i.
j.
<u>Neither:</u>
f.
h.
<u>Linear:</u>
b.
d.
g.
Step-by-step explanation:
Linear equations are generally expressed in the form y = mx + b - the highest exponent of x is one.
Quadratics are expressed as y = ax^2 + bx + c - the highest exponent of x is two.
Any equation with an exponent of x higher than two is neither linear nor quadratic, but instead cubic or higher. Therefore we can simply sort these equations by the highest exponent of x present after simplifying.
Unit price = total price / size
unit price for 25 ounce can :
$4.80 / 25 ounces = $0.192 per ounce
We can use ratios to find the answer to this.
Set up the ratio.
3/4 / 18/7 = x / 1
Multiply both sides by 1
3/4 / 18/7 = x
Inverse 18/7 to 7/18 so we can multiply.
3/4 * 7/18 = x
Multiply.
21/72 = x
Simplify7/24 = x
Therefore, 7/24 cups of oats is used per pound.
