Step-by-step explanation:
y=x+6.......(1)
y=-3X-6....(2)
from eq (1), we get,
x=y-6....(3)
sub eq (3) in eq (2), we get
y= -3(y-6)-6
y= -3y+18-6
y+3y-12=0
4y=12
y=3
sub value of y in eq (3)
x=3-6
x=-3
This is a quadratic in the form of ax squared +bx +c
So
a = 3
b = -5
c = 2

Step-by-step explanation:
sin(x)=0.75------problem
1)you need to get x alone, so inverse
x=sin^-1 (0.75)
2)plug into calculator!
2 & 3
2+3=5
2x3=6
Hope this helps
