Answer:
That's the right answer.
Step-by-step explanation:
2x+3=3x
Subtract 2x from both sides
3=x or x=3
3400 is 10 times greater than 340 because if you divide 3400 by 10, you will get 340. Letting you know that 3400 is 10(ten) times greater than 340.
The sine has a range -1 to +1 so y goes from 1+2(-1) to 1+2(1) = -1 to 3
Range: -1 ≤ y ≤ 3
Answer:
(8/5 , -2/5)
Step-by-step explanation:
x-y=2
2x+3y=14
-y=-x+2
y=x-2
2x+3(x-2)=14
2x+3x-6=14
5x-6=14
5x=8
x=8/5
y=(8/5)-2
y= -2/5
