Subtract (2x - 2y) from the sum of (10x - 2y) and (-3y) is 8x -3y.

Subtraction is a mathematic operation. Which is used to remove terms or objects in an expression.

The sum of  (10x - 2y) and (-3y).

(10x - 2y) + (-3y),

= 10x -2y -3y

= 10x -5y

Subtract (2x - 2y) from the sum of (10x - 2y) and (-3y),

= 10x -5y - (2x - 2y)

= 8x -3y

Therefore, the expression is 8x -3y.

Answer:

D: 1/2 - √3.

Step-by-step explanation:

The Unit Circle is a circle with radius 1 that is used to determine the value of sine and cosine of any angle.

But that table do not directly give the exact value so to solve for its exact value, express π/12 as a sum or difference of two angles where the values of the six trigonometric functions are known.

tan π/12 = tangent (π/4 - π/6)

Using the the difference of angles identity we get,

tan (π/4 - π/6) = (1 - √3 / 3) / (1 + 1 x √3 / 3)

Multiply by 3,

tan (π/4 - π/6) = (3 - √3) / (3 + √3)

Multiply by 3 - √3

tangent (π/4 - π/6) = (3 - √3)(3 - √3) / (3 - √3)(3 + √3)

FOIL and simplify.

tangent (π/4 - π/6) = 9 - 6√3 + 3 / 9 -3

tangent (π/4 - π/6) = 1/2 - √3

Answer:

15.9%

Step-by-step explanation:

Percent decrease formula =

(Initial value - New value/Initial value) × 100

Initial value = 9200kg

New value = 7739.4kg

Percent decrease = (9200 - 7739.4/9200) × 100

Percent decrease = (1460.6/9200) × 100

Percent decrease = 15.8760869565%

Approximately = 15.9%

The percent of decrease in the amount of strawberries used annually is 15.9%

Answer:

Total cost to conduct survey = $2075

Step-by-step explanation:

Given that:

Number of questions on survey = 15

Number of people = 500

Base fee = $1000

Per question charge = $5

Per person surveyed = $2

Let,

q be the number of questions

p be the number of people

Total cost = Base fee + 5q + 2p

Total cost = 1000 + 5(15) + 2(500)

Total cost = 1000 + 75 + 1000

Total cost = $2075

Hence,

Total cost to conduct survey = $2075

Step-by-step explanation:

so you know the how to find the area for a saquare A=a*b first we have to find the area for a circle 10*10=100 A=100cm (2) is the area for our circle

so we have half of the circle so formula for that is A=(πr(2))/2 we know the radius is 5 A=3.14*25/2

A=78.5/2 reason why we are dividing by this number to 2 because we have half of the circle A=39.25 then add two areas together A=100+39.25=....

Answer:

h=(3v)/(pi r^2)

Step-by-step explanation:

you simply have to move everything to one side.

Answer:

h = [tex]\frac{3V}{\pi r^2}[/tex]

Step-by-step explanation:

Given

V = [tex]\frac{1}{3}[/tex]πr²h ( multiply both sides by 3 to clear the fraction )

3V = πr²h ( isolate h by dividing both sides by πr² )

[tex]\frac{3V}{\pi r^2}[/tex] = h

Answer:

A. 15.8

Step-by-step explanation:

First the perimeter of a rectangle = 2 (L +W)

So; 46.4 = 2(L + 7.4)

46.4 = 2L + 14.8

2L = 46.4 - 14.8

2L = 31.6

L =15.8

Answer:

x = 13.5

Step-by-step explanation:

To find x, we use the sine rule

For the sine rule,

the ratio of the sides to the sine of the angle facing the side is equal for all the sides of the triangle

Thus,

x/sin 34 = 11/ sin 27

x = 11 sin 34/sin 27

x = 13.5

Answer:

y = 6(x + 8)² + 4

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Using the method of completing the square.

y = 6x² + 96x + 388

The coefficient of the x² term must be 1, so

factor out 6 from 6x² + 96x

y = 6(x² + 16x ) + 388

To complete the square

add/subtract (half the coefficient of the x- term)² to x² + 16x

y = 6(x² + 2(8)x + 64 - 64) + 388

  = 6(x + 8)² - 384 + 388

y = 6(x + 8)² + 4 ← in vertex form

Answer:

Step-by-step explanation:

From the picture attached,

a). Triangle in the figure is ΔBCF

b). Since, [tex]L_1[/tex] and [tex]L_2[/tex] are the parallel lines and m is a transversal line,

   m∠FBC = m∠BFG [Alternate interior angles]

   Since,  [tex]L_1[/tex] and [tex]L_2[/tex] are the parallel lines and n is a transversal line,

   m∠BCF = m∠CFE [Alternate interior angles]

   By triangle sum theorem in ΔBCF

   m∠FBC + m∠BCF + m∠BFC = 180°

   From the properties given above,

   m∠BFG + m∠CFE + m∠BFC = 180°

   m∠GFE = 180°

Therefore, angle GFE is the straight angle that will be useful in proving that the sum of the measures of the interior angles of the triangle is 180°.

Answer:

y-y1=m (x- x1)…………..(1)

Here m=1/2 and (x1,y1)= (4,-2)

(1) => y-4=1/2(x+2)

=> 2y-8=x+2

=> x-2y-10=0

So, equation of line is x-2y-10=0.
