Answer:
sin(4π/21)
Step-by-step explanation:
Step 1: Rearrange expression
sin(π/3)cos(π/7) - cos(π/3)sin(π/7)
Step 2: Use sin(A ± B)
sin(π/3 - π/7)
Step 3: Evaluate
sin(4π/21)
And we have our answer!
5y+4x
5(10) + 4(-5)
50 - 20
30
we have

we know that
If the point is an equation solution, it must satisfy the equation.
<u>case a</u>) 
Substitute the values of x and y in the equation


-------> the point is not solution of the equation
<u>case b</u>) 
Substitute the values of x and y in the equation


-------> the point is solution of the equation
<u>case c</u>) 
Substitute the values of x and y in the equation


-------> the point is not solution of the equation
<u>case d</u>) 
Substitute the values of x and y in the equation

-------> the point is not solution of the equation
therefore
<u>the answer is</u>
The point
is solution of the equation
Good question I’m having trouble with this but I hope someone understands this
Answer:
y + 2 =
(x - 10)
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y =
x - 4 ← is in slope- intercept form
with slope m = 
Parallel lines have equal slopes
The equation of a line in point- slope form is
y - b = m(x - a)
Here (a, b ) = (10, - 2 ) , then
y - (- 2) =
(x - 10) , that is
y + 2 =
(x - 10) ← in point- slope form
