Answer:
y = 4x + 3
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 )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 1, - 1) and (x₂, y₂ ) = (0, 3)
m = 
= 
= 4
The line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = 4x + 3 ← equation of line

YA NA NA YA
Step-by-step explanation:
Cuz im smart
72 degrees
Since it's a regular polygon with 5 sides, you divide 360 by 5. You'd end up with 72. Hope this helps
Recall the double angle identity,
sin(2x) = 2 sin(x) cos(x)
Then we can write
sin(9x) cos(9x) = 1/2 sin(2 • 9x) = 1/2 sin(18x)
Then
∫ sin(9x) cos(9x) dx
= 1/2 ∫ sin(18x) dx
= -1/2 • 1/18 cos(18x) + C
= -1/36 cos(18x) + C
though you could continue with another double angle identity,
cos(2x) = cos²(x) - sin²(x)
to rewrite the antiderivative as
= -1/36 (cos²(9x) - sin²(9x)) + C
= 1/36 (sin²(9x) - cos²(9x)) + C
We can write multiple equations that have the same solution.
Two of these equations could be for example:
Equation 1:
10x = 12
Equation 2:
2x-1 = 1.4
Note: when clearing x in both equations we have:
x = 1.2
Answer:
10x = 12
2x-1 = 1.4
