Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 4 and d = a₂ - a₁ = 1 - (- 4) = 1 + 4 = 5 , thus
[tex]a_{n}[/tex] = - 4 + 5(n - 1) = - 4 + 5n - 5 = 5n - 9
Then
a(50) = 5(50) - 9 = 250 - 9 = 241

Graph the linear function d(x)=−1/2x−3.
Answer:
Step-by-step explanation:
The required graph of the given function d(x)=−1/2x−3 has been shown.
Given that, to plot the graph of the linear function, d(x)=−1/2x−3.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
The graph of the liner function d(x)=−1/2x−3 can be plot by putting the values of the x in the equation which gives the value of y by calculating such an ordered pair we can plot the curve of the liner equation on the graph. i.e.
At x = 0
d(0) = -1/2 * (0) - 3
d(0) = -3
So, the ordered pair will be (0, -3).
Now, put x = 2
d(2) = -1/2 * 2 - 3
d(2) = -1 - 3
d(2) = - 4
So the ordered pair will be (2, -4)
joining these two points will show the graph of the given equation d(x)=−1/2x−3.
Thus, the required graph of the given function d(x)=−1/2x−3 has been shown.

Step-by-step explanation:
Answer:
A
Step-by-step explanation:
there are 2 ways to solve this...
1st, y=60 by the vertical angles theorem
2nd, x=120 by the linear pair postulate (x + 60 = 180)
next, y=60 because y + 120 = 180

Answer: 25%
The percentage change between 64 and 80 is a 25% increase.
Step-by-step explanation:
Answer:
Percent of increase - 80 - 64 = 16
% increase = Increase ÷ Original Number × 100.
= 16 ÷ 64 × 100
= 25 ℅

Chris's age is 17 more than one-fourth of Brian's age. How old is Chris if Brian is 27?
Answer:
23.75
Step-by-step explanation:
Given that:
Brian's age = 27
Age of Chris is 17 more than one - fourth of Brian's age.
To find:
Age of Chris = ?
Solution:
Let age of Chris = [tex]x[/tex]
One - fourth of Brian's age = [tex]\frac{27}{4}[/tex]
17 more than One - fourth of Brian's age = [tex]\frac{27}{4}[/tex] + 17
Therefore, we can write the equation as per question statement:
[tex]x = \frac{27}{4} + 17\\\Rightarrow x = 6.75+17\\\Rightarrow \bold{x = 23.75}[/tex]
Therefore, Chris is 23.75 years old if Brian is 27.

A company offers two monthly plans. Plan A costs $ 25 plus an additional $0.10 for each minute of calls. Plan B costs $18 plus an additional $0.15 for each minute of calls.
Answer:
The indifference point is 140 minutes.
Step-by-step explanation:
Giving the following information:
Plan A costs $ 25 plus an additional $0.10 for each minute of calls.
Plan B costs $18 plus an additional $0.15 for each minute of calls.
First, we need to establish the total cost formula for each plan:
Plan A= 25 + 0.1*x
Plan B= 18 + 0.15*x
x= number of minutes
Now, to calculate the indifference point, we equal both formulas and isolate x:
25 + 0.1x = 18 + 0.15x
7 = 0.05x
140=x
The indifference point is 140 minutes.
Prove:
Plan A= 25 + 0.1*140= $39
Plan B= 18 + 0.15*140= $39

A new backpack costs $45.00 plus 7.4% for sales tax. Find the amount of tax you would have to pat for the backpack.
Answer:
$48.33
Step-by-step explanation:
1. Find the amount of the sales tax by multiplying the tax percentage by the sales price.
$45 × 7.4% = $3.33
2. Add the amount of the sales tax back to the sales price.
$45.00+$3.33 = $48.33
