4x^2+9x-(x^2-6x+9)+11
4x^2+9x-x^2+6x-9+11
3x^2+15x+2
X equals to 518/3 which equals to 172.6
Sec^2 x - 1 = tan^2x
Proof:
Sec^2x = 1+ tan^2x
1/cos^2x = 1 + sin^2x/cos^2x
<span>1/cos^2x - sin^2x/cos^2x = 1
</span>Using common denominator:
(1-sin^2x)/cos^2x = 1
sin^2x + cos^2 x = 1
cos^2 x = 1 - sin^2x
Substituting :
cos^2x/<span>cos^2x = 1
</span>1 = 1
Left hand side = right hand side
Answer:
B
Step-by-step explanation:
To find the answer, we can use the point-slope form:

Where (x₁, y₁) is a point and m is our slope.
Let's let our point (4, 1/3) be (x₁, y₁) respectively.
We also know that our slope is 3/4. So, substitute 3/4 for m.
This yields:

The choice that represents this is B.
So, our correct answer is B.
And we're done!
