Answer:
B. 30
D. 90
Step-by-step explanation:
The cost for an upcoming field trip is $30 per student. The cost of the field trip C, in dollars, is a function of the number of students x. Select all the possible outputs for the function defined by c(x) = 30x. A. 20 B. 30 C. 50 D. 90 E. 100
Given function:
C(x) = 30x
Where,
x = number of students
A. 20
C(x) = 30x
20 = 30x
x = 20/30
= 0.67
x = 0.67 student
B. 30
C(x) = 30x
30 = 30x
x = 30/30
x = 1 student
C. 50
C(x) = 30x
50 = 30x
x = 50/30
x = 1.67 students
D. 90
C(x) = 30x
90 = 30x
x = 90/30
x = 3 students
E. 100
C(x) = 30x
100 = 30x
x = 100/30
= 3.33
x = 3.33 students
Number of students, x should be an whole number
The possible for the function are
B. 30
D. 90

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of 2 pencils be = A
Now , the equation will be
The cost of 6 pencils is = 36 cents
So ,
The cost of one pencil is = cost of 6 pencils / 6
The cost of one pencil is = 36 / 6
The cost of one pencil is = 6 cents
And , the cost of 2 pencils is calculated by the equation
The cost of two pencils is A = cost of one pencil x 2
The cost of two pencils is A = 6 x 2
The cost of two pencils is A = 12 cents
Therefore , the value of A is 12 cents
Hence , The cost of 2 pencils is 12 cents

y=4x-2
Step-by-step explanation:
Stock prices for a certain company start at $12 per share an increase at a rate of
$2 per month. Write an equation of the function of the value of the stock price v,
as a function of the number of month that have passed, m.
Step-by-step explanation:
V = $12
M = The number of months
So, function = v + $2m
Lets take an Example = for example the stock price now is $20
V + $2m = $20
V = $12
So, 12 + $2m = 20
$2m = 20 - 12
$2m = 8
m = 8/2
m = 4
So this used we can easily find the number of months
Now let's try with the stock price only
The total now is $24
And 6 months passed
v + $2m = $24
v + $2(6) = $24
v + $12 = $24
v = $24 - $12
v = $12
So we got the same stock price
We found with this function the stock price as well as the number of months

Answer:
(6, 12)
Step-by-step explanation:
The center of the circle is the midpoint of the diameter, the average of the end point coordinates:
((3, 8) +(9, 16))/2 = (3+9, 8+16)/2 = (12, 24)/2 = (6, 12)
The center of the circle is (6, 12).

Step-by-step explanation:
Two
If one side of a square is 50 miles, all sides are.
a^2 + b^2 = c^2
You are looking for c. a and b both equal 50
50^2 + 50^2 = c^2
c^2 = 2500 + 2500
c^2 = 5000
√c^2 = √5000
c = 70.7 miles
One
Again you are using a^2 + b^2 = c^2
c = 169
Perimeter of square 2 = 48
a = ?
a is square 3.b is square 2c is square 14s = 48
s = b = 48/4
s = b = 12
area_2 = s^2
Area_2 =12^2
Area_2 = 144
Area_ 1^2 - Area_2 ^2 = Area_3^2
169 - 144 = Area_3^2
side_3 = sqrt(25)
area= 25

45 =p x 60
NEED HELP ASAP
Answer:
p = 3/4 or 0.75
Step-by-step explanation:
your equation: 60p = 45
divide both sides by 60: p = 45/60
simply the fraction by dividing the numerator and denominator by 15: p = 3/4
your answer: 3/4 or 0.75
Answer: p = 75%
Step-by-step explanation:
p = 45/60 then divide that by 15/15
so 45 divided by 15 is 3
and 60 divided by 15 is 4
this equals too 3/4 = 0.75
0.75 = 75%
