Figure ABCD is transformed to figure A prime B prime C prime D prime, as shown: A coordinate grid is shown from negative 5 to 0 to 5 on both x -and y-axes. A polygon ABCD has A at ordered pair 1, 3, B at ordered pair 3, 4, C at ordered pair 2, 1, D at ordered pair 1, 1. A polygon A prime B prime C prime D prime has A prime at ordered pair negative 3, 3, B prime at ordered pair negative 5, 4, C prime at ordered pair negative 4, 1, D prime at ordered pair negative 3, 1. Which of the following sequences of transformations is used to obtain figure A prime B prime C prime D prime from figure ABCD? (1 point) Reflection about the x-axis followed by a translation to the right by 2 units Reflection about the y-axis followed by a translation to the left by 2 units Counterclockwise rotation by 90 degrees about the origin followed by a translation to the right by 2 units Counterclockwise rotation by 90 degrees about the origin followed by a translation to the left by 2 units

Answer:

i need this answer too

Answer:

The appropriate choice is the 2nd one ...

... Reflection over the y-axis followed by a translation down by 5 units.

Step-by-step explanation:

The transformed figure has the opposite orientation (A'B'C'D' is counterclockwise, whereas ABCD is clockwise), so a reflection is involved. The sgment C'D' is still at the bottom, as is CD, so the reflection must be across a vertical line.

In the attached, the light-blue figure A''B''C''D'' shows the reflection of ABCD across the y-axis. It is easy to see that figure A'B'C'D' is a translation of that 5 units downward.

The appropriate choice is the 2nd one ...

... Reflection over the y-axis followed by a translation down by 5 units.

Find k if X=2 and y=1 is a solution of 2x-8y+k/2=0​

Answers

Answer:

k=2

Step-by-step explanation:

2x-8y+k/2=0

puting the values of x and y

2*2-8*1+k/2=0

4-8+k/2=0

-4+k/2=0

k/2=4

sing changes if side changed

k=4/2

k=2

We first substituted the X and Y in the equation, so 2 instead of X and 1 instead of Y.

Then I moved the K to make it the subject of the equation by algebra which gave me a -K, but I want k not negative k so I multiplied everything by -1 because, -1 × -1= +1 so K=2.

Answer:

7.4

Step-by-step explanation i took the test

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

x - x/2 - 6.8 = -3.1

x = 7.4

The temperature at the beginning of the day was 7.4°F.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The temperature at the beginning of the day = x

The temperature during the day = x/2

The temperature after the sun goes down = 6.8°F

The temperature at the end of the day = -3.1°F

Now,

We can write an expression as,

x - x/2 - 6.8 = -3.1

x - x/2 = -3.1 + 6.8
x/2 = 3.7

x = 7.4°F

Thus,

The temperature at the beginning of the day was 7.4°F.

three angles of a quadrilateral are 34°, 70° and 126°. find the measure of the fourth angle. ​

Answers

Answer:

130 will be correct answer

Step-by-step explanation:

The three angles are

34° 70° and 126°

we have to find fourth angle

let us consider fourth angle as X

The sum of quadrilateral is 360°.

So

34°+70°+126°+ x = 360°

130+X =360°

X = 360°-130°

X = 230°

Here we got the fourth angle
