3x+2y=11
y=5x-1
Substitute the y in the first equation:
3x+2(5x-1)=11
y=5x-1
3x+10x-2=11
y=5x-1
13x=13
y=5x-1
Now substitute the x to find the y:
x=1
y=5-1=4
Answer:
The y coordinates become the opposite of what they already are.
Step-by-step explanation:
Example: (3,2) -> (3,-2). (-4, -7)-> (-4,7)

Answer:
as we know Sara need 8 tube in 3 experiment
she will use 2 tube in 1 experiment
now she have 6 tube in other experiments
so the question said to find how many tube were used in both experiment equally so 3,3 test tube were needed for each of the other two experiment
Step-by-step explanation:
total tube=8 (3 experiment)
used =2tube (1 experiment)
remaining=8-2=6
now ,
dividing 6 into 2 equal part
so,=6/2=3
so 3 tube were used in 2nd experiment and 3in 3rd experiment
Answer:
Oceans and the Sun.
Step-by-step explanation:
Lakes and the sun is also a good answer, but the question is asking which interact the <em>most</em>, which is the ocean and sun.
We can also rule out the moon since it has nothing to do with the water cycle, so the last two options are also wrong.
