<h3>I'll teach you how to find the period of f(x)=sin(x)</h3>
-------------------------------------------------------
A period of a sin is is the length of one cycle.
The original period of the sine curve is 2π.
If x is multiplied by a constant that can change the answer of the period.
The period of the basic sine function f(x) = sin(x) is 2π.
Your Answer Is 2π.
plz mark me as brainliest if this helped :)
We can use substitution.
We can substitute 2x + 3 for 'y' in the 2nd equation.
y = 3x + 5
2x + 3 = 3x + 5
Subtract 3 to both sides:
2x = 3x + 2
Subtract 3x to both sides:
-x = 2
Multiply -1 to both sides:
x = -2
Now we can plug this into any of the two equations to get our y-value:
y = 2x + 3
y = 2(-2) + 3
y = -4 + 3
y = -1
So our solution is (-2, -1)
Trial and error specifies that you should guess the value of m and see if you aimed too low too high then adjust your next guess based on that.
Suppose we don't already know what m is (even though it is completely obvious), let's pick m to be 6,
So we check, 
but 
which means m must be bigger.
So we pick m to be 8 and check, 
but 
which means m must be smaller.
Since only natural number between 6 and 8 is 7 we pick m to be 7 and check, 
and 
.
The answer is therefore 7.
Hope this helps :)
The answer is b= - 5/2
- 6 (b + 3)= - 8 + 5
- 6b - 18= - 3
- 6b= - 3 + 18
- 6b= 15
b= - 15/6
b= - 5/2
