Solve the system.

Mathematics
1 answer:
liraira [26]3 years ago
6 0

Answer:

Option D is right,.

Step-by-step explanation:

-a+4b+2c=-8   ... i

3a+b-4c=9      ... ii

b=-1                 ... iii

Substitute the value of b, in i and ii

-a-4+2c =-8 or -a+2c = -4

and 3a-1-4c = 9 or 3a -4c =8

Now we have two equations in two variables

-a+2c =-4 and 3a-4c =8

a = 2c+4:  substitute this in the other equatin.

3(2c+4)-4c =8 Or 2c +12 =8

2c =-4 or c = -2

Substitute in -a+2c =12

-a-2 = -4

a = -2+4 =2

a=2, b=-1 and c =-1 is the solution.

You purchase 26 “parking hours” that you can use over the next month to park your food truck at the fair. Weekday hours costs $2
Oksanka [162]

Answer: 5

Step-by-step explanation:

weekday hours x*2

weekend hours y*10

x+y=26

2x+10y=220

----------------------

x=26-y

2(26-y)+10y=220

52-2y+10y=220

8y=220-52

8y=168

y=168/8

y=21

x=26-21=5

x=5

What is the distance between points v (3,3) and w (-2,-3) round to the nearest tenth if necessary
Vinil7 [7]

Answer:

7.81 u

Step-by-step explanation:

<u>Given :- </u>

  • Two points (3,3) and (-2,-3) is given to us.

And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,

:\implies D = √{(x2-x1)² + (y2-y1)²}

:\implies D =√[ (3+2)² +(-3-3)²]

:\implies D =√[ 5² +6²]

:\implies D =√[ 25 +36]

:\implies D = 61

:\implies D = 7.81

<h3>Hence the distance between the two points is 7.81 units .</h3>
