Answer:

( 2×8) - [ ( 5 + 15 ) ÷ 5] = 32

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Given equation = 2x18-5+15/5=32

First we multiply first two letters,

then ( 2 × 18) = 36

Now, we add 5 and 15 then divide it by 5,

So, ( 5 + 15 ) ÷ 5 = 20 ÷ 5 = 4

Now we subtract 4 from 36,

Then 36 - 4 = 32

Hence the correct parentheses = ( 2×8) - [ ( 5 + 15 ) ÷ 5] = 32

for a two week period, john and amanda had the following transactions occur to their cheking account: a deposit of $1,644.50;che

QveST [7]

a deposit of $1,644.50;checks written for $190, $45, and $7.50; and debit card transactions for $30, $5.59, $7.20, and $21.30.

amount deposited = 1644.50

debit card transactions for $30, $5.59, $7.20, and $21.30.

We add all the debit card transactions

30 + 5.59 + 7.20 + 21.30 =64.09

checks written for $190, $45, and $7.50

Add all the check written amounts

190 + 45 + 7.50=242.5

To find ending balance , we subtract the debit card transactions and check written from the deposit amount

1644.50 - 64.09 - 242.5 = 1337.91

$1,337.91 is the ending balance for this time frame

Topic: Finite Geometric Sums <br> what is the value of ..

Juli2301 [7.4K]

For i=1 ===> Sum=4

for i=2===> Sum=2

for I=3===> Sum=1

Hence the answer is 7

Or you could have use the Sum formula of a GP:

Sum = a(1-r)^n/(1-r), with a=1, r=1/2 & n=3

Let f(x) = 6x2 + 5 and g(x) = 3x - 5. Find f(g(0)).

professor190 [17]

First you do g(0):
g(0) = 3(0) -5
g(0) = -5
then you do f(-5):
f(-5) = 6(-5)2 +5

(4y^2-3y+2)+(5y+12y-4)-(13y^2-6y+20)

Andrews [41]

Answer:

-(9 y^2 - 20 y + 22) or if you need y = 10/9 + (7 i sqrt(2))/9 or y = 10/9 - (7 i sqrt(2))/9

Step-by-step explanation:

Simplify the following:

-(13 y^2 - 6 y + 20) + 4 y^2 + 12 y + 5 y - 3 y - 4 + 2

Grouping like terms, -(13 y^2 - 6 y + 20) + 4 y^2 + 12 y + 5 y - 3 y - 4 + 2 = -(13 y^2 - 6 y + 20) + 4 y^2 + (-3 y + 5 y + 12 y) + (2 - 4):

-(13 y^2 - 6 y + 20) + 4 y^2 + (-3 y + 5 y + 12 y) + (2 - 4)

-3 y + 5 y + 12 y = 14 y:

-(13 y^2 - 6 y + 20) + 4 y^2 + 14 y + (2 - 4)

2 - 4 = -2:

-(13 y^2 - 6 y + 20) + 4 y^2 + 14 y + -2

-(13 y^2 - 6 y + 20) = -13 y^2 + 6 y - 20:

-13 y^2 + 6 y - 20 + 4 y^2 + 14 y - 2

Grouping like terms, 4 y^2 - 13 y^2 + 14 y + 6 y - 20 - 2 = (-13 y^2 + 4 y^2) + (6 y + 14 y) + (-20 - 2):

(-13 y^2 + 4 y^2) + (6 y + 14 y) + (-20 - 2)

4 y^2 - 13 y^2 = -9 y^2:

-9 y^2 + (6 y + 14 y) + (-20 - 2)

6 y + 14 y = 20 y:

-9 y^2 + 20 y + (-20 - 2)

-20 - 2 = -22:

-9 y^2 + 20 y + -22

Factor -1 out of -9 y^2 + 20 y - 22:

Answer: -(9 y^2 - 20 y + 22)

______________________________________________

Solve for y:

-9 y^2 + 20 y - 22 = 0

Divide both sides by -9:

y^2 - (20 y)/9 + 22/9 = 0

Subtract 22/9 from both sides:

y^2 - (20 y)/9 = -22/9

Add 100/81 to both sides:

y^2 - (20 y)/9 + 100/81 = -98/81

Write the left hand side as a square:

(y - 10/9)^2 = -98/81

Take the square root of both sides:

y - 10/9 = (7 i sqrt(2))/9 or y - 10/9 = -(7 i sqrt(2))/9

Add 10/9 to both sides:

y = 10/9 + (7 i sqrt(2))/9 or y - 10/9 = -(7 i sqrt(2))/9

Add 10/9 to both sides:

Answer: y = 10/9 + (7 i sqrt(2))/9 or y = 10/9 - (7 i sqrt(2))/9
