X=4 btw is there any answer choices?
A)
The slope-intercept form:
m - slope
b - y-intercept
The formula of a slope:
We have the points (2, 5.1) and (-1, -0.5). Substitute:
Therefore we have:
Put the coordinates of the point (-1, -0.5) ot the equation:
<em>multiply both sides by 2</em>
<em>add to both sides</em>
<em>divide both sides by 2</em>
Answer:
-------------------------------------------------------------------------
B)
We have the points (-2, 3) and (3, -4).
Calculate the slope:
Therefore we have:
Put the coordinates of the point (-2, 3) to the equation of a line:
<em>subtract from both sides</em>

Answer:
C. 18.40
Step-by-step explanation:
480÷30=16
16+15%=18.4
Answer:
Exact Form: 5/2
Decimal Form: 2.5
Mixed Number Form: 2 1/2
Step-by-step explanation:
For all <em>x</em>,
sin²(<em>x</em>) + cos²(<em>x</em>) = 1
so we have
(1 - cos²<em>A</em>) csc²<em>A</em> = sin²<em>A</em> csc²<em>A</em>
and since csc(<em>x</em>) = 1 / sin(<em>x</em>), so the expression reduces to 1.
