Answer 2

is the correct answer no solution?

Answer 3

im not sure i forgot how to do these man

Answer 4

ohh can you @someone who can?

Answer 5

is it no solutions?

Answer 6

Multiply the top by -4:
-4x+-8y=13(-4)

Samantha is going on vacation for the summer and is trying to choose between two different plans. The first plan costs $450 for 3 days at a hotel and 2 days at an amusement park. The second plan offers 5 days at the same hotel and 3 days at the amusement park for $700. The cost of 1 day at the hotel and the amusement park is the same under both plans. How much does a 1 day trip to the amusement park cost?

I belive this answer to be 150 dollars

Sorry, can't do word problems at the moment.

Answer 12

okay number problem?

Answer 13

x-3y=-6
2x-7y=10
find y

Answer 14

i mean solve for y in the first equation

Answer 15

First equation? It's y=(x/3)+2

Answer 16

so its 1/3x +2 ?

Answer 17

Could be written either way. but ,make sure that x is not in the denominator.

Answer 18

k :)

Answer 19

Answer 34

no they are no linear equation here they are

Answer 35

._.

Answer 36

lol pretty please :)

Answer 37

For the system of equations problems just graph them and see where they intersect.
