Paralell has same slope
slope of ax+by=c is -a/b
so a paralalell line to ax+by=c is ax+by=z where a=a and b=b and z is a constant
so
paralalel to 3x-2y=-6 is 3x-2y=?
find ?
given point (4,2)
sub
3(4)-2(2)=12-4=8
equation is 3x-2y=8
solving for slope itnercept or y
minus 3x both sides
-2y=-3x+8
divide by -2
y=3/2x-4
B is answer
To solve this problem you must apply the proccedure shown below:
1. You have that :
-The <span>estimate from the moving is $675 for 6 hours of packing and 5 hours of moving.
- </span>The cost will decrease to $425 for 4 hours of packing and 3 hours of moving.<span>
x: rate for packing.
y: rate for moving.
6x+5y=675
4x+3y=425
2. When you solve the system of equations shown above, you obtain:
x=50
y=75
Therefore, the answer is: $50 (Rate for packing) and $75 (Rate for moving).

I think it is B -2 < x < 2
Answer:
100 degrees
Step-by-step explanation:
Since triangle ABC is similar to triangle DEF, their angles are basically the same.
All angles of a triangle have to add up to 180.
We are already given two angles: 30 and 50
Add them together: 30 + 50 = 80
Now we subtract the number from 180
180 - 80 = 100
The remaining angle has to be 100 degrees
