Answer:
x=0
Step-by-step explanation:
You can combine the equation to get 2sin(3/2 +x) = -2
divide both sides by 2 and you get the equation equal to -1. sin is equal to -1 when the value inside is 3/2 so this is the answer.
Answer: infinite
Step-by-step explanation: since they have the same slope and y interscept it is a coincident line and has infinite solutions
y= 4-x
y= 4-x
The first one is 4
Second is 5/9
Third is 1/2
Fourth is 11
7/10x - 5 = 1/2x
7/10x - 1/2x = 5
7/10x - 5/10x = 5
2/10x = 5
x = 5 / (2/10)
x = 5 * 10/2
x = 50/2
x = 25 gallons <===
