Answer:

  • an = 160·0.85^(n-1)
  • $51.29

Step-by-step explanation:

In the given formula, a1 refers to the first term of the sequence (160), and r refers to the common ratio (136/160 = 0.85). Putting these values into the formula gives ...

a) Explicit formula: an = 160·0.85^(n-1)

__

b) The 8th term is found by putting n=8 into the formula and doing the arithmetic:

  a8 = 160·0.85^(8-1) ≈ 51.29

Answer:

an = 160[0.85^(n-1)]

$51.29

Step-by-step explanation:

a = 160

ar = 136

r = 136/160 = 0.85

an = 160[0.85^(n-1)]

a8 = 160[0.85^(8-1)]

= 51.29233413

Which phrase represents the algebraic expression 3p+6/7p-9
omeli [17]

Answer:

The answer is the sum of three times a number and six, divided by the difference of seven times the number and nine

Step-by-step explanation:

3p = three x a number

7p = seven x a number

3p+6 = sum of three x a number plus six

7p-9 = difference of seven x the number minus nine

(3p+6)/(7p-9) = sum of three times x number plus six, divided by the difference of seven x the number - nine

Solve<br><br> y=34x<br> y=-54x+52
jeyben [28]

Answer:

x= 13/22

Step-by-step explanation:

you can substitute y= 34 x on the second equation

34x = -54x +52  add 54x to both sides

34x +54x  = -54x +54x +52

88x = 52  divide both side by 4

22x = 13  divide both sides by 22

x= 13/22
