Answers

Answer:

-1/2

Step-by-step explanation:

Formula to find slope is y2-y1/x2-x1

Chose one ordered pair to be the 2 and the other one to be the 1

I chose the 2nd one to be 2.

Plug in the y-value from the 2nd ordered pair to y2 because its the 2.

Plug in the x-value from the 2nd ordered pair to x2 because its the 2.

Now you have 0-y1/5-x1

Do the same thing but for the 1.

Plug in the y-value from the 1st ordered pair to y1 because its the 1.

Plug in the x-value from the 1st ordered pair to x1 because its the 1.

Now you have 0-5/5--5

In this situation, you have 2 minus signs.

2 minus = 1 positive.

Now you have 0-5/5+5

Simplify.

Now you have -5/10.

Simplify.

-1/2.

Hope this helps!

please i need help as soon as possible

Answers

The equation of the line is y= -2x+10

First you need to find the slope of the two points.
The slope is -2

Then you use the slope intercept form to find the y intercept.
y=2x+b

You then have to plug in the x and y points.

6= -2(2) + b
6= -4+b
b=10

Lastly write using the slope intercept

y= -2x+10

(╯︵╰,)​

Answers

Answer:

Activity 1:-

1) Pi (π) is the ratio of circumference and the diameter of the circle which is 22/7. So

[tex]\frac{c}{d} =\pi = \frac{22}{7}[/tex]

[tex]=> c = \frac{22}{7} d[/tex] where circumference is directly proportional to diameter (d).

2) Area of a parallelogram = Altitude × Base

Base = 10 cm. So ,

[tex]A = 10a[/tex] where area (A) is directly proportional to altitude (a).

3) Let the fare of 1 unit distance be f

So, for distance d , total fare (F) will be [tex]F = fd[/tex] where total fare (F) is directly proportional to distance (d).

4) Let the distance be 'D' , speed be 's' & time be 't' .

We know that [tex]s = \frac{D}{t}[/tex] where speed (s) is directly proportional to distance (D) & inversely proportional to time (t).

5) We know that area of a square (A) = side² (s²)

[tex]=> A = s^{2}[/tex] where area(A) is directly proportional to side(s).

Activity 2:-

1) p is directly proportional to sum of u & w.

⇒ p ∝ u + w

⇒ p = k (u + w)

Putting the values of p , u & w

⇒ 14 = k(4 + 3)

⇒ 7k = 14

k = 14/7 = 2

2) r is directly proportional to square of t.

⇒ r ∝ t²

⇒ r = k × t²

Putting the values of r & t

⇒ 16 = k × 16²

k = 16² ÷ 16 = 16

3) y is directly proportional to cube root of x.

⇒ y ∝ ∛x

⇒ y = k × ∛x

Putting the values of x & y ,

⇒ 2 = k × ∛27

⇒ 3k = 2

k = 2/3

4) z is directly proportional to cube of d.

⇒ z ∝ d³

⇒ z = k × d³

Putting the values of d & z ,

⇒ 5 = k × 2³

⇒ 8k = 5

k = 5/8

5) Total Surface Area (SA) is directly proportional to square of the sides (s).

⇒ SA ∝ s²

⇒ SA = k × s²

Putting the values of SA & s ,

⇒ 96 = k × 4²

⇒ 16k = 96

k = 96/16 = 6

39,000 over 12 = ?? Also, show your work so I can do the rest of these myself

Answers

Answer:

3,250

Step-by-step explanation:

Let's go from left to right, using multiple of 12 times a power of 10 in the process.

What is the closest multiple of 12,000 (12 * 10^3) to 39,000 without going over? That's 3 (36,000). That's the thousands digit in this answer.

12,000 * 3 = 36000

39000 - 36000 = 3000

What's the closest multiple of 1,200 (12 * 10^2) to 3,000 without going over? That's 2 (2,400). That's the hundreds digit.

1,200 * 2 = 2,400

3,000 - 2,400 = 600

What is the multiple of 120 (12 * 10) closest to 600 without going over? That's 5 (600, it's even!). That's the tens digit. Since it goes evenly, 0 is the ones digit.

120 * 5 = 600

600 - 600 = 0.

The answer to 39,000 over 12 is 3,250.

a quadrilateral has 2 angles that measure 100 and 60 degrees the other angles have a ratio of 3:17 . what are the measures of those angles?

Answers

Answer:

30° , 170°

Step-by-step explanation:

Let the remaining two angles be 3x & 17x. As it is a quadrilateral , the sum of all the angles of quadrilateral is 360°. So,

[tex]3x + 17x + 60 + 100 = 360[/tex]

[tex] = > 20x = 360 - 160 = 200[/tex]

[tex] = > x = \frac{200}{20} = 10[/tex]
