Answer:

We conclude that:

m∠XWY = 41°

Step-by-step explanation:

Given

m∠VWX = 139°

m∠YWZ = 23°

To determine

m∠XWY = ?

We know the measure of the angle of a straight is 180°.

As m∠VWX and m∠XWY lie on a straight line.

Thus, the sum of m∠VWX and m∠XWY must be 180°

so we get the equation

m∠VWX + m∠XWY =  180°

Given that m∠VWX = 139°

so substituting m∠VWX = 139° in the equation m∠VWX + m∠XWY =  180°

139° + m∠XWY = 180°

m∠XWY = 180° - 139°

m∠XWY = 41°

Therefore, we conclude that:

m∠XWY = 41°

3y=5x-15

Divide each side by 3

y=5/3x-5

y=mx+b

b is the y-intercept

Answer:

Slope: [tex]m=-\frac{1}{2}[/tex]

y-intercept: [tex](0,-1)[/tex]

Equation: [tex]y=-\frac{1}{2}x-1[/tex]

Step-by-step explanation:

Slope-intercept form of an equation is written as [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.

The slope of a line that passes through the points [tex](x_1,\: y_1)[/tex] and [tex](x_2, \: y_2)[/tex] is [tex]m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}[/tex]. Using the coordinates [tex](-2, 0)[/tex] and [tex](2,-2)[/tex] as given in the problem, we have slope of this line to be:

[tex]m=\frac{-2-0}{2-(-2)}=\frac{-2}{4}=-\frac{1}{2}[/tex].

Now using this slope we've found and any point the line passes through, we can find the y-intercept of this equation:

[tex]0=-\frac{1}{2}(-2)+b, \\ b=-1[/tex]

Therefore, the equation of this line in slope-intercept form is [tex]\fbox{$y=-\frac{1}{2}x-1$}[/tex].

The y-intercept occurs when [tex]x=0[/tex]:

[tex]y=-\frac{1}{2}(0)-1, \\\\y=1[/tex]

Thus, the y-intercept is

[tex](0, -1)[/tex]

The length of a rectangle is 1 7/9 in and its width is 3/4 of its length. Find the area of this rectangle.

Answers

Answer:

The answer is 4/3 or 1.33 square units.

Step-by-step explanation:

Length = 1 + 7/9 = 16/9 units.

Width = 3/4 units.

Since area of rectangle = Length * Width

Area = 16/9 * 3/4 = 4/3 square units.

Step-by-step explanation:

The perimeter of the rectangle is (20x + 6)inches

The perimeter of a rectangle

The formula for calculating the perimeter of a rectangle is expressed as:

P = 2l + 2w

Given that;

l = 8x - 1

w = 2x + 4

Susbtitute

P = 2(8x - 1) + 2(2x + 4)

Expand

P = 2(8x) - 2(1) + 2(2x) + 2(4)

P = 16x - 2 + 4x + 8

P = 16x + 4x - 2 + 8

A. AAS(Angle-Angle-Side)

Step-by-step explanation:

From the image, you can already see 1 angle and 1 side measured.

But, angle KLJ and angle MLN are congruent to each other as well because they are vertical angles (angles on opposite sides). And vertical angles are always congruent to each other.

So in total, we have 2 angles and 1 side congruent to each other,

<KLJ and <MLN

<LKJ and <LMN

KJ and MN

From the other (based on the image), they are ordered in a angle angle, side format. So the answer is AAS.

Graph the image of the figure after a dilation with a scale factor of 3 centered at (2, −7).

Use the Polygon tool to graph the quadrilateral by connecting all its vertices.

Answers

Answer:

Step-by-step explanation:

Each point moves 3 times the distance from the center of dilation that it was.

You can compute the new coordinates by ...

 L = P - O . . . . . the length from O to P is P-O for some point P and origin O

Then 3 times that distance is

 3L = 3P -3O

We want to find the point P' that is 3L from O, so we add this distance to the coordinates of O. We get ...

 P' = 3L +O = 3P -3O +O

 P' = 3P -2O

So, for the lower left point A(-2, -7), the dilated image point A' is ...

 A' = 3(-2, -7) -2(2, -7) = (-6, -21) +(-4, 14) = (-10, -7)

That is, ...

 A' = 3A +(-4, 14)

The coordinates of the remaining points can be found similarly.

___

On a graph, it is usually fairly easy to count the grid squares in each direction between the point of interest and the center of dilation. The image point is 3 times the distance in each direction (horizontally, vertically).
