using the slope formula find the slope of the line that passes through these points (-2,4) and (4,-1)

Answer:

            y  =  [tex]\frac{1}{2}[/tex] x - 5

Step-by-step explanation:

 Given expression:

        2x + y  = -5

Find the equation of the line perpendicular

Solution:

A line perpendicular to this line will have a negative inverse slope;

  Equation of any line is given as;

           y  = mx + c

y and x are the coordinates

 m is the slope

  c is the intercept

 Re-write;

         2x + y  = -5

                y  = -2x - 5

Now,

          we know that the slope is -2

A line perpendicular will have a slope of [tex]\frac{1}{2}[/tex] ;

  So;

   Equation of the line is;

            y  =  [tex]\frac{1}{2}[/tex] x - 5

Answer:

480 ft^3

Step-by-step explanation:

The formula is lwh/3 so plug in length, width, and height.

Answer:

The length is 5 meters and the width is 3 meters.

Step-by-step explanation:

The dimensions of the rectangle are 5 meters by 3 meters.

Let's say the length of the rectangle is l and the width is w. We are given that w = l - 2 and lw = 15.

We can substitute the first equation into the second equation to get:

l(l - 2) = 15

This simplifies to:

[tex]l^2[/tex] - 2l - 15 = 0

We can factor this equation to get:

(l + 3)(l - 5) = 0

This means that either l = -3 or l = 5.

Since the length of a rectangle cannot be negative, we know that l = 5.

Substituting this value back into the equation w = l - 2, we get:

w = 5 - 2 = 3

Therefore, the dimensions of the rectangle are 5 meters by 3 meters.

[tex]a : 4^2\\\\b: 4ft[/tex]

Step-by-step explanation:

[tex]\sqrt{16} = 4\\a : 4^2\\\\b: 4ft[/tex]

The area of the solar panel written as a power is 4 square feet.

The side lengths of the solar panel are 4 feet.

Area of square is the square of its side.

It is given that a square solar panel has an area of 16 square feet.

By simply using this formula;

[tex]\sqrt{x} = x^\frac{1}{2}[/tex]

Taking root square we get;

[tex]\sqrt{16} = 4[/tex]

Thus, power = [tex]4^{2} ft[/tex]

Answer:

  10

Step-by-step explanation:

1 child likes all three

4 like apples and bananas, so 4-1 = 3 like apples and bananas only

3 like apples and peaches, so 3-1 = 2 like apples and peaches only

2 like peaches and bananas, so 2-1 = 1 like peaches and bananas only

7 like apples, but 3+2+1 like one or more other fruits, so 1 likes apples only

6 like bananas, but 3+1+1 like one or more other fruits, so 1 likes bananas only

5 like peaches, but 2+1+1 like one or more other fruits, so 1 likes peaches only

__

1 + 1 + 1 = 3 like exactly 1 fruit;

3 + 2 + 1 = 6 like exactly 2 fruits;

1 likes exactly 3 fruits.

The total number of children is 3 + 6 + 1 = 10.

Assuming all the referenced children are in the family, there are 10 children in the family.

Answer:

110 walnuts

Step-by-step explanation:

There are 330 walnuts in 6 bags.

Each bag has the same number of walnuts

Hence, the number did walnuts in one bag=

6 bags = 330 walnuts

1 bag = x walnuts

Cross Multiply

6 × x = 1 × 330 walnuts

x = 330 walnuts/6

x = 55 walnuts

Each bag contains 55 walnuts

The number of walnuts that are in 2 bags is calculated as:

1 bag = 55 walnuts

2 bags =

2 × 55 walnuts

= 110 walnuts

There are 110 walnuts in 2 bags.

16.94>10

Step-by-step explanation:

We are given: 2a+b =7 and 3a-2b=3 , We need to find how much is 7a greater than 10.

First we need to solve equations to find value of a

[tex]2a+b =7---eq(1)\\ 3a-2b=3---eq(2)[/tex]

Multiply eq(1) by 2 and add both equations

[tex]4a+2b =14\\ 3a-2b=3\\------\\7a=17\\a=\frac{17}{7}\\a=2.42[/tex]

Putting value of a in eq(1) to find b

[tex]2a+b=7\\2(2.42)+b=7\\4.84+b=7\\b=7-4.84\\b=2.16[/tex]

Now, a = 2.42 and b=2.16

Finding by how much is 7a  greater than 10

[tex]7a>10[/tex]

Putting a = 2.42

[tex]7a>10\\7(2.42)>10\\16.94>10[/tex]
