Answer:
4
Step-by-step explanation:
y=4x-4 original equation
y=4(2)-4 substitute x value
y= 8-4 simplify
y=4 solved
Answer:
sin (2A+2B) = 0
Step-by-step explanation:
Given that,
cosec A= -2 and sec B= -2, A and B lie in the same quadrant.
We need to find the value of sin (2A+2B).
And
To find the value of sin (2A+2B) as follows :
sin [2(-30)+2(120)] = sin (-60+240)
=sin (180)
= 0
So, the value of sin (2A+2B) is qual to 0.
Answer:
x= -5 y= -1
Step-by-step explanation:
hmmm let's find the distance between B and C first off.
hmmm if BC is that much, then AB + AC = 7, since AB + AC + BC = 12 which is the perimeter, Check the picture below.
