A line segment has the endpoints P(10,9) and Q(2,5).Find the coordinates of its midpoint M.

Answer:

y = - 3x + 21

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x + 4 ← is in slope- intercept form

with slope m = - 3

Parallel lines have equal slopes , then

y = - 3x + c ← is the partial equation

To find c substitute (7, 0 ) into the partial equation

0 = - 21 + c ⇒ c = 0 + 21 = 21

y = - 3x + 21 ← equation of parallel line

Answer: slope = 4/3

Step-by-step explanation:

(24-12)/(6- -3)

= 12/9

= 4/3

Answer:

93 degrees

Step-by-step explanation:

First, you would need to observe the image and see where to start off. You can see that there is a triangle below the "?" and you would be able to get the answer if you can find the measures of the small triangle(because of vertical angles) So,

180-127= 53.

180-146=34.

Since the angles of a triangle adds up to 180 degrees, 53+34+x=180.

x=93

Now, just flip the angle around and "?" = 93 degrees.

Answer:  93 degrees

===========================================================

Explanation:

Let x be the question mark angle we want to find.

Let y be adjacent to the 127 degree angle

Let z be adjacent to the 146 degree angle.

Refer to the diagram below.

Note that in the diagram, I have a second copy of 'x' because the two x angles are vertical angles. Vertical angles are always congruent.

Let's find angle y

127+y = 180

y = 180-127

y = 53

Do the same for angle z

z+146 = 180

z = 180-146

z = 34

Then notice how,

x+y+z = 180

x+53+34

x+87 = 180

x = 180-87

x = 93

Answer:

x = 8

ABD = 46 degrees

DBC = 44 degrees

Step-by-step explanation:

Complementary Angles: two angles who’s sum together is 90 degrees

2x + 30 + 3x + 20 = 90

5x + 50 = 90

5x (+ 50 - 50) = 90 - 50

5x = 40

5x/5 = 40/5

x = 8

2(8) + 30

16 + 30

46

3(8) + 20

24 + 20

44

ABD = 46

DBC = 44

This is what I did in the photo

[tex]\\ \sf\longmapsto x+40=90[/tex](Complementary)

[tex]\\ \sf\longmapsto x=90-40[/tex]

[tex]\\ \sf\longmapsto x=50[/tex]

Now

[tex]\\ \sf\longmapsto y+40=180[/tex]

[tex]\\ \sf\longmapsto y=180-40[/tex]

[tex]\\ \sf\longmapsto y=140[/tex]

Now

[tex]\\ \sf\longmapsto x+y=140+50=190[/tex]

Get a graph for this one, the number is the first parameter is x, find that x value along the x axis then after finishing it locate v, find y value along the y axis.

Solve:

1. x = 3

2. x = 1

3. x = 3

4. x = x = 5

5. x = 8

6. x = 12

7. x = 9

12. x = -12

13. x = 5

14. x = 6

15. x = 16

Step-by-step explanation:

Variables - in algebra is a symbol or a letter.

Constants - are numbers

Coefficients - are the numbers that are with variables

Use this description and circle the examples.

For the plot use a gird, or gets a coordinate plane.

Lastely for the Solve example minus or plus the constant with the coefficient and variable forum the constant outside that has been equal to. Then divide by the variable coefficient, and you will get your x value. Example:

34 - 13 = 21 / 7 thus x = 3

Answer:

Unicorn A is 300 years old

Unicorn B is 20 years old

Explanation:

15x + x = 320

16x = 320

x = 20

15 * 20 + 20 = 320

We have that Each unicorn is 20 ans 300 years receptively

[tex]A=300\\\\B=20[/tex]

From the Question we are told that

UNICORN A IS 15 TIMES OLDER THAN  UNICORN B.

THE SUM OF THEIR AGES  IS 320 YEARS.

Let

x=age of unicorn A

y=age of unicorn B

Therefore

[tex]x=15y....1\\\\\x+y=320.....2[/tex]

Sub (1) into 2

[tex](15y)+y=320\\\\y=20[/tex]

therefore

[tex]x=15(20)\\\\x=300[/tex]

In conclusion

Each unicorn is 20 ans 300 years receptively

[tex]A=300\\\\B=20[/tex]

let the first triangle to have perimeter, P

let the second triangle to have perimeter, P'

Answer: 1 hour and 8 minutes or 68 minutes.

Step-by-step explanation:

For this question I would start by finding how many minutes it would take to get to 4pm since it's the closest hour to 3:52 pm.

If we think of the 00 in 4:00 as 60, then we can do 60-52=8.

Then we know that 4:00 + 1 hour is 5:00.

To find the final answer add 8 minutes + 1 hour, which is 1 hour and 8 minutes.

This can also be answered as 68 minutes because, 60 minutes (1 hour) +8 minutes = 68 minutes.
