Answer:
1/4n - 3
Step-by-step explanation:
1/4 of a number means multiplying 1/4 to n. So we can write 1/4n. Now we write the subtract 3 portion. 1/4n - 3.

Answer:
π
Step-by-step explanation:
Solve for x on the interval [0, 2pi]
Given the equation
Sinx = cosx + 1
Square both sides of the equation
Sin²x = (cos x + 1)²
Sin²x = cos²x + 2cos x + 1
Since Sin²x = 1 - cos²x
1 - cos²x = cos²x + 2cos x + 1
Collect like terms
1-1-cos²x-cos²x-2cos x = 0
-2cos²x-2cos x = 0
-2cos²x = 2cos x
-cosx = 1
cos x = -1
x = arccos -1
x = 180 degrees
<em>Hence the value of x = π</em>
Answer:
Step-by-step explanation:
Is this graphing? If so, remember the formula: y=mx+b
If it's y=-1/3x+1, then 1 is your slope intercept
Place the dot on your graph where 1 is on your y-intercept.
Graphing -1/3x is just like rise over run, positives go up then right, (If 1/3 was graphed you would go 1 pixel up then 3 to the right.)
Since -1/3x is a negative, you're going down 1, left 3. It should give you a line that is coming from the top of the graphing box to the bottom.
If you want, create a table for x and y. If 0 was your x, then your y is 1, this is because theres a +1 in your equation.
If 3 was your x, then your y would be 0, because -1/3(3) + 1 is 0.
Given:
The point is (-2,4).
To find:
Whether the point (-2,4) satisfy 
or 
.
Solution:
We have a point (-2,4).
Substituting x=-2 in 3x+5 and check whether it is greater, equal or less than y value, i.e., 4.
-1 is less than 4.
In can be written as
Therefore, the given point (-2,4) satisfy .
