The measure of Angle ABD = measure of Angle ABC + measure of Angle CBD
Answer:
See below.
Step-by-step explanation:
For each size, divide the cost by the amount. Make sure the amounts are all in the same units. Then, the lowest cost per unit is the best buy.
The formulas are already given, all you have to do is plot them each separately and you will find that they crooks each other, the point of intersection is your solution.
To solve you can use inverse operations.
Here are the steps to find the answer:
1. Write out the equation: -6(x-2)+3x= -3(x+3) +21
2. Distribute both sides: -6x+12+3x= -3x-9+21
3. Simplify both sides: -3x+12=-3x+12
4. This equation is true for all values, or infinity, because the equation is the same on both sides
Let me know if you need further explanation. I hope this helps.
Answer:
Step-by-step explanation:
sin^2x=1/2
so sinx=1/V2=V2/2
x=pi/4
