Find an equation for the nth term of the arithmetic sequence.
a19 = -58, a21 = -164
a. an = 896 - 53(n - 2)
b. an = 896 - 53(n - 1)
c. an = 896 + 53(n + 1)
d. an = 896 - 53(n + 1)
Answers
Answer:
The common difference would be calculated as:
(a21-a19)/2
(-164--(-58 ))/2 (Replacing the values )
(-164 +58)/2 (Changing signs)
(-106)/2(Subtracting)
-53
Then we are going to replace the common difference(d) in the sequence formal with the 21st term . It is done for finding the first term of the sequence.
a21=a0+d*(n-1)
-164=a0+-53*(21-1) (Replacing the values)
-164=a1-53(20) (Subtracting)
-164=a1-1060 (Multiplying )
-164+1060=a1 (Adding 1060 on both sides of the equation)
896=a1
The answer would be : an= 896-53*(n-1), which is the option B.

i used a graphing calculator,
solve for m. show you work. 6 (m - 8) = 30
Answers
Answer:
m=13
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6(m−8)=30
(6)(m)+(6)(−8)=30(Distribute)
6m+−48=30
6m−48=30
Step 2: Add 48 to both sides.
6m−48+48=30+48
6m=78
Step 3: Divide both sides by 6.
6m/6=78/6
m=13

Okay so I’m doing graph questions, so what’s “g(x) = x + 1” and what are the blanks?
Answers
Answer:
g(0) = 1, g(1) = 2, g(2) = 3, g(3) = 4, g(4) = 5
Step-by-step explanation:
g(x) is a function meant to modify the variable x.
Basically you take the x value in the table that you want to modify and you plug it into the g(x) function.
If you want 0, you do g(0) = (0) + 1 = 1.
Or if you want 3, you do g(3) = (3) + 1 = 4

Gertrude paid $32.50 last month for 175 minutes of phone calls.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
We are given that cellphone plan has a fixed cost of $15, this means that regarding if we use it or not, you'll pay at least $15.
Also, added to those fixed costs, we pay $0.10 per minute for phone calls.
Acording to the information, the bill for last month was $32.50, first step is to remove the fixed charges to know how much was spent on phone calls:
$32.50-$15= $17.5
Now, cross multiplication so that can calculate how many minutes she talked to spend $17.5:
$0.10____1min
$17.50___xmin
x = 175
Hence She talked 175 minutes over the phone.

Two objects are moving along separate linear paths where each path is described by position, d, and time, t. The variable d is measured in meters, and the variable t is measured in seconds. The equation describing the graph of the position of the first object with respect to time is d = 2.5t + 2.2. The graph of the position of the second object is a parallel line passing through (t = 0, d = 1). What is the equation of the second graph?

Answers
Answer:
A) d = 2.5t+1
The equation of the second graph d = 2.5t+1
Step-by-step explanation:
Explanation:-
Given equation describing the graph of the position of the first object with respect to time is d = 2.5t + 2.2.
Given that the point ( t=0,d=1)
The parallel line to the given line
d = 2.5t +k ...(i)
The equation (i) passes through the point ( t=0,d=1)
1 = 2.5(0) +k
k =1
The equation of the parallel line
d = 2.5t + 1

Robin has $450 to spend on home repairs. The repairman charges $65 for the initial visit and $37.50 per hour or part of an hour. How many hours of work can Robin afford?
Answers
Answer:
6 hours
Step-by-step explanation:
First set up the equation. Seeing the word "per", we know that this will be the variable. The repairman charges an initial fee of 37.50, so we add that fee to the total cost of every hour. To find how much Robin can spend, you set it equal to 450
65x + 37.50 = 450
Now subtract 37.50 from both sides because neither number has a variable, so you can subtract them to simplify the equation
65x = 412.5
To isolate x and find what it's equal to, divide both sides by 65 to get rid of the coefficient.
x = 6.34.
However the answer should be 6 because robin cannot afford a full or part of a 7th hour
Dave uses 5 gallons of gas to drive 140 miles on the highway. If he travels at the same rate, how many miles can he drive on 7 gallons of gas?
Answers
Answer:
168 miles
Step-by-step explanation:
If he uses 5 gallons to drive 140 miles, that means that he can drive 24 miles for every gallon (140/5=24)
7 times 24 is 168 so he can drive 168 miles on 7 gallons of gas
