Answer:
Domain : All real numbers
Range: x<0
Step-by-step explanation:
Answer: A union B = B
The first one should’ve said A intersects B = A because the entirety of A exists in B
here the equation of path is -2x-7=y
let us find slope of this line by using y=mx+b
so slope m=-2
now new path is perpendicular to this path.
product of slopes of perpendiculars is -1
so slope of new path is 1/2
now it passes through (-2,-3) with slope 1/2
using y=mx+b to get value of b
-3=1/2(-2) +b
b=-2
plugging m=-1/2 and b=-2 in y=mx + b to get the final equation as
y=(-1/2) x -2 is the equation of new path
Answer:
w=7
Step-by-step explanation:
3w+4w=49
7w=49
w=49/7
w=7
