Sierra is selling bracelets to raise money for the Language Club at school. Each bracelet with yellow beads sells for $5. Each b

racelet with orange beads sells for $6. She raised $660 for the club. The number of bracelets with yellow beads that Sierra sold is 8 more than twice the number of bracelets with orange beads. Let y represent the number of bracelets with yellow beads and r represent the number of bracelets with orange beads.Which system of equations will solve for the number of each type of bracelet sold? 5 y + 6 r = 660. y = 2 r + 8. 6 y + 5 r = 660. y = 2 r + 8. 5 y + 6 r = 660. y = r + 8. 6 y + 5 r = 660. r = 2 y + 8.

Answer:

Correct answer is:

5y+6r=660\\y=2r+8

Step-by-step explanation:

Given that Number of bracelets with yellow beads is represented by y

Each bracelet with yellow beads is sold for $5.

Total money raised by bracelets with yellow beads = Number of bracelets sold \times Money raised by sale of one such bracelet = 5y

Also Given that Number of bracelets with Orange beads is represented by r

Each bracelet with orange beads is sold for $6.

Total money raised by bracelets with orange beads = Number of bracelets sold \times Money raised by sale of one such bracelet = 6r

Given that total money raised by sale of both type of bracelets is $660.

so, the first equation becomes:

5y+6r=660 ....... (1)

It is also given that "<em>The number of bracelets with yellow beads that Sierra sold is 8 more than twice the number of bracelets with orange beads</em>"

\Rightarrow r =2r+8 ...... (2)

So, by equation (1) and (2), the system of equations is:

5y+6r=660\\y=2r+8

-2x^2 + 4x + 16 in vertex form​
Reil [10]

Answer:

y = - 2(x - 1)² + 18

Step-by-step explanation:

- 2x² + 4x + 16 ← factor out - 2 from the first 2 terms

= - 2(x² - 2x) + 16

using the method of completing the square

add/subtract ( half the coefficient of the x- term)² to x² - 2x

= - 2(x² + 2(- 1)x + 1 - 1) + 16

= - 2(x - 1)² + 2 + 16

= - 2(x - 1)² + 18 ← in vertex form

WILL MARK BRAINLEST PLS HELP
Rudiy27

Answer:

None

Step-by-step explanation:

The center of the ellipse is at  (2,  4)

The length of the x axis is  a=  (8-2) =6

The length of the y axis is b=(16-4) = 12

The formula for an ellipse is

(x-h) ^2       (y-k)^2

----------- + -------------- = 1^2

a^2              b^2

where (h,k) is the center

and a and b are the  lengths of the major and minor axes

(x-2) ^2       (y-4)^2

----------- + -------------- = 1

6^2              12^2

 none of your choices have b>a  and for the ellipse to be vertical b>a
