Answer:
(-1,6)
Step-by-step explanation:
{x+1=y}
{2x-y=0}
X+1=y
X=y-1
{2(y-1)-y=0}
{2y-2-y=0
{y-2=0}
{y=2}
Since y=2, and there’s only one ordered pair with y=2, the answer is B
Answer:
21
Step-by-step explanation:
11(-2)=-22
-22+3=-19
-18(-2)=36
-19+36+4
17+4=21
Use double angle formula
tan2x = 2tanx/ (1- tan^2x) = 2 * 7/11 ( 1 - (7/11)^2) = 77/36
