Two lines, A and B, are represented by equations given below: Line A: y = x − 4 Line B: y = 3x + 4 Which of the following shows the solution to the system of equations and explains why? (1 point) a (−3, −5), because the point satisfies one of the equations b (−3, −5), because the point lies between the two axes c (−4, −8), because the point satisfies both equations d (−4, −8), because the point does not lie on any axis

Answers

Answer 1

Answer:

The answer is "C"

Step-by-step explanation:

Answer 2

Answer:

Answer C.  This point lies between the two axes and its coordinates satisfy both equations

Step-by-step explanation:

Line A: y = x − 4

Line B: y = 3x + 4

Let's actually solve this system, using substitution:  Equate

Line A: y = x − 4   to   Line B: y = 3x + 4, obtaining:

                  x − 4  =     3x + 4

Subtract (x - 4) from both sides.  Doing so yields

                         0 = 2x + 8, and so x = -4.

From Line A let's find y:   Letting x = -4, we get:  y = -4 - 4 = -8

and so the solution is (-4, -8).  This matches Answer C.  This point lies between the two axes and its coordinates satisfy both equations.

"Explain why the solution of a system of linear equations is the point of intersection of their graphs"
Can you please explain this to be in a simpler form?

Answers

Answer:

Step-by-step explanation:

The solution of a system of linear equations is the point of intersection of their graphs because the intersection represents the only x or y values that will satisfy both/all equations. The graph visually shows that the intersection of these equations is the only spot on the graph that all of the equations have in common. This means that only this spot will satisfy all equations. For example, the intersection may be (0,1); this means that for all equations an x value of 0 will always result in the y value of 1. However, an x or y value that satisfies one equation may not satisfy the others if they do not lead to the desired outcome.

PLZ, QUICKLY IT IS HOMEWORK Two trains leave the same station at the same time, but are headed in opposite directions. One train travels at 70 mph and the other train travels at 80 mph. How long after they leave the station will they be 50 km apart?

Answers

Answer:

20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart, if the Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 km/hr and the other travels at an average speed of 70 km/hr.

Step-by-step explanation:

The given is,

                  One train travels at an average speed of 80 km/hr

                  The other travels at an average speed of 70 km/hr

Step:1

     Formula to calculate the distance traveled by two trains,

     Distance traveled by two trains = (Rate of speed of train one +

                                                          Rate of speed of other train) × Time

        From the given the above equation becomes,

        Let, h = Time taken to each the distance

                                         50 = ( 80 + 70 ) h

                                           50 = (150) h

                                             

                                                 = 0.3333 hours

                                                 = ( 0.333 × 60 )          ( ∵ 1 hr = 60 minutes )

                                               h = 20 minutes

Step:2

           Check for solution,

           From equation (1),

                          50 = ( 80+70 ) (0.3333)

                          50 = (150)(0.3333)

                          50 = 50

Result:

         20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart.

Find the area of the figure.

Answers

if i’m not mistaken it should be 55 because if you find the area of the whole triangle and subtract the mini rectangle you should get the shape
i’m pretty sure the answer is 15. this is because i split the triangle into 2 parts, then i multiplied 5x4 for the first triangle which equals 20, but then u have to divide it by 2 bc the formula for a triangle is A=1/2 (b x h) so then the answer for the first triangle is 10. now you have to do it to the other little triangle which gives u 5. at this point you have to add 10+5 which gives you 15. therefore the answer for this question is 15. i hope this helps!

Answers

Mode: value that occurs most
Mean: average (add all values then divide by the amount of number)
Median: middle number

Mode: 80 (appears the most)
Mean: 95 + 80 + 80 + 85 + 80 + 85 + 90 = 595/7 = 85, the mean is 85
Median first put them in order
80, 80, 80, 85, 85, 90, 95
The median is the middle which is 85

Which statement matches?

Solution: D

Answer: D (Mean is 85)

Explanation:

"The list below shows the quiz scores for a group of students.

95, 80, 80, 85, 80, 85, 90"

The choices talk about median and mode so we find those first:

Median: find by taking which is the middle number when the data is from low to highest

1) rearrange them from low to high

80, 80, 80, 85, 85, 90, 95

2) find middle number

80, 80, 80, 85, 85, 90, 95

The median is 85

Mean: mean is the average of all numbers. Find by adding numbers and dividing by amount of numbers

1) add 80, 80, 80, 85, 85, 90, 95 and get 595

2) There are 7 total numbers so do 595/7 = 85

The mean is 85

D is the correct answer

why?

A is wrong because they are 85 not 80

B is wrong because it is 85 not 80

C is wrong because it is 85 not 80

D is right because it is 85!
