Answer:

Equation of the line in point-slope form: y - 5 = -⅚(x - 2)

Equation of the line in slope-intercept form: y = -⅚x + 20/3

Step-by-step explanation:

Equation of a line can be expressed in the point-slope form as y - b = m(x - a), where,

m = slope = -⅚

a = 2

b = 5

Substitute the values into y - b = m(x - a):

y - 5 = -⅚(x - 2) => point-slope form.

We can rewrite this in the slope-intercept form, such as:

Multiply both sides by 6

6(y - 5) = -5(x - 2)

6y - 30 = -5x + 10

6y - 30 + 30 = -5x + 10 + 30

6y = -5x + 40

Divide both sides by 6

y = -5x/6 + 40/6

y = -⅚x + 20/3

The measure of two consecutive angles of a parallelogram are in the ration of 7:5. What is the measure of the obtuse angle of the parallelogram.​

Answers

Consecutive angles in a parallelogram are supplementary angles which when added together equal 180 degrees.

The ratio is 7:5 so we would have:

7x + 5x = 180

Simplify:

12x = 180

Divide both sides by 12:

X = 15

So one angle is 7 x 15 = 105 degrees

The other angle is 5 x 15 = 75 degrees

An obtuse angle is an angle greater than 90 degrees.

The obtuse angle would be 105 degrees.

Joey had 26 game cards. His friend Richard gave him some more, and now Joey has 100 cards. How many cards did Richard give to Joey?

Answers

Given:

Joey had 26 game cards.

His friend Richard gave him some more, and now Joey has 100 cards.

To find:

How many cards did Richard give to Joey?

Solution:

Let x be the number of cards that Richard give to Joey.

Joey had 26 game cards.

Now, the total cards joey has [tex]=26+x[/tex]

Joey has total 100 cards.

[tex]26+x=100[/tex]

[tex]x=100-26[/tex]

[tex]x=74[/tex]

Therefore, Richard gave him 74 cards.

Draw the following triangle after a 90° clockwise rotation about the origin.

Answers

Answer:

Its gonna be in the same spot but just on the left

Step-by-step explanation:

The graph is attached with the solution

What is rotation?

Each point in a figure is transformed into a rotation by rotating it a specific amount of degrees around another point.

The coordinates of the vertices of the given triangle are (3,-2), (1,-5), and (5,-4).

The coordinate rule for 90° clockwise rotation about the origin is:

(x,y)→(y,-x)

Therefore, the vertices of the triangle are transformed as follows:

(3,-2) → (-2, -3)

(1,-5) → (-5,-1)

(5,-4) → (-4,-5)

Now, plot the image points (-2,-3), (-5,-1), and (-4,-5) and connect them to draw the required triangle.

The graph is attached with the solution.

Quadrilateral ABCD is inscribed In a circle.
What is the measure of angle A?

Answers

Answer:

[tex] m\angle A = 133\degree [/tex]

Step-by-step explanation:

Quadrilateral ABCD is inscribed In a circle.

So, ABCD is a cyclic Quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

Therefore,

(4x + 5)° + (x + 15)° = 180°

(4x + 5 + x + 15)° = 180°

(5x + 20)° = 180°

5x + 20 = 180

5x = 180 - 20

5x = 160

x = 160/5

x = 32

[tex] m\angle A = (4x + 5)\degree [/tex]

[tex] m\angle A = (4\times 32+ 5)\degree [/tex]

[tex] m\angle A = (128+ 5)\degree [/tex]

[tex] m\angle A = 133\degree [/tex]

▪a=180-148=32

Now,

a+b=90(A right angle is equal to 90)

So,

▪b=90-a=90-32=58

Then,

b=b(base of iscoceles angles of traingle)
