Answer:

a = -5

Step-by-step explanation:

2(a + 3) = -4

2a + 6 = -4     Use the distributive property, distribute the 2 into (a + 3), meaning multiply the 2 by a and by 3.

2a = -10       Subtract 6 from both sides to isolate the a variable.

a = -5        Divide both sides by 2

Answer: a = -5

Step-by-step explanation:

2(a+3)=-4

Distribute

2a+6=-4

subtract the six with the four and you get -10

-6-4=-10

now divide 2a with -10

you get a= -5

you can plug the answer in

C) they are parallel

as the slopes must be equal due to the fact they are both perpendicular to line n ( for a perpendicular line you flip the slope and change the sign , so both of them being perpendicular to n the slopes must be equal)


They cant interest at all since they are perpendicular and they may not be the same line

zhuklara [117]

Answer:

Check the solution in both equations. The solution is ( − 1, 2). Solve the system by graphing: {− x + y = 12 x + y = 10 . Solve the system by graphing: {2x + y = 6 x + y = 1 . In all the systems of linear equations so far, the lines intersected and the solution was one point.

Hope it helps!!!

39 miles. If d=rt and the rate is 16 mph and the time is 3 hours then 16 times 3 gives the distance of 39 miles. I could be wrong but that is what I would have done. I’m not sure if there are answer choices or not

gulaghasi [49]

Answer:

1.60 L of 10% solution

0.40 L of 35% solution

Step-by-step explanation:

If x = amount of 10% saline solution, and y = amount of 35% saline solution, then:

x + y = 2

0.10x + 0.35y = 0.15(2)

Solve with substitution:

0.10x + 0.35(2 − x) = 0.15(2)

0.10x + 0.70 − 0.35x = 0.30

0.40 = 0.25x

x = 1.60

y = 0.40
