Answers

Answer 1

Answer:

a. 8,953.5 seconds

b. 14,400 seconds (check note)

Step-by-step explanation:

y=-4x

y=-35814 (negative because this is underwater)

-35814=-4x

8953.5

The model suggests it would take 8,953.5 seconds for DeepSea Challenger to reach the bottom (2.487083333 hours, or about 2 hours and 30 minutes).

y=4x

x=3600 (positive because the vessel is rising)

4(3600)

14400

It took 14,400 seconds for the DeepSea Challenger to ascend to the surface.

[also note: I'm not sure if the second question is asking for how many seconds it takes to ascend to the surface with reference to the 4 seconds in the previous question (which is how I answered part b) or if it's asking how many seconds 1 hour is, and in that case. the answer is 3,600 seconds. I hope this helps and sorry if it's unclear!]

2.) 4a+2c=5000
3.) 4a-2c=5000
4.) a+c=1600
WILL GIVE BRAINLIEST TO ANY CORRECT ANSWER!!!!!

Answers

Answer:

2. 4a+2c = 5000

4. a + c = 1600

Step-by-step explanation:

Answer:

2.) 4a+2c=5,000

4.) a+c=1,600

Step-by-step explanation:

4 times a(adults) plus 2 times c(children)=5,000

4 is from $4 per adult(a) and 2 is from $2 per children(c).

a+c=1,600

You can add the number of adults and children to find the answer.

Line segment AC and BD are parallel. What are the new endpoints of the line segments AC and BD if the parallel lines are reflected across the x-axis?

A. A'(-2, 5) C'(5, 1) and B'(-2, -4) D'(5, 0)
B. A'(-5, -2) C'(-1, 5) and B'(-4, -2) D'(0, 5)
C. A'(2, -5) C'(-5, -1) and B'(2, -4) D'(-5, 0)
D. A'(5, 2) C'(1, -5) and B'(4, 2) D'(0, -5)

Answers

C. A’(2,-5) C’(-5,-1) and B’(2,-4) D’(-5,0)

Option C : A'(2, -5) C'(-5, -1) and B'(2, -4) D'(-5, 0) is correct.

We have two line segments AB and CD parallel to each other.

We have to find the new endpoints if the parallel lines are reflected across the x - axis.

How will you find the image of the point across the x - axis?

For a point P(x, y), its reflection across the x-axis is P'(x, -y).

From the figure - the coordinates of points A, B, C, D are -

[tex]A(2,5)\\B(2,4)\\C(-5, 1)\\D(-5, 0)[/tex]

We know the image of the point P(x, y) across the x-axis is P'(x,-y). Therefore, the coordinates of the points, when they are reflected across the x-axis are-

[tex]A(2,5) - > A'(2, -5)\\B(2, 4)- > B'(2, -4)\\C(-5, 1)- > C'(-5, -1)\\D(-5,0)- > D'(-5,0)[/tex]

Hence, Option C : A'(2, -5) C'(-5, -1) and B'(2, -4) D'(-5, 0) is correct.

How many solutions are there to this system of equations? On a coordinate plane, 2 lines have equations y = one-fourth (x minus 4) and y = one-fourth x minus 1.
a. one solution
b. no solution
c. infinitely many solutions
d. it cannot be determined without solving

Answers

Answer:

b. no solution

Step-by-step explanation:

y=1/4x-4

y=1/4x-1

This pair of equations has the same slope, meaning that they are parallel lines. Parallel lines never intersect so there is no result of solving this system of equations. Therefore, the correct answer would be b, that this system of equations has no solution.
