Answer:

<u>aₙ = aₙ₋₁ + 4</u>

Step-by-step explanation:

Finding the common difference (d) :

  • d = f(2) - f(1)
  • d = 7 - 3
  • d = 4

Hence, the recursive formula :

  • <u>aₙ = aₙ₋₁ + 4</u>

Which equations represent the line that is parallel to 2x-7y=9 and passes through the point
almond37 [142]

Answer:

e. 2x - 7y = 31.

Step-by-step explanation:

If you want a line parallel to the equation, the line must have the same slope.

2x - 7y = 9

-7y = -2x + 9

y = 2/7x - 9/7

You are looking for a line where the slope is 2/7.

a. Slope is 7/2.

b. Slope is -7/2.

c. Slope is 7/2.

d. Slope is...

y + 2 = 3/4x + 3

y = 3/4x + 1

Slope is 3/4.

e. Slope is -2/-7, which is 2/7. Just make sure to check whether it passes through (5, -3) by substituting those points into the equation.

2 * 5 - 7 * -3 = 31

10 --21 = 31

10 + 21 = 31

And there's your answer: e.

Find a formula for the nth term in this arithmetic sequence:
Sati [7]

The nth term of the arithmetic sequence is Tn = -7 + ( n - 1) 6

<h3>What is an arithmetic sequence?</h3>

An arithmetic sequence is defined as a sequence of numbers where the differences between every two consecutive terms is the same  through out the sequence.

The nth term of an arithmetic sequence is expressed as;

an = a + ( n - 1) d

Where;

  • a is the first term
  • n is the number of terms
  • d is the common difference

Substitute the values

an = -7 + ( n - 1) 6

Thus, the nth term of the arithmetic sequence is Tn = -7 + ( n - 1) 6

20 is what percent of 52
Maslowich
The process here is finding out the smallest number's % towards the largest number.

Divide 20 by 52:
20/52 = 0.38 (estimated) | This is the % in decimal form, which is 38%.

Conclusion: 20 is 38% of 52.

{---Further Elaboration for Future Reference---}

Finding the Smallest Number:

What number is 25% of 60?

Multiply 60 by the decimal form of 25%.
60 * 0.25 = 15 | 15 is 25% of 60.

Finding the Percentage. (Like what we already did.)

30 is what percent of 150?

Divide 30 by 150.
30/150 = 0.2 | 30 is 20% of 150.

Finding the Largest Number.

12 is 30% of what number?

Divide 12 by the decimal form of 30%.
12/0.3 = 40 | 12 is 30% of 40.

I hope this helps, have a great rest of your day! ^ ^
