Two systems of equations are shown below:

system a
6x + y = 2
2x − 3y = −10
system b
−x − y = −3
−x − y = −3
which of the following statements is correct about the two systems of equations? (5 points)

group of answer choices

the value of x for system b will be 4 less than the value of x for system a because the coefficient of x in the first equation of system b is 4 less than the coefficient of x in the first equation of system a.

they will have the same solution because the first equations of both the systems have the same graph.

they will have the same solution because the first equation of system b is obtained by adding the first equation of system a to 4 times the second equation of system a.

the value of x for system a will be equal to the value of y for system b because the first equation of system b is obtained by adding −4 to the first equation of system a and the second equations are identical.

The solution of the equations in system A is,

(x,y) = (-0.8 , 2.8)

The system of equation B contains 2 identical equations or only 1 equation which will be represented by a straight line and will have infinite no. of solutions.

Step-by-step explanation:

The equations in system A are,

6x + y = -2 -----------------(1)

2x - 3y = -10 ---------------(2)

Doing    we get,

20x = -16

⇒ x = - 0.8 --------------------(3)

From (3) putting the value of x in  (1) we get,

y =

  = 2.8 -----------------------(4)

So the solution is, (x , y) = (-0.8 , 2.8)

The system of equation B contains 2 identical equations or only 1 equation which will be represented by a straight line and will have infinite no. of solutions.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
