(-9,3) and (-1,1) find the slope between each pair of points

Answer:

x = -3

y = 8

Step-by-step explanation:

x + 2y = 13    ------------(I)

    x  = 13 - 2y -----------(II)

-2x - 3y = -18 ----------(III)

Substitute x = 13 - 2y in equation (III)

   -2*(13 - 2y)  - 3y = -18

-2*13 - 2y *(-2) -3y = -18

  -26  + 4y  - 3y    = -18             {Combine like terms}

               -26 + y =  -18     {Add 26 to both sides}

                         y = -18 + 26

                         y = 8

Substitute y = 8 in equation (II)

x = 13 - 2*8

  = 13 - 16

x = -3

x = -3

y = 8

Given:

Consider the equation

[tex]2+\dfrac{2x}{5}=-10[/tex]

To find:

The steps and solution for the given equation.

Solution:

We have,

[tex]2+\dfrac{2x}{5}=-10[/tex]

Step 1: Using subtraction property of equality, subtract 2 from both sides.

[tex]2+\dfrac{2x}{5}-2=-10-2[/tex]

[tex]\dfrac{2x}{5}=-12[/tex]

Step 2: Using multiplication property of equality, multiply both sides by 5.

[tex]\dfrac{2x}{5}\times 5=-12\times 5[/tex]

[tex]2x=-60[/tex]

Step 3: Using division property of equality, divide both sides by 2.

[tex]\dfrac{2x}{2}=\dfrac{-60}{2}[/tex]

[tex]x=-30[/tex]

Therefore, the solution of the given equation is [tex]x=-30[/tex].

Answer:

900g

Step-by-step explanation:

This is a case of direct variation as the weight will increase with the number of toys.

hence, 4/600 = 6/x

4x = 3600 (cross multiplication)

x = 900

Hence the weight of 6 such toys is 900g.

Answer:

95 in.²

Step-by-step explanation:

Total surface area of the rectangular pyramid = 4(area of triangle) + area of rectangle

Area of triangle = ½*base*height

base = 5 in.

height = 7 in.

Area of triangle = ½*5*7 = 17.5 in.²

Area of rectangle = Length*width = 5*5 = 25 in.²

Plug in the values

Total surface area of the rectangular pyramid = 4(17.5) + 25

= 95 in.²

Answer:

375

Step-by-step explanation:

m= d * v

d= 3

v= 5 * 5 * 5= 125

125 * 3 = 375

Answer:

7m-7m=8n+8n

m=16n

Step-by-step explanation: U must first link the like terms so in order to do so u must bring over the 7m, now before u brought over the 7m it was a positive 7m now that your bring it over it turns negeitive and the same goes for the term 8n when u carry that term over it turns positive now dont let the subtraction sign foul u it still negative as long as its beside the term it is going to be negative guys dont  forget that, now on to the next step after u cross over and change signs u start to work out now that the like terms are equal u dont  need to worry about them because its given u the go ahead to workout so your main focus is on the subtracting the 7's which  is 0 and leaves u with m u dont  have to put them but i dont recommend it the u start on the next side u and the 8's which is 16 and u put bk the n u have to put bk the terms its important and thats  how u get m=16n.

Answer:

The ratio of juices to ginger ale is 2 to 2

The ratio of orange juice to the cranberry juice is 1 to 1

Step-by-step explanation:

Ginger ale = 2 liters

Orange juice = 1 liter

Cranberry juice = 1 liter

Total ratio = 2 + 1 + 1 = 4

The ratio of ginger ale to the entire punch bowl is 1 to 4.

Ginger ale : entire punch bowl

= 2 : 4

= 1 : 2

Not true

The ratio of orange juice to ginger ale is 2 to 1.

Orange juice : ginger ale = 1 : 2

Not true

The ratio of juices to ginger ale is 2 to 2.

juices : ginger ale = orange juice + cranberry juice : ginger ale

= 1 + 1 : 2

= 2 : 2

True

The ratio of the entire punch bowl to the juices is 2 to 4.

Entire punch bowl : juices 4 : 2

Not true

The ratio of orange juice to the cranberry juice is 1 to 1.

Orange juice : cranberry juice = 1 : 1

True

Answer:

8

Step-by-step explanation:

Let x = the unknown no.

Then

[tex]\frac{50}{20} = \frac{20}{x}[/tex]

50x = 400

 x = 8

If the geometric mean of two numbers is 20, one number is 50 then the other number is 8

"The geometric mean is the average rate of return of a set of values calculated using the products of the terms."

Formula to calculate geometric mean is

[tex]GM = \sqrt{x_{1}.x_{2} }[/tex]

Here,

GM = 20

[tex]x_{1}=50\\ x_{2} =?[/tex]

Substitute the values in the formula

[tex]20=\sqrt{50.x_{2} }[/tex]

Squaring on both sides

[tex]400=50(x_{2})\\ x_{2} =\frac{400}{50} \\x_{2}=8[/tex]

Hence, the other number is 8.
