Step-by-step explanation:
First, make sure that all the variables are in one side. The first equation is gonna be x-y=3
Second, we are going to eliminate the y because it is much easier, but you can also eliminate the x
We have to add both equation because the y in the first equation is negative and in the second equation it’s positive.
We are left with 3x=9
Therefore, x=3
Last, substitute x= 3 in one of the equations
Y=6
P.O.I is (3,6)
Answer: see proof below
<u>Step-by-step explanation:</u>
Given: cos 330 = 
Use the Double-Angle Identity: cos 2A = 2 cos² A - 1
Proof LHS → RHS:
LHS cos 165
Double-Angle: cos (2 · 165) = 2 cos² 165 - 1
⇒ cos 330 = 2 cos² 165 - 1
⇒ 2 cos² 165 = cos 330 + 1
Given: 
Divide by 2: 
Square root: 
Scratchwork: 
Since cos 165 is in the 2nd Quadrant, the sign is NEGATIVE
LHS = RHS 
Answer:
His monthly sales goal if he budgets $3750 as his monthly income is $15000.
Step-by-step explanation:
From the information given, the formula to calculate the salary that Ron earns would be:
Total salary=1500+0.15*(monthly sales)
Now, you can replace the total salary and he budgets $3750 as his monthly income and solve for the monthly sales:
3750=1500+0.15*(monthly sales)
3750-1500=0.15*(monthly sales)
monthly sales=2250/0.15
monthly sales=15000
According to this, the answer is that his monthly sales goal if he budgets $3750 as his monthly income is $15000.
