Answer:
B. y=sin(x) and y=-1/2
Step-by-step explanation:
We have been given the following trigonometric inequality;
2sin(x)=>-1
The above inequality can be re-written as;
sin(x)=>-1/2
after dividing both sides by 2.
We can then formulate two separate equations, one containing the expression on the right hand side and the other containing the expression on the left hand side;
From the left hand side we form the following equation;
y = sin(x)
From the right hand side we form the following equation;
y = -1/2
Therefore, the above two equations can be graphed to help solve the given trigonometric inequality
Since they are FEWER than 30 total cones, the sum of x small cones and y large one must be LESS THAN 30: x+y <30
He needs AT LEAST a dozen (12), so that means that 12 will work or more than 12:
Hello,
John : n
Brad : n + 12
n + n + 12 = 84
2n + 12 = 84
2n = 84 - 12
2n = 72
n = 72/2
n = 36
John $36 and Brad $36 + $12 = $48
