Law of cosine is :
c^2<span> = a^</span>2<span> + b^</span>2<span> − 2ab cos(theeta)
</span>so in case of right triangle , angle is 90 degree:
putting 90 degrees into formula:
c^2 = a^2 + b^2<span> − 2ab cos(90)
</span>As we know that:
cos90 = 0
c^2 = a^2 + b^2<span> − 2ab (0)
</span>c^2 = a^2 + b^2<span> - 0
</span>c^2 = a^2 + b^2 ( this is <span>pythagorean theorem ).
</span>So the above statement is True.
THE FLAT FEE OF $60 WOULD BE THE Y INTERCEPT BECAUSE THE $5 IS A RATE OF CHANGE DEPENDENT ON THE AMOUNT OF GIGABYTES THE PERSON USES.
Answer:
15x + 9 (We combing like terms. Ex. 16x and -x)
The point-slope form:
We have
Therefore
<h3>slope = -3 and the point (-2, 6)</h3>
------------
<h3>y + 2 = 2(x - 1)</h3>
2x - y = 4 <em>it's standard form Ax + By = C</em>
y = 2x - 4 <em>it's slope-intercept form y = mx + b</em>
y - x = 4 →<em> </em>x - y = -4 <em>t's standard form Ax + By = C</em>
