Answer:
Step-by-step explanation:
Write the equations in the form y = mx + b
If the equation contains exponents then it is non-linear, if not then it is linear.
2xy = 3
This graph forms a curve so it is non-linear
y = 1x³ + 5
This equation is non-linear because it contains an exponent
y = x/3
y = 1/3x + 0
This equation is linear ( no exponent(s) )
2y = 1/2x
y = 1/4x + 0
This equation is linear ( no exponent(s) )
Answer:
40 nickles
Step-by-step explanation:
Here is the correct question: Earl went to the store and realize he had 7 more Nickles in his pocket then he thought he had; If all the change in earl’s pocket is nickles, he had $2.35 in his pocket, how many more nickles did he think were in his pocket ?
Given: All Nickles in the Earl´s pocket is $2.35.
Remember, 1 Nickles = $.05
∴ Converting the dollar to nickels
$2.35=
Earl had total 47 nickels in his pocket.
∴ Earl earlier had nickles =
∵ we know Earl had realized that he had 7 more nickles in his pocket, which means he already had 40 nickles to make $2.35.
