Answer:
y = -7x - 2
Step-by-step explanation:
To write this into an equation, we need to use the y = mx + b formula.
y = mx + b
-30 = -7(4) + b <--- Substitute 4 as x, and -30 as y.
-30 = -28 + b
+ 28 +28 <--- Add 28 on both sides of the equation.
-2 = b
Final equation:
y = -7x - 2
<span>cos t(sect- cos t)
sec t = 1/cos t so
= cos t( 1/cos t - cos t)
= cos t / cos t - cos²t (distribute)
= 1 - cos²t
since sin²t + cos²t = 1, we have sin²t = 1 - cos²t
so
= sin² t
=right-hand side

The answer is A 16 degrees you just have to compare it to the other numbers and it is the smallest
Use simultaneous equations! ;)
