Answer:
<em>− 2sin(b) / cos(2b)</em>
Step-by-step explanation:
DIFFERENTIATE W.R.T. B is a different method entirely
We simply add together the numerators and set with 2cos
then keep this number and add to sinb and square it.
then repeat initial 2 + cosb ^2 but instead of multiplying its add.
Then set the whole division to -sin (2b) squared then +1
<em> − 2cos(b)(3(sin(b))^2+(cos(b))^2) / −(sin(2b)) ^2 +1 </em>
Answer:
c. (2, -18)
Step-by-step explanation:
y = -5x - 8
y = 3x - 24
3x - 24 = -5x - 8
8x = 16
x = 2
y = 3x - 24
y = 3(2) - 24
y = 6 - 24
y = -18
Answer: c. (2, -18)
Answer:
y= -2x-3
Step-by-step explanation:
Using the slope intercept form we have to first find the gradient of the line.
m=(y₂-y₁)/(x₂-x₁)
y₁=5
y₂=-9
x₁=-4
x₂=3
Therefore, m= (-9-5)/(3--4)
=-2
Therefore if we pick any point on the line, say, (-4,5) we obtain the same slope.
(y-5)/(x--4)=-2
(y-5)/(x+4)=-2
y-5=-2(x+4)
y-5=-2x-8
y= -2x-3
Thus the equation of the line in the slope intercept form is: y= -2x-3
