A. vertical line; no
B. horizontal line; no
C. horizontal line; yes
Answer:
no it is not, A
Step-by-step explanation:
functions are things which u can draw vertical lines through and it never intersects(one x value leads to exactly one y value) at more than one point so A because x=7 is infinite y values for one x value.

A rectangular-shaped box has the following dimensions: 12 yards, 8 yards, and 18 yard. What is the surface area of the box?
Answer:
912 is the surface area
Surface area of the cuboid is the sum of the area of all the sides. The surface area of the box is 912 yards².
What is the surface area of the cuboid?The surface area of the cuboid is the sum of the area of all 6 sides of the cuboid.
The surface area of the cuboid
= 2[(Length x breadth)+(Length x height)+(height x breadth)]
As it is given to us that the box is rectangular, therefore, the actual shape of the box is cuboid. And for a cuboid, the surface area is given as,
The surface area of the cuboid
= 2[(Length x breadth)+(Length x height)+(height x breadth)]
Also, the length, breadth, and height of the cuboid is 12 yards, 8 yards, and 18 yards, therefore,
The surface area of the box = 2[(12 x 8)+(12 x 18)+(8 x 18)]
= 2[(96)+(216)+(144)]
= 912 yards²
hence, the surface area of the box is 912 yards².

Hello again davetriona12! I can help you.
We have 2.99, 3.19, 3.39, and 3.79
In order to solve this, we need to find out how much is being added every time. To do this, we will subtract 2.99 from 3.19 which gives us 0.20
So each time, 0.20 gets added.
Now that we have that information, we are ready to find the blanks.
For the first blank, we will subtract 2.99 - 0.20 which will give you 2.79
For the second blank, we will add 0.20 to 3.39 which will give you 3.59
Hope this helps you!

Elena plays the piano for 30 minutes each practice day.
The total number of minutes p that Elena practiced last week is a function of n, the number of practice days.
What is the domain for this function?
What is the range of this function?
Answer:
Step-by-step explanation:
f(n)=30n
domain all real numbers
range all real numbers
I think.
Domain is {0, 1, 2, 3, ...} and range is {0, 30, 60, 90, ...} for function p=30n.
What is a function?A relation is a function if it has only One y-value for each x-value.
The function that relates the total number of minutes practiced, p, to the number of practice days, n, is given by:
p = 30n
where 30 is the number of minutes Elena practices each day.
Since we cannot have negative practice days, the domain of the function is the set of non-negative integers:
Domain: {0, 1, 2, 3, ...}
The range of this function is the set of all possible values of p that can be obtained by plugging in values of n from the domain.
In this case, since the function only outputs non-negative values, the range is the set of non-negative integers:
Range: {0, 30, 60, 90, ...}
Hence, Domain is {0, 1, 2, 3, ...} and range is {0, 30, 60, 90, ...} for function p=30n.

At a cookout, Mrs. Crawford makes 8/9 pound of chicken, plus 1 pound for each guest. Is the relationship between the number of guests and pounds of chicken proportional? Explain.
Answer:
No, this rel. is not proportional because of the addition involved ("plus 1 lb for each guest").
A proportional rel. features mult. only.
Step-by-step explanation:
et x represents the number of guest and y represents the number of pounds of chicken made,
Given,
The number of pounds of chicken for each guest = 1,
So, the number of pounds for x guests = x,
Also, the number of pounds already made =
Thus, the total pounds of chicken,
Since, a relation is called proportional if the variables are directly proportional,
That is, the line obtained by the relation passes through the origin,
Since, if x = 0, y = 0,
∴ Line does not pass through the origin.
