Answer:

The answer for the given expression is 23 after putting the values of a,b and c.

Step-by-step explanation:

Given expression is:

[tex](\frac{2c}{a})^2-10*\frac{(b+a)}{c}[/tex]

We have to find the value of expression, when

a = -2, b = 3 and c = 5

We will put these values in the given expression and then simplify the given expression,

[tex](\frac{2*5}{-2})^2-10*\frac{3+(-2)}{5}\\\\(\frac{10}{-2})^2-10*\frac{3-2}{5}\\\\(-5)^2-10*\frac{1}{5}\\25-2\\23[/tex]

Hence,

The answer for the given expression is 23 after putting the values of a,b and c.

Step-by-step explanation:

AB = AC

BD = BD

AD = AD

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°.

Step-by-step explanation:

Answer:

y=-2x+2 (if you need it in y-intercept form)

2x+y=2 (if you need it in standard form)

Step-by-step explanation:

1. Write the original line in y=mx+b form. In other words, get the y by itself on the left side of the equation.

Subtract 2x from both sides.

y=-2x+1

2. Recall that parallel lines have the same slope. Slope is always the number with the x in the equation. Since the slope in the first equation is -2, the slope of the new line will also be -2.

3. Find the y-intercept. Use the point (-1,4) and plug the y and x values into the point-slope formula. M represents the slope.

y-y1=m(x-x1)

y-4=-2(x+1)

Simplify the equation.

y-4=-2x-2

y=-2x+2

(Proceed to step 4 if you need it in standard form)

4. Write the equation in standard form (x+y=z). Z represents the number by itself without variables.

Add -2x to both sides

2x+y=2

Answer:

An of line that passes through the point (−1,4) and is parallel to the line will be:

Step-by-step explanation:

We know that the slope-intercept form of the line equation

y = mx+b

where m is the slope and b is the y-intercept

Given the line

2x+y=1

converting the line into slope-intercept form

y = -2x+1

comparing with the slope-intercept form of the line equation

The slope of the line = m = -2

We know that the parallel lines have the same slopes.

Thus, the slope of line that passes through the point (−1,4) and is parallel to the line will be: -2

using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values of the slope = -2 and the point (-1, 4)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-4=-2\left(x-\left(-1\right)\right)[/tex]

Add 4 to both sides

[tex]y-4+4=-2\left(x+1\right)+4[/tex]

[tex]y=-2x+2[/tex]

Therefore, an of line that passes through the point (−1,4) and is parallel to the line will be:

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

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

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.

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=....

Step-by-step explanation:

By using Elimination method

Multiply equation 1 by 9 and equation 2 by 3/2

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

Step-by-step explanation:

in order to simplify divide the numerator and denominator by the greatest Common Factor or both numbers... in this case the numbers are 6 and 8

6: 1,2,3,6

8:1,2,4,8,

as you can see the GCF is 2... so you divide 6 by 2 nd 8 by 2

6/2= 3

8/2=4

since 6 in ur numerator the quotient is 3 so the number 3 goes on the top
