(X,Y) = (4,0)


That’s what I got.

Answer:

(4,0)

Step-by-step explanation:

4(-x + 5y) = 4(-)

4x + 3y = 16

-4x + 20y = -16

4x + 3y = 16

23y = 0

23y/23 = 0/23

= 0

y = 0

then for x

we substitute the value gotten from y into the equation.

san4es73 [151]
If you divide 96 by 12 you get 8. This means he texts 8 words per minute. If you then multiply 8 by 14 you get 112 which means he can text 112 words in 14 minutes.

) Luci Lulu opened a cookie store in the mall. She found that the relationship between the price of a cookie, p, and the number
lozanna [386]

Answer:

The maximum revenue Luci can make selling cookies in one day is $4,004,000.

Step-by-step explanation:

Given;

x = −2000 p + 4000 ..................... (1)

Revenue = xp

Revenue = (−2000 p + 4000)p =

Revenue = −2000p^2 + 4000p .................... (2)

The price at which Luci will the maximum profit can be calculated by finding the derivative of equation (2), equating to 0, and then solve for p as follows:

−4000p + 4000 = 0

4000 = 4000p

p = 4000 / 4000

p = 1

This implies that the price at which Luci will the maximum profit is $1.

Substituting p = 1 into equation (2) to obtain the maximum revenue Luci can make selling cookies in one day, we have:

Revenue = (−2000 * 1)^2 + (4000 * 1)

Revenue =  −2000^2 + 4000

Revenue = 4,000,000 + 4000

Revenue = 4,004,000

Therefore, the maximum revenue Luci can make selling cookies in one day is $4,004,000.

Help please I would greatly appreciate it
Reptile [31]

Hi!

Heidi won 1/5 = 0,2

Mike won 0,4

Brenda won 25% = 0,25

Luis won 1 - 0,2 - 0,4 - 0,25 = 1 - 0,85 = 0,15 = 15% => 0,15 * 120 = 18

Luis won 18 tokens.

Hope this helps!
