Answer: Option b

x^4= y

Step-by-step explanation:

Linear equations have the following form:

a_1x^n + a_2y^m + a_3w^s + a_4v^h = b

Where the exponents n, m, s and h are always 0 or 1

To know which equations are nonlinear, identify among the options given, those that have exponents other than 1 or 0

Note that in option b) the exponent of the variable x is n = 4 therefore the equation is nonlinear

Finally the answer is the option b

Drinking 8 fluid ounces of milk provides 270.0 milligrams of calcium. How many fluid ounces of milk provide 72.5 milligrams of c
Margarita [4]
Set up a proportion:

\frac{8}{270} = \frac{x}{72.5}

The numerator represents fluid ounces of milk, and the denominator represents milligrams of calcium.

Simplify the first fraction to make multiplication easier:

\frac{8}{270} \div  \frac{2}{2} =  \frac{4}{135}
\frac{4}{135} = \frac{x}{72.5}

Cross multiply the fractions:

72.5 * 4 = 290
135x = 290

Divide both sides by 135 to get x by itself:

290 \div 135 = 2.1
x = 2.1


2.1 fluid ounces of milk provide 72.5 milligrams of calcium.
