For the translation, I believe it would be:
First; a reflection over the Y axis and the new points would be A(4,4) B(2,2) C(2,-1) D(4,1). (The Y value should be the same and the X axis should be the opposite)
Second; It should be moved three units down to get the points that A’ B’ C’ and D’ lie

I *think* they are congruent. I forgot what it exactly means, but they still have the same shape size and have all the same angles.

Hope this helps.

What is the equation of this line? Please help I will give extra points and the brain thing.

y=−3x−4/3

y=4/3x−3

y=3/4x−3

y=−3x−3/4

Answers

The equation of this line is y= 3/4x - 3
Because the y intercept is -3 and the slope is rise 3 run 4 making it 3/4. It is a increasing line so it has a positive slope
y=3/4x -3. You find the slope which is rise 3 and run 4 so it’s 3/4. Then the y intercept is already given to you since it’s just where the slope crosses the y axis. Y intercept is -3.

Please select the best answer from the choices provided


A
B
C
D

Answers

I think it letter C
Negative 2 so it means -2
Then to 4 so
(-2,4)
Then 0 to 0. So
(-2,4), (0,0),
Then 2 to 4
So
{(-2,4),(0,0),(2,4)}

The ordered pairs are, (-2, 4), (0, 0), (2, 4).

Option C is true.

Here,

Given that;

In a relation an arrow goes from -2 to 4, 0 to 0, 2 to 4.

We have to find ordered pairs.

What is Ordered pairs in set?

A function f from a set A to a set B is a set of ordered pairs {(x, y)} such that x is in the set A and y is in the set B.

(x, y) is an ordered pair in f.

Where, for every x ∈ A there is exactly one y ∈ B.

Now,

In a relation an arrow goes from -2 to 4, 0 to 0, 2 to 4.

Hence, by definition of ordered pairs;

We get the ordered pairs,

(-2, 4)

(0, 0)

(2, 4)

Hence, The ordered pairs are, (-2, 4), (0, 0), (2, 4)

Option C is true.

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.

In which step did the student first make a mistake and how can it be corrected?
Step 1; it should be m∠m + m∠n + m∠o = 180 degrees (sum of angles in a triangle)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
Step 2; m∠p − m∠o = 90 degrees (alternate interior angles)

Answers

Answer:

Step 1: It should be m∠m + m∠n + m∠o = 180° (sum of angles in a triangle)

Step-by-step explanation:

He made the mistake in Step 1: m∠m + m∠n + m∠p = 180°

It should be m∠m + m∠n + m∠o = 180°

Then only, he can equate it with m∠o + m∠p in step 3.

So,  m∠p is the exterior angle and m∠m and m∠n are the two remote interior angles.

m∠o is the adjacent angle to m∠p. They form a linear pair.

Hence, the correct answer is Step 1.

⇒ t = 75

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or variable raised to the power one.

We have to given some steps of equation.

Now, The complete steps to solve the equation are;

1/5t + 2 - ____ = 17 - _____

Subtract 2 from both sides;

⇒ 1/5t + 2 - 2 = 17 - 2

⇒ 1/5t = 15

Multiply 5 in both sides;

⇒ 5 * 1/5t = 5 * 15

⇒ t = 75

So, The complete steps are;

⇒ 1/5t + 2 - 2 = 17 - 2

⇒ 1/5t = 15

⇒ 5 * 1/5t = 5 * 15
