Answer:

B) -1-6 x +15 = x - 15 +15

Step-by-step explanation:

Explanation:-

Given equation is  –1 – 6 x = x – 15

By addition property of equality

                       ⇒     - 1 - 6 x + 15 = x - 15 +15

                      ⇒      - 6 x + 14  = x

subtracting 'x' on both sides ,we get

                       ⇒      - 6 x -x +14 =0

                        ⇒      - 7 x +14 =0

                         ⇒      -7 x = - 14

   Dividing '-7'  on both sides , we get

                                 x  = 2

The solution of given equation is    x  = 2

y = 2x + 7

Answer:

Option (2), (3) and (4)

Step-by-step explanation:

Let the equation of the line representing the given table is,

y - y' = m(x - x')

where 'm' = slope of the line

(x', y') is the point lying on the line.

Let the two points (-6, -10) and (-4, -9) lie on the line

Slope 'm' = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

               = [tex]\frac{-9+10}{-4+6}[/tex]

               = [tex]\frac{1}{2}[/tex]

Equation of the line passing through (-4, -9) with slope [tex]\frac{1}{2}[/tex] will be

y - (-9) = [tex]\frac{1}{2}(x+4)[/tex]

y + 9 = [tex]\frac{1}{2}(x+4)[/tex]

Equation of the line passing through (-6, -10) with slope = [tex]\frac{1}{2}[/tex]

y - (-10) = [tex]\frac{1}{2}(x+6)[/tex]

y + 10 = [tex]\frac{1}{2}(x+6)[/tex]

Equation of the line passing through (6, -4) and slope =  [tex]\frac{1}{2}[/tex]

y + 4 = [tex]\frac{1}{2}(x-6)[/tex]

Therefore, Options (2), (3) and (4) will be the answer.

Answer: Option no. C 486/11

The requried slope of the hill which is 11 yd tall and 486 yd long is 11/486. Option D is correct.

To find the slope of a hill, we can use the formula: slope = rise/run.

In this case, the rise refers to the vertical change, which is the height of the hill, given as 11 yd. The run refers to the horizontal change, which is the length of the hill, given as 486 yd.

Using the formula, we can calculate the slope:

slope = rise/run

slope = 11 yd / 486 yd

To simplify the slope, we can divide both the numerator and the denominator by the greatest common divisor, which is 1 in this case:

slope = 11 / 486

Therefore, the slope of the hill is 11/486.

Answer:

102

Step-by-step explanation:

You can split that shape up into 2 rectangles to make it easier get the area of each rectangle and add them together.

Step 1

Identify the width and height

Step 2

Multiply the sides to get the answer

For example if we split the shape we will have 9,10 and 2,6

9 times 10 is 90

and 2 times 6 is 12

Add the 2 and get 102

Step-by-step explanation:

29 = 7y -4 +y+6

29 = 8y+2

8y = 27

y = 27/8

y =. 3.375

The midpoint of a line is the middle of the distance between two points. The value of y if  is the midpoint of AC is 3.375

The midpoint of a line is the middle of the distance between two points. Given the following parameters

MN = 7y - 4, and;

NP= y + 6

MP = 29

If N is between M and P.  hence;

MN + NP = MP

Substitute

7y-4 + y + 6 = 29

8y + 2 = 29
8y = 27

y = 27/8

y = 3.375

Hence the value of y if   N is between M and P is 3.375

Answer:

x = 10

BD = 74

Step-by-step explanation:

Find x by setting 3x+7 equal to 37. Solve for x by subtracting 7 on both sides then divide by 3 to get x=10.

Since 37 is half of AC, multiply that by 2 to find AC or BD, which are the exact same length of 74.

Answer:

x=10 and BD=74

Step-by-step explanation:

In a rectangle, the two parts of the diagonals are always equal to each other. This means that AE=CE=BE=ED.

So, if AE is 3x+7, this means DE and BE are also 3x+7, so BD is twice that, or 2(3x+7) which when you multiply it is 6x+14.

Oh, also, since it says CE=37, this means that 3x+7=37

3x+7=37

    -7   -7

3x=30

x=10

Now that you know that BD is 6x+14, and x is 10, simply multiply it.

6(10)+14=BD

60+14=BD

74=BD
