Answer:
a) linear
b) nonlinear
c) nonlinear
d) nonlinear
Step-by-step explanation:
For a linear equation the highest degree is 1. If the degree is more than 1, then it is a non-linear equation.
a) 7x=y-4 is a linear equation because the highest degree is one
b)

is not a linear equation because when we multiply through by x, we get

The degree is 2
c) 6xy +3x=2 is non linear because the degree is 2.
d) x=2y³ +y is non-linear be because the degree is 3.
Answer:
9 1/7
Take 5 4/7 + 3 13/21 and get 9 1/7
Answer:
9 days
Step-by-step explanation:
100 + 50= 150
100 scouts= 12 days
×2 ÷2
200 scouts= 6 days
Midpoint of 100 scouts and 200 scouts= 150
Midpoint of 12 days and 6 days= 9 days
