Answer:

Let's solve for x.

−2(x+3y)=18

Step 1: Add 6y to both sides.

−2x−6y+6y=18+6y

−2x=6y+18

Step 2: Divide both sides by -2.

−2x/−2

6y+18

−2

x=−3y−9

in 2014 the attendance at jefferson schools fall festival was 650 in 2015 the attendance was 575 what was the percent change

Gnoma [55]

There was 11.54% decrease in attendance.

Step-by-step explanation:

Attendance in 2014 = Old value = 650

Attendance in 2015 = New value = 575

Change = New value - Old value

Change = 575 - 650 = -75

The negative sign indicates a decrease in attendance.

Decrease percentage = $\frac{Change}{Old\ value}*100$

$Decrease\ percent=\frac{75}{650}*100\\\\Decrease\ percent=\frac{7500}{650}\\\\Decrease\ percent=11.538\%$

Rounding off to nearest hundredth

Decrease percent = 11.54%

There was 11.54% decrease in attendance.

What is the recursive rule for this geometric sequence? 1/2, -2, 8, -32

Gnesinka [82]

Answer:

see explanation

Step-by-step explanation:

A recursive rule allows us to find the term in a sequence from the previous term.

From the given geometric sequence find r the common ratio

r = $\frac{-2}{\frac{1}{2} }$ = $\frac{8}{-2}$ = - 4

Hence recursive rule is

$a_{n+1}$ = - 4 $a_{n}$ ( a₁ = $\frac{1}{2}$ )

A phone plan costs $29.99 per month and includes 200 minutes of calling time. Minutes over 200 are charged at a rate of 25 cents

mylen [45]

Step-by-step explanation:

357-200 is 157 extra minutes (we are only counting the extra minutes)

157*0.25 is 39.25 (this is how much is the extra minutes in total cost)

therefore, add 39.25 and 29.99

29.99+39.25 is 62.24

Therefore, the total bill was $62.24

hope this helps :)

Have a nice day !
