You are the lucky winner because you have found this answer. Have a good day.

The red triangle A is reflected across the y-axis onto triangle D, the blue triangle D is reflected across the x-axis onto triangle C and the green triangle C is reflected across the line y = –x onto triangle A. Then the correct options are B, C, and E.

A point, line, or mathematical figure can be converted in one of four ways, and each has an effect on the object's structure and/or position.

The reflection does not change the shape and size of the geometry. But flipped the image.

Let's check all the options. Then we have

A.The red triangle A is reflected across the x-axis onto triangle B. Incorrect, because the orientation is different.

B.The red triangle A is reflected across the y-axis onto triangle D. Correct.

C.The blue triangle D is reflected across the x-axis onto triangle C. Correct.

D.The blue triangle D is reflected across the line y = x onto triangle B. Correct, because the orientation is different.

E.The green triangle C is reflected across the line y = –x onto triangle A. Correct.

The red triangle A is reflected across the y-axis onto triangle D, the blue triangle D is reflected across the x-axis onto triangle C and the green triangle C is reflected across the line y = –x onto triangle A. Then the correct options are B, C, and E.

please mark as brainliest

Answer:

Step-by-step explanation:

It is an integer because integers are whole numbers. This means that it doesn't include decimals, fractions, and irrational numbers. Even though not all negative numbers are integers, this one is, and that is because it is not a decimal, fraction, or irrational number.

Write the numerator and denominator with a common denominator. Then divide the numerator by the denominator. To do this, multiply the numerator by the reciprocal of the denominator.

Step-by-step explanation:

Simplifying an expression involves breaking down the expression.

The true statement is: (a) Write the numerator and denominator with a common denominator. Then divide the numerator by the denominator. To do this, multiply the numerator by the reciprocal of the denominator.

The expression is given as:

[tex]\mathbf{\frac{\frac{5}{a -3} - 4}{ 2 + \frac{1}{a - 3}}}[/tex]

Start by writing the numerator and the denominator, with a common denominator

[tex]\mathbf{\frac{\frac{5}{a -3} - 4}{ 2 + \frac{1}{a - 3}} = \frac{\frac{5 -4a +12}{a - 3}}{\frac{2a - 6 + 1}{a - 3}}}[/tex]

Cancel out the denominators of both fractions (by dividing the numerators)

[tex]\mathbf{\frac{\frac{5}{a -3} - 4}{ 2 + \frac{1}{a - 3}} = \frac{5 -4a +12}{2a - 6 + 1}}[/tex]

So, we have:

[tex]\mathbf{\frac{\frac{5}{a -3} - 4}{ 2 + \frac{1}{a - 3}} = \frac{17 -4a }{2a - 5}}[/tex]

Hence, the correct option is (a).

m= yo

your slope

Step-by-step explanation:

Answer:

The equation of the line that passes through the points (-1,8) and (2,-4) is:

Step-by-step explanation:

Given the points

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-1,\:8\right),\:\left(x_2,\:y_2\right)=\left(2,\:-4\right)[/tex]

[tex]m=\frac{-4-8}{2-\left(-1\right)}[/tex]

[tex]m=-4[/tex]

As the point-slope form of the line equation is

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

where m is the slope.

substituting the values m = -4 and the point (-1,8)

[tex]y-\(8\right=-4\left(x-\left(-1\right)\right)[/tex]

[tex]y-8 = -4(x+1)[/tex]

Add 8 to both sides

[tex]y-8+8=-4\left(x+1\right)+8[/tex]

[tex]y=-4x+4[/tex]

Therefore, the equation of the line that passes through the points (-1,8) and (2,-4) is:

Answer:

y = 5x/4 + 10

Step-by-step explanation:

If two lines are parallel, the slopes are equal

The equation of a straight line is y = mx + c

where m is slope and c is y-intercept

So in this case 5/4 is also the slope m of the second line

we can write the equation as;

y-y1 = m(x-x1)

y-0 = 5/4(x + 8)

y = 5x/4 + 10

Answer:

x=-27

Step-by-step explanation:

-27 = x

Answer: <1 is 46

Step-by-step explanation: If 4x+10+2x-16=180 becuase they are same sided interior angle they have to equal 180. and if you do the process you get X=31 and if you plug it in you get <1=46 and to check it you have to plug it in the other and add thoses two up and see if you get 180. which it does.

Answer:

The question, in the slope-intercept form will be:

Step-by-step explanation:

Taking the two points on the line to find the slope

(0, 0)

(4, 4)

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(4,\:4\right)[/tex]

[tex]m=\frac{4-0}{4-0}[/tex]

[tex]m=1[/tex]

As the point-slope form is

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

where m is the slope

substituting the values m = 1 and the point (0, 0)

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

[tex]y-0=1(x-0)[/tex]

[tex]y=x[/tex]

As the slope-intercept form is

[tex]y=mx+b[/tex]

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

so writing the equation in slope-intercept form

[tex]y=x[/tex]

[tex]y=1(x)+0[/tex]

Therefore, the question, in the slope-intercept form will be:

Answer:

You sold 15 cookies and 12 muffins

Step-by-step explanation:

So you're given that 1 cookie is sold for $3 and 1 muffin is sold for $7

You're also given that in total you made $129, and sold 27 items

Let's make equations from that, letting c stand for amount of cookies and m for amount of muffins.

Now we can use the second equation to find m:

c + m = 27

m = 27 - c

Not we can substitute m into the first equation to find c:

3c + 7m = 129                  

3c + 7(27-c) = 129            [substitute m for (27-c)]

3c + 189 -7c = 129           [distribute 7 into (27-c)]

-4c + 189 = 129                [combine like terms]

-4c = -60                          [subtract 189 from both sides]

c = 15                               [divide both sides by -4]

Now we can substitute c into the second equation to find m:

c + m = 27

15 + m = 27

m = 12

bring the 7 over.

to do so you must subtract 7 from itself (canceling it out), then also subtract it from 8.

now you have -x=1.

divide -x by -x (or -1) which just gives you positive x.

Answer:

4.39 to 2DP.

Step-by-step explanation:

x * (x - 2) =  28

x^2 - 2x = 28

Solving by completing the square:

(x - 1)^2 - 1 = 28

(x - 1)^2 = 29

x = +/-√29 + 1

x = 6.38516, -4.38516

x must be positive so it = 6.38516.

The shortest side = x - 2 = 4.385.
