Could you retake the photo plz so i can see the full question and answer choices

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:

X=28/9, Y=7/5

Step-by-step explanation:

By using Elimination method

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

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:

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=-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:

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:

3/4

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

3/4

Answer: 3/4 or .75

Explanation:

Step-by-step explanation:

Answer:

39 cm

Step-by-step explanation:

Given

ΔABC and ΔA'B'C'

B = 5 cm

B' = 15 cm

Perimeter ΔABC = 13 cm

Required

Determine the perimeter of ΔA'B'C

[Since ΔABC is dilated to give ΔA'B'C', the first step is to get the scale factor.]

Scale Factor = ΔA'B'C ÷ ΔABC

[Using side B and B' as points of reference]

Scale Factor = B' ÷ B

[Substitute values for B' and B]

Scale Factor = 15 ÷ 5

Scale Factor = 3

[The perimeter of ΔA'B'C' is then calculated as:]

Perimeter ΔA'B'C'= Scale Factor * Perimeter of ΔABC

ΔA'B'C = 3 * 13 cm

ΔA'B'C = 39 cm
