from x = 0 to ∞

Note that y = x is the equation of a positive slope line = 1 that passes through the origin.

The graph of this function is shown in the attached image. Note that it matches the absolute value graph of x.

y = | x |

In this function y it is always positive, and x can be any real number.

Therefore the domain is:

x: (-∞, 0] U (0,∞)

The range is:

y: [0, ∞)
