Answer:

<h2>The slope of the new road is zero.</h2>

Step-by-step explanation:

According to the image attached, D street is represents by a vertical line, which angle of inclination is 90°. In other words, the slope of D street is infinite.

So, if the new road is going to be perpendicular to D street, that means the new road has 0° of inclination, because if they are perpendicular and D street is vertical, that means the new road is horizontal, which have 0° of inclination.

Now, the slope of an horizontal line is zero.

Therefore, the slope of the new road is zero.

Answer:

The slope of the new road is 0.

Step-by-step explanation:

the slope of d street line is tan(90)

[if the angle made by a line with x axis is $\alpha$ then, the slope of that line will be tan( $\alpha$ ) ]

here, the angle made by the d street line with x axis is 90 degrees.

if a road is to be built which is perpendicular to d street , it should make 0 degrees i.e, it should be parallel to x axis .

so, the slope of new road will be tan(0) = 0

if pentagon abcd was reflected over the axis y-axis, reflected over the x-axis, and rotated 180, where would be point A' lie

frez [133]

A reflection over the x axis coupled with another reflection over the y axis leads to a rotation of 180 degrees.

In other words,

Start with point A. Reflect over the x axis to get point B. Reflect B over the y axis to get point C. To go from A to C, we can rotate A 180 degrees about the origin.

----------------

So this means that if we do those reflections and then do the rotation, then we end up back where we started. Wherever point A is located, the point A' will also be located at the same position with the same coordinates.

(-2,17)(-1,13)(1,5)(2,1)(3,-3)<br> The rate of change is ____.

7nadin3 [17]

Answer:

The rate of change in -4

Step-by-step explanation:

The rate of change is also known as the slope

To do this, take two points {(-2, 17) , (-1, 13)} and find the slope

m = slope

m = change in y/change in x

m = 13 - 17/-1 - (-2)

m = -4/1

m = -4

The rate of change in -4

Need help on #6 step by step I'm so confused how this works I always get stuck

inna [77]

To find the variable x, set the two outside equations equal to each other because all sides are equal
x+13=3x+3
13=2x+3
10=2x
x=5

then to find h, you set the equation equal to 90 because that's how many degrees it is
2h-45=90
2h=135
h=67.5

The company, hewerrtt, would like to make letter codes using all of the letters in the word hewerrtt. how many codes can be made

shtirl [24]

<span>If the company, hewerrtt, would like to make letter codes using all of the letters in the word hewerrtt, they would be able to make five codes. Altogether, there are eight letters in the word, but there are duplicates of the letter e, the letter r, and the letter t, so that takes out three possibilities. Three subtracted from eight is equal to five, therefore the company can make five codes using the company name.</span>
