y1=m(x1)+b
Step-by-step explanation:
Answer:
-24/5
Step-by-step explanation:
The solution to the problem is as follows:
cscx < 0 means 1/sinx < 0, or sinx < 0.
sinx = -3/5 because you're dealing with a 3-4-5 triangle, and we established
sinx is negative.
sin2x = 2sinxcosx = 2*-3/5*4/5 = -24/25
cos(2x) = cos^2(x) - sin^2(x) = 16/25 - 9/25 = 5/25 = 1/5
tan2x = sin2x / cos2x = -24/5
Answer:
How long did she work for though?
Step-by-step explanation:
Answer:
I'm not sure.
Step-by-step explanation:
Answer:
27
Question:
Find 
so that 
is a solution to 
.
Step-by-step explanation:
So we are asked to replace 
with -14 and solve for in the equation:
.
with 
:
Add 42 on both sides:
Divide both sides by 2:
.
So the -coordinate that corresponding to is 
.
Verify that:
is a point satisfying .
Replace with 27 and with -14:
is true so our work must be right.
