Answer:
y = -x + 5
Step-by-step explanation:
X, Y, and B is given using fomula y = m(x) + b
Subsitute those variables.
0 = -(5) + b
Solve for m.
0 = -5 + b
+5 +5
b = 5.
Then plug in the b and take out the x and y.
y = -x + 5
Arcsecant or arcsec or sec⁻¹ is an inverse trigonometric function. And many calculators don't have a key for them because they can be calculated with basic trigonometric functions like so:
sec⁻¹(x)=cos⁻¹(1/x).
So the correct answer is the fourth one: y=cos⁻¹(1/x).
Answer:
see below
Step-by-step explanation:
m²+8m=0
Factor out an m
m(m+8) =0
Using the zero product property
m=0 m+8 =0
m =0 m=-8
