Answer:

x = 12 or x = -6

Step-by-step explanation:

Solve for x over the integers:

abs(x - 3) = 9

Split the equation into two possible cases:

x - 3 = 9 or x - 3 = -9

Add 3 to both sides:

x = 12 or x - 3 = -9

Add 3 to both sides:

Answer: x = 12 or x = -6

Answer:

length is 20 meters

width is 12 meters

Step-by-step explanation:

x = length

y = width

x = 2y - 4

x×y = 240

using the first equation as substitute in the second equation we get

(2y - 4)×y = 240

2y² - 4y - 240 = 0

the solution to such a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

here we are going for y instead of x, but it is the same principle.

a = 2

b = -4

c = -240

y = (4 ± sqrt(16 - 4×2×-240))/4 = (4 ± sqrt(16 + 1920))/4 =

= (4 ± sqrt(1936))/4 = (4 ± 44)/4 = (1 ± 11)

y1 = 1 + 11 = 12

y2 = 1 - 11 = -10

negative side lengths don't make any sense, so, y = 12 meters remains.

x = 2y - 4 = 2×12 - 4 = 24 - 4 = 20 meters

Answer: Part A: a square pyramid Part B: 84 square feet

Step-by-step explanation:

Part A: The shape will have a base that is a square with triangles on each of its edges that connect at a point at the top.

Part B: The amount of nylon needed is the surface area of the net. There is a square and two triangles. The square has a side length of 6 so its area will be 6*6=36 square feet. Each triangle has a base of 6 and a height of 4 so each of their areas will be [tex]\frac{6*4}{2}=12[/tex] square feet. Adding up the area of the 4 triangles and the square gives us 4*12+36=84 square feet.

The equation [tex]kw^{2} -mw=s[/tex] solved for [tex]w[/tex].

[tex]w=[/tex] [tex]$\frac{m\pm\sqrt{m^{2}+4 k s}}{2 k}$[/tex]

Step-by-step explanation:

Given:

[tex]kw^{2} -mw=s[/tex]

To solve the given equation for [tex]w[/tex].

[tex]kw^{2} -mw=s[/tex]

[tex]kw^2-mw-s=0[/tex]

Using Quadratic formula,

[tex]$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$[/tex]

Comparing the equation  [tex]kw^{2} -mw-s=0[/tex] with the formula,

[tex]x=w[/tex]

[tex]b=m[/tex]

[tex]a=k[/tex]

[tex]c=s[/tex]

Step-by-step explanation:

a) 64 (A=bh)

b) 96 ((16x12)÷2)

Answer:

Step-by-step explanation:

a) base = AB = 16 cm

height = DX = 6cm

Area of  the parallelogram = base * corresponding height to the base

                                            = 16 * 6

                                            = 96 sq. cm

Area of parallelogram =  96 sq .cm

BC * DY = 96

12 * DY = 96

      DY = 96/12

      DY = 8 cm

Answer:

Step-by-step explanation:

|-3| = 3 and |3| = 3 to

Answer:

2 integers at a time will be able to have the same absolute value. This is because integer can be both positive and negative, while absolute value always remains positive:

The absolute value of both 2 and (-2) is 2.

Answer:

see explanation

Step-by-step explanation:

Substitute the given values of x into f : x → [tex]\frac{3}{7}[/tex] x + 4

x = - 14 → ([tex]\frac{3}{7}[/tex] × - 14) + 4 = (3 × - 2) + 4 = - 6 + 4 = - 2

x = 28 → ( [tex]\frac{3}{7}[/tex] × 28) + 4 = (3 × 4) + 4 = 12 + 4 = 16

x = [tex]\frac{7}{8}[/tex] → ([tex]\frac{3}{7}[/tex] × [tex]\frac{7}{8}[/tex] ) + 4 = [tex]\frac{3}{8}[/tex] + 4 = [tex]\frac{3}{8}[/tex] + [tex]\frac{32}{8}[/tex] = [tex]\frac{35}{8}[/tex]

x = - [tex]\frac{2}{9}[/tex] → ([tex]\frac{3}{7}[/tex] × - [tex]\frac{2}{9}[/tex] ) + 4 = ([tex]\frac{1}{7}[/tex] × - [tex]\frac{2}{3}[/tex]) + 4 = - [tex]\frac{2}{21}[/tex] + [tex]\frac{84}{21}[/tex] = [tex]\frac{82}{21}[/tex]

Answer:

See below in bold.

Step-by-step explanation:

1. 3/7 * -14 + 4

   = -6 + 4

    = -2.

2. 3/7 * 28 + 4

   = 12 + 4

    = 16.

3 3/7 * 7/8 + 4

   =  3/8 + 4

    =   35/8 or 4 3/8.

4. 3/7 * -2/9 + 4

   = -6/63 + 4

   = -2/21 + 4

    = -82/21 or -3 19/21.

Answer:

y= 37.5

Step-by-step explanation:

x = 30°

180-30= 150

4x=150

x = 37.5

Answer:

Y = 40

Step-by-step explanation:

I do not understand that language but if it is asking what Y is equal to when x is equal to 30 degrees and EFG is a straight line.

1. 3Y + 2X = 180 (Straight angle)

2. X = 30 (given)

3. therefore 2X = 2x30

                          = 60

4. Therefore 3Y + 60 = 180

5. 3Y = 180 - 60

6. 3Y = 120

7. Y = 120/3

8. Y = 40

Answer:

The average rte of change = 6

2) The average rate of change over an interval is the ratio of the total change in the determinate variable or function (values of the output of the function) to the change in the indeterminate variable (values of the input of the function)

Step-by-step explanation:

1) The average of change of the function is found as follows;

At x = 0.75, y = -0.5, at x = 1.125, y = 1.75

Therefore, the average rate of change = (1.75 - (-0.5))/(1.125 - 0.75) = 6

2) The average rate of change over an interval on a graph or of a curve is found by dividing the difference between the y-coordinate values of the two points on the graph by the difference of the x-coordinate values of the two points.
