The y-intercept is found when x is set to 0.
Set x to equal 0 for both equations:


Divide both sides by -2:

The y-intercept of this equation is 3, so the first line does not have the y-intercept of -2.
-


Divide both sides by 2:

The y-intercept of this equation is -1, so the second line does not have the y-intercept of -2.
Neither line has a y-intercept of -2.
Plan B is the answer I’m pretty sure
Answer:
57°
Step-by-step explanation:
Let's assume the measurement of the second angle is x.
so, following the problem
(2x + 9) + x = 180
2x + x = 3x
=> 3x + 9 = 180
=> 3x = 180 - 9
3x = 171
x = 171/3
x = 57°
57° is the smallest angle
Answer:
r = - 
Step-by-step explanation:
The n th term of a GP is
= a₁ 
where a₁ is the first term and r the common ratio
Here a₁ = 18 and a₆ = -
, then
18
= -
( divide both sides by 18 )
= -
( take the fifth root of both sides )
r =
= -
