First do 6 divided by 10
then add 8.75 to that
Answer: Isolate the variable by dividing each side by factors that don't contain the variable. x=−4
Step
Answer:
c This is the direct variation
Step-by-step explanation:
The equation for direct variation is y= kx
Solving this for k
y/x =k
So y/x must be a constant
a. 9/3 =3
2/7 does not =3 so this is not a direct variation
b 1/2 = .5
-3/6 = -.5
This is not the same so this is not a direct variation
c. 27/9 =3
18/6 =3
9/3 =3
This is a direct variation with a constant of 3
d 5/-7 = -5/7
1/-3 = -1/3
This is not the same so this is not a direct variation
Answer:
a. They are equal and parallel.
Step-by-step explanation:
Since they both have the same magnitude, then they are equal.
Since they both move in opposite direction, then they are parallel.
