Look at the graph of a line segment before and after a transformation occurred,

Which statement describes the transformation that could have been made to the line segment?
A. The line segment was dilated by a factor of 1/2
B. The line segment was rotated 180° about the origin
C. The line segment was reflected over the x-axis
D. The line segment was translated 6 units down and 1 unit left

Answers

C !

It can't be A because the line does not change length. It's can't be B because if you imagine the movement of the line, when rotated the A and B points would switch side visually. It can't be D because the transformed line segment has not moved 1 unit left.

Answer:

x = 10, m∠TRS = 60°

Step-by-step explanation:

It is given that the total measurement of m∠QRS = 122°. Set the equation. Note:

∠QRS = ∠QRT + ∠TRS

Plug in the corresponding terms with the corresponding angles:

122 = 7x - 8 + 6x

First, simplify by combining like terms:

122 = (7x + 6x) - 8

122 = 13x - 8

Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtractions

~

First, add 8 to both sides of the equation:

122  = 13x - 8

122 (+8) = 13x - 8 (+8)

122 + 8 = 13x

130 = 13x

Next, divide 13 from both sides of the equation:

(130)/13 = (13x)/13

130/13 = x

x = 10

Next, plug in 10 for x for the measurement of m∠TRS

m∠TRS = 6x

m∠TRS = 6 (* 10)

m∠TRS = 60°

Answer: x = 10, m∠TRS = 60°

Answer:

D

Step-by-step explanation:

How do i does this linear equation in slope form

Answers

Answer:

y=2x+7

Step-by-step explanation:

We can substitute values x and y in the equations to see if it works in the equations.

For example, the first equation is y=-2x+6. Using the point (-3, 1), we know that 1 is the y value and -3 is the x value. So, 1 = -2(-3)+6

We can rearrange this is to get 1=12. This is false, so this can't be the right answer.

y=2x-1

1=2*-3-1 so 1=-7 which is also false

y=2x+7

1=2*-3+7 so 1=1 which is true!

We can use any of the points given to check that this equation works.

Hope this helps!

Answer:

y = 2x + 7

Step-by-step explanation:

Slope intercept form: y = mx + b

You will need to find the slope and y-intercept

First, find the slope: = y2 - y1 / x2 - x1

Given points: (-3, 1) (-2, 3)

m = 3 − 1 / −2 − −3

m = 2 / 1

m = 2

Slope is 2, now find the y-intercept

y = 2x + b  (Use point (-3, 1))

1 = 2(-3) + b

1 = -6 + b

b = 7

Equation: y = 2x + 7

Answers

Answer:

mean for a = 60/10 = 6

mad of a = 2

mean for b = 80/10 = 8

mad of b = 2

Step-by-step explanation:

Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Take each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set. The mean absolute deviation, MAD, is 2.

\frac {1}{n} \sum \limits_{i=1}^n |x_i-m(X)|

m(X) = average value of the data set

n = number of data values

x_i = data values in the set

mean = average.

Tell wether the angles are adjacent or vertical. Then find the value of x.

Answers

Answer:

The angles are vertical

Step-by-step explanation:

x+42+2x+1=180

put the like terms together i.e 2x+x+42+1=180

you get: 3x+43=180

Take 43 to th other side of 180 i.e 3x=180-43 i.e (180-43=137)

You get 3x=137

Divide both sides by 3

you get x=45.666666666667(Round off to get 45.67)

Substitute the value of x to the angles

x+42(45.67+42=87.67)

2x+1(2(45.67)+1=92.34

Add 87.67+92.34=180

THis shows that the angles are vertical

4 where chocolate bc if one was 20% that means that it was just 1/5 so 4/5 will be chocolate which indicates that’s 4 are chocolate
