-2 and 5 (just put in a graphing calculator and find the zeros)
You can set up an system of equations
x=2y+8
x-y=25
Substitute x in to the second equation
2y+8-y=25
y+8=25
y=17
Substitute the y back in to the first equation.
x=2(17)+8=42
Answer:
can you show a pic tell me in the comments
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Using the exact values
cos150° = - cos30° = - 
sin150° = sin30° = 
Given
z = 4(cos150° + isin150° ) , substitute values
= 4(-
+
i )
= - 2
+ 2i , that is
(- 2
, 2 ) → B
It’s B I did this question and got the same answer
