Answer:
The regular size is more economical.
Step-by-step explanation:
Consider the provided information.
A regular tube of toothpaste costs $2.50 for 3.2 ounces.
Find out the unit rate as shown below:
Therefore, the cost of one ounce is $0.78.
A travel size tube costs $1.00 for 1.2 ounces.
Find out the unit rate as shown below:
Therefore, the cost of one ounce is $0.833.
From the above calculation we can observe that regular tube toothpaste price is better buy.
Now find the percent as shown:
Firs find the difference
$0.83-$0.78 = $0.05
Therefore,
Hence, regular tube is 6.41% less costly as compare to travel size.
Answer:
nonlinear
Step-by-step explanation:
The degree of x in the equation is not 0 or 1, so the function is nonlinear.
_____
<em>Additional comment</em>
Your function graphs as a parabola, not a straight line. A function is only linear if its graph is a straight (non-vertical) line.
Answer:
y = -x +3
Step-by-step explanation:
Think about the Y= mx + b
m = -1 so it's -x
b = 3, so it's +3
y intercept goes after the slope:
Y= Mx + B
Y = -x + 3

There are three possible results when a plan intersects with a three-dimensional figure and these are:
a point
a line
a plane
The first step in describing the result is to determine first how the plane and the figure intersects.
