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:

Step-by-step explanation:
<u><em>The correct question is: </em></u>
Darcy harvests 8 3/4 acres of corn every 5/6 of an hour. Darcy harvests corn at a constant rate. How many acres does she harvest per hour?
we know that
To find out the corn rate harvested per hour or the unit rate, divide the number of acres of corn harvested by the total time it takes
so

Convert mixed number to an improper fraction

substitute

Convert to mixed number
