Answer:
Step-by-step explanation:
Since Θ is in fourth quadrant then cosΘ > 0, as is secΘ
Given
sinΘ = - 
, then
cosΘ = 
= 
= 
= 
Hence
secΘ = 
=
Answer:
54. slope: -1/5 y-intercept: -6
55. slope: -3x y-intercept: 12
Step-by-step explanation:
Integers are just whole numbers and their negative counterparts.
The set of integers is shown below.
{... -3, -2, -1, 0, 1, 2, 3, ...}
Decimals are not integers but rational numbers do include them.
So -8.4 is a rational number.
Answer:
x=1/2 y =1
Step-by-step explanation:
(-4x+2y)/2x5=0/2x5
10x+3y=8
(-2x+y)x5=0
10x+3y=8
-10x+5y=0
10x+3y=8
8y=8
y=1
x=1/2
