Which expression represent the nth number in this sequence?
Answers
Answer:
a(n) = 5 + 13(n - 1)
Step-by-step explanation:
Note that each new number is obtained by adding 13 to the previous number. The common difference is 13 and the first number is 5. The general formula for an arithmetic sequence is
a(n) = a(1) + d(n - 1), where d is the common difference.
Here,
a(n) = 5 + 13(n - 1)

Answers
Answer:
y=1/3x-4
Step-by-step explanation:
The equation for slope-intercept form is y=mx+b.
m=slope
b=y-intercept
When you graph with slope intercept form, you start with whatever number that is the y-intercept. For this equation, you started at -4, so -4 is the y-intercept.
The equation now is y=mx-4. Now, find the slope.
The easiest way to figure out slope is to find the next point on the line and see how far it is from the y-intercept. The point closest (going right) is (3,-3). The slope is rise over run, or y/x. The rise, y, from the next point, is 1. The run, x, is 3. So, the slope is 1/3.
The equation in slope-intercept form is y=1/3x-4.

Jahan earns $2,456.75 every month. He also earns an extra $4.75 every time he sells a new gym membership. Last month, Jahan sold 32 new gym memberships. How much money did Krego earn last month?
Answers
Answer:
$2608.75
Step-by-step explanation:
given that Jane earn $2,456.75 every month
and earns $4.75 every time he sells a new gym membership
given the total number of membership is 32
let the total earnings be y
the number of membership be x
the model for her earning is
y= 2,456.75 +4.75x
substituting x=32 we have
y= 2,456.75 +4.75(32)
y=2,456.75 +152
y=2608.75
therefore she earned $2608.75

in 6 hours?
Answers
Answer: 52.5
Step-by-step explanation:
Divide 35 by 4
Multiply the number you get by 6
Answer:
Liam reads 52.5 pages in 6 hours
Step-by-step explanation:
to solve this problem you need to start with finding how many pages he reads in 1 hour.
to do this, divide 35 by 4.
35/4 = 8.75
the unit rate is 8.75 pages per hour.
now just multiply the unit rate by the amount of hours.
8.75 * 6 = 52.5
