Answer:

-1/5

Slope is given by the change in y over the change in x.

Change in y: 2-1= 1

Change in x: 5-10= -5

Answer:

-5

Step-by-step explanation:

In order to find the slope of two points you need to remember a few things.

(x,_)

The first number in an ordered pair is the x value. That determines the position of a point on the x axis. (Left or right)

(_,y)

The second number in an ordered pair is the y value. That determines the position of a point on the y axis. (Up or down)

(x,y)

Calculating slope

<em>Take the y value from one of your ordered pairs and subtract that value from the other y value. </em>

(10,1) and (5,2)

<em>We will take the numbers 1 and 2.</em>

1-2=-1

<em>Take the x value from the y value you subtracted. Since we used 1 as our first y value we will take its x value 10</em>

(If we started with 2 we would take its x counterpart, which is 5)

10-5=5

<em>Divide -1 by 5 and you get -1/5</em>

(y2-y1) divided by (x2 - x1)

:) Hope this helped

Answer:

Step-by-step explanation:

<u><em>Q 4.</em></u> (25m + 25m) ÷ 25 sec. = <em>2 m/sec.</em>

<u><em>Q 5.</em></u> This question belongs to Physics and not Mathematics!!!

Wavelength (lambda) = Velocity (v) ÷ Frequency ( sec^{-1} or Hz )

f = v / (lambda)

f = 3 / 2 = <em>1.5 (Hz)</em>

<u><em>Q 6.</em></u> 0.060 ÷ 2 = <em>0.030 m</em>

Suppose f(x)=x^2. what is the graph of g(x)=f(3x)?<br>​
Katarina [22]

Answer:

D

Step-by-step explanation:

because since there is no negative sign in front of the 3x we automatially know there is no reflection so that rules out answers A and B. Then, since 3 is greater than 1 we can determine that it is a stretch which would rule out answer C so the answer is D

Can you explain how you would convert 4 m to millimeters?
Andrew [12]
M to millimetres is 3 steps. m > dm > cm > mm. since it is 3 steps down, the comma goes 3 places left. 4 > 0,4 > 0,04 > 0,004. so 4 m is equal to 0,004 mm

The cost of 4 cookies, 6 doughnuts, and 3 boxes of doughnut holes is $8.15. The cost of 2 cookies, 3 doughnuts, and 4 boxes of d
Naddika [18.5K]

Answer:

$1.25

Step-by-step explanation:

This can best be determined using a set of linear equations that are solved simultaneously.

This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations.

Let the cost of a cookie be c, cost of a doughnut be d and that of a box of doughnut hole be h then if cost of 4 cookies, 6 doughnuts, and 3 boxes of doughnut holes is $8.15, we have

4a + 6d + 3h = 8.15

and the cost of 2 cookies, 3 doughnuts, and 4 boxes of doughnuts holes is $7.20 then

2a + 3d + 4h = 7.20

Dividing the first by 2

2a + 3d + 1.5h = 4.075

subtracting from the second equation

2.5h = 3.125

h = 1.25

The cost of a box of doughnut holes is $1.25

Find the approximate perimeter of the trapezoid? PLSSS HELPPP
choli [55]

Answer:

49

Step-by-step explanation:

side 1 = |18-3|= 15

side 2 = |12-3| = 9

side 3 = |16-4| = 12

side 4: \sqrt{(18-12)^2 + (4-16)^2} \\ \sqrt{36+144} \\ = \sqrt{180} \\ = 13,4

perimeter = 15 + 9 + 12 + 13,4= 49,4 = 49
