Christo graphs AB with endpoints A( -3, -2 ) and B ( -1, -2 ) what are the endpoints of the image after a reflection of AB across the x axis?

1. (-3,2) and (-1,2)

2.(-3.-2) and (-1,-2)

3. (1,-2) and (3,-2)

4. (2,3) and (2,1)

5. none of the above

Answers

Answer 1

Answer:

1. (-3,2) and (-1,2)

Step-by-step explanation:

Reflection over x-axis results in coordinate change as follows:

(x, y) → (x, -y), x-coordinate stays as is and y-coordinate changes its sign to opposite

Given points:

A(-3, -2) and B(-1, -2)

The image of AB will have coordinates:

A'(-3, 2) and B'(-1, 2)

Correct choice is 1.

Answer 2

Answer:

(-3,2) and (-1,2)

Step-by-step explanation: I took the test already and got this correct crazy to find  this question 2 days later.

what is the answer to 4(x + 1) = 4x + 10

Answers

Answer:

No solution

Step-by-step explanation:

First we would have to see if anything has to be distributed and yes the 4 in the expression 4(x + 1) has to be distributed to the x and 1. So we would multiply the 4 by x and 1. Now we have 4x + 4 = 4x + 10. We have to get the x's on 1 side of the equation so we would do the inverse of one of the x's and we can only subtract. So we can subtract 4x on both sides. So now we have

4 = 10. That isn't a correct statement so there is no solution.

4 does not equal 10.

Solve for y.
ln(2y−1)=3

Answer y=(e^3+1/2)

for future reference

Answers

Answer:

The correct answer should be:

[tex]y=\frac{1}{2}(e^3+1)\text{ or } y=\frac{e^3}{2}+\frac{1}{2}[/tex]

Step-by-step explanation:

We have the equation:

[tex]\ln(2y-1)=3[/tex]

Let’s remove the natural logarithm by raising both sides to e. This yields:

[tex]e^{\ln(2y-1)}=e^3[/tex]

The left will simplify to:

[tex]2y-1=e^3[/tex]

Add 1 to both sides:

[tex]2y=e^3+1[/tex]

Divide both sides by 2. So, the value of y should be:

[tex]y=\frac{1}{2}(e^3+1)[/tex]

Answer:

The correct answer is indeed y = [tex]\frac{e^3+1}{2}[/tex]

=1

The value of (f o g)(-1) is 1 if the function f(x) =  8/(x + 2) and g(x) = 4x² + 2 the answer is 1.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have:

Two functions:

f(x) =  8/(x + 2)

g(x) = 4x² + 2

g(-1) = 4(-1)² + 2

g(-1) = 4 + 2

g(-1) = 6

f(g(-1)) = 8/(x + 2)

f(g(-1)) = 8/(6 + 2)

f(g(-1)) = 8/8

f(g(-1)) = 1

Thus, the value of (f o g)(-1) is 1 if the function f(x) =  8/(x + 2) and g(x) = 4x² + 2 the answer is 1.

Step-by-step explanation:

The picture gives us that two sides are congruent. We can see that an angle is congruent as well because they share a common point at their tip.

If we look at just the area of intersection, it looks like an X. Think of the X as two lines intersecting. Each side equals 180°, and because both triangles are made up of those sides, we can conclude that the angles are congruent as well.

William left his house at time zero and drove to the store, which is 8 blocks away, at a speed of 2 blocks per minute. Then he stopped and went into the store for 2 minutes. From there, he drove in the same direction at a speed of 4 blocks per minute until he got to the bank, which is 16 blocks away from the store. He stopped at the bank for 5 minutes. Then he drove home at a speed of 12 blocks every minute. Make a graph showing the number of blocks away from home that William is x minutes after he leaves his house, until he get back home.

Answers

Answer:

17 minutes

Step-by-step explanation:

First distance in blocks and time.

x1= 8 b and t1 = 4 min

Second distance in blocks and time.

x2= 8 b and t2 = 6 min

Third distance in blocks and time.

x3= 24 b and t3 = 12 min

Fourth distance in blocks and time.

x4= 24 b and t4 = 17 min

Final distance in blocks and time.

x5= -24 b and t5 = 19 min

The first trap Willian is 8 blocks from home, we know that the speed is 2 b/min (blocks per minute). Using the definition of speed V1 = x1/t1 we can find t1. t1 will be t1 = 8/2 = 4 min.

He spends 2 minutes, so t2 = 6 min.

Now, the new speed is V2=4 b/min and go to the bank that is 16 blocks away from store, so x2 = 16 + 8 = 24 b. Times will be t = 24/4 = 6 min. But we need to add to t2 to get the total time. t3 = 6 + 6 = 12 min.

He spends 5 minutes here, so t4 = 12 + 5 = 17 min.

Finally, he drove home at -12 b/min, so the time to get home will be:

t = 24/12 = 2 min. Therefore, the total time t5 = 17 + 2 = 19 min.
