LiRa [457]3 years ago

Start by multiplying b to both sides of the equation to get rid of the fraction. Now you have: Ub = ak.

To isolate a, divide both sides of the equation by k. \frac{Ub}{k} = a is the final answer.

Find the 78th term of the arithmetic sequence<br> -12,-13,-14,
creativ13 [48]

Answer:

  -89

Step-by-step explanation:

The first term of the sequence is a1 = -12.

The common difference between terms is ...

  d = -13 -(-12) = -1

The generic term is given by ...

  an = a1 +d(n -1)

Then the 78th term is ...

  a78 = -12 +(-1)(78 -1) = -12 -77

  a78 = -89

Family Video charges $10 for
Irina18 [472]

Answer:

4 movies, $20

Step-by-step explanation:

Given data

Family Video

charges $10 for a monthly membership and

$2.50 per movie

let the number of movies be x

and the charge for x movies be y

y= 10+2.5x----------1

Babe's  Movies

charges a $12

membership and $2 per

movie.

let the number of movies be x

and the charge for x movies be y

y= 12+2x----------2

equate 1 and 2

10+2.5x= 12+2x

collect like terms

12-10= 2.5x-2x

2= 0.5x

x= 2/0.5

x= 4 movies

put x= 4 in equation 1 or 2

y= 12+2x----------2

y= 12+2*4

y= 12+8

y= $20

No it is not equal. 3.55 divided by 5=0.71.    0.3 divided by 5+ 0.05 divided by 5 equals to 0.07.

Pls help oooooooooooo
Digiron [165]

Answer:

110

Step-by-step explanation:

Suppose lines EH and BD are parallel:

Angle <GFE and angle <ABC are supplementary so their sum is equal to 180

2x + 10 + x  + 20 = 180 add like terms

3x + 30 = 180 subtract 30 from both sides

3x = 150 divide both sides by 3

x = 50

We are asked the value of <ACD

<ABD and <ACD are also supplementary so we can find the value od <ACD:

x + 20 + <ACD = 180 we know x = 50 so we can replace x with that

50 + 20 + <ACD = 180

70 + <ACD = 180 subtract 79 from both sides

<ACD = 110

Given the recursive formula below, what are the first 4 terms of the sequence?
ANEK [815]

Answer:

D)

17,15,13,11

Step-by-step explanation:

From the formula

f(n) = f(n - 1) - 2 \\ f1 = 17 \\

  • we can deduce the next three terms as follows:
  • f(2) = f(2 - 1) - 2 \\ f(2)= f(1) - 2 \\ f(2) =  17 - 2 \\ f(2) = 15\\
  • f(3) = f(3 - 1) - 2 \\ f(3)= f(2) - 2 \\ f(3) =  15 - 2 \\ f(3) = 13\\
  • f(4) = f(4 - 1) - 2 \\ f(4)= f(3) - 2 \\ f(4) =  13 - 2 \\ f(4) = 11\\
  • Hence the sequence is; 17, 15, 13, 11,...
