13) A cell phone plan cost $200 to start. Then there is a $50 charge each month. What is the total cost for x months? (Hint: Write the expression needing to find the total cost)
Answer:
50x + 200
Step-by-step explanation:
50 dollars each month (for x months) is 50x, and the initial cost is 200 (flat fee) which means that the expression is 50x+200
Answer:
50x+200
Step-by-step explanation:
Our constant term is the 200, because it's the upfront charge. Our coefficient is going to be 50, because 50 dollars are being charged each month.

What is an arrangement?An arrangement is a permutation of a set of objects in mathematics where the order of the things is important. An arrangement is specifically an orderly succession of unique elements drawn from a set.
Consider the set "A, B, C," for instance. This set can be arranged in six different ways: ABC, ACB, BAC, BCA, CAB, and CBA. The three components of the set are stated in a precise order in each of these configurations.
The number of ways that 7 students can be arranged in a line is 7! (7 factorial) which is equal to:
7! = 7 x 6 x 5 x 4 x 3 x 2 x 1 = 5,040
Therefore, there are 5,040 different ways that the first seven students in line can be ordered.

Examine this graph representing US unemployment rates. Which of these years might economists consider a trough? 1980 1982 1983 1985.
Graphs can represent a function, table and ordered pairs
The year that economists might consider a trough is 1982
How to determine the trough yearFrom the graph, we have the following parameters:
1980 = 7%1981 = 9%,1982 = 11%1983 = 8%1984 = 7%2985 = 7%In this case, the year that can be considered a trough is the year when the rate of unemployment is at highest (i.e. 11% in 1982)
Hence, the year that economists might consider a trough is 1982

Answer:
A: $250B: $600, earns more interestStep-by-step explanation:
The simple interest formula is ...
I = Prt . . . . . r is the interest rate, t is the number of years
Solving for P, we have ...
P = I/(rt)
Account A6 months is 1/2 year, so the principal is ...
P = $4.38/(0.035×1/2) = $250.2857...
Rounded to the nearest dollar, the principal invested is $250.
__
Account BUsing the same approach, for 18 months, t = 18/12 = 3/2 = 1.5.
P = $20.70/(0.023×1.5) = $600
The principal in Account B is $600.
__
First Month's Interest
Using the interest formula, the first month's interest in each account is ...
A: I = 250×0.035×1/12 = $0.73
B: I = 600×0.023×1/12 = $1.15
Account B earns more interest in the first month.

Answer:
A) x = 0, y = 14
Step-by-step explanation:
Line A: y = 6x + 14
Therefore, the slope of line A = 6
If Line B is perpendicular to Line A, then the product of their slopes is -1.
⇒ slope of Line B = [tex]-\dfrac16[/tex]
Given Line B passes through point (2, 13 2/3).
Use slope-point form of linear equation to find equation for Line B:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-13 \frac23=-\dfrac16(x-2)[/tex]
[tex]\implies y=-\dfrac16x+14[/tex]
Solution of system is the point where the lines intersect.
From inspection of the equations of the lines, the point of intersection is (0, 14)
write an exponential function in the form y=ab^x that goes through the points (0,14) and (6,896)
Answer:
y = 14 [tex](2)^{x}[/tex]
Step-by-step explanation:
Find a and b by substituting the points into the equation
using (0, 14 ) , then
14 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , then
14 = a × 1 ⇒ a = 14
y = 14 [tex]b^{x}[/tex]
using (6, 896 )
896 = 14 [tex]b^{6}[/tex] ( divide both sides by 14 )
64 = [tex]b^{6}[/tex] ( take the sixth root of both sides )
b = [tex]\sqrt[6]{64}[/tex] = 2
Then
y = 14 [tex](2)^{x}[/tex] ← is the exponential function

A piecewise function f(x) is defined by f(x) = { –X? + x + 2
x2 – 3x+2
for x>1
x>
Part A Graph the piecewise function () and determine the range (5 points)
Part B. Determine the asymptotes of f(x). Show all necessary calculations. (5 points)
Part C. Describe the end behavior of f(x). (5 points)
Answer:
A) see attached for a graph. Range: (-∞, 7]
B) asymptotes: x = 1, y = -2, y = -1
C) (x → -∞, y → -2), (x → ∞, y → -1)
Step-by-step explanation:
Part AA graphing calculator is useful for graphing the function. We note that the part for x > 1 can be simplified:
[tex]\dfrac{-x^2+x+2}{x^2-3x+2}=-\dfrac{(x-2)(x+1)}{(x-2)(x-1)}=-\dfrac{x+1}{x-1}\quad x\ne 2[/tex]
This has a vertical asymptote at x=1, and a hole at x=2.
The function for x ≤ 1 is an ordinary exponential function, shifted left 1 unit and down 2 units. Its maximum value of 3^-2 = 7 is found at x=1.
The graph is attached.
The range of the function is (-∞, 7].
__
Part BAs we mentioned in Part A, there is a vertical asymptote at x = 1. This is where the denominator (x-1) is zero.
The exponential function has a horizontal asymptote of y = -2; the rational function has a horizontal asymptote of y = (-x/x) = -1. The horizontal asymptote of the exponential would ordinarily be y=0, but this function has been translated down 2 units.
__
Part CThe end behavior is defined by the horizontal asymptotes:
for x → -∞, y → -2
for x → ∞, y → -1
