It takes Dimitri 9 minutes to make a simple bracelet and 20 minutes to make a deluxe bracelet. He has been making bracelets for

longer than 120 minutes. If x represents the number of simple bracelets that he has made and y represents the number of deluxe bracelets he has made, the inequality 9x + 20y > 120 represents the scenario. Which is a possible combination of bracelets that Dimitri may have made?

Answer: 7 simple bracelets and 3 deluxe bracelets

Step-by-step explanation: Let x represents the number of simple bracelets that he has made and y represents the number of deluxe bracelets he has made.

Dimitri takes 9 minutes to make a simple bracelet = 9x

Dimitri takes 20 minutes to make a deluxe bracelet = 20y

We are told that Dimitri has been making bracelets for longer than 120 minutes.

So, 9x + 20y > 120 is the equation.

9 (7) + 20(3) > 120

= 123>120

Information we know :

9 minutes = 1 simple bracelet

20 minutes = 1 deluxe

Possible combinations :

If x was . . . 1 and if y was . . . 1

[ 9 x 1 ] + [ 20 x 1 ] < 120

If x was . . . 4 and if y was . . . 2

[ 9 x 4 ] + [ 20 x 2 ] < 120

If x was . . . 2 and if y was . . . 5

[ 9 x 2 ] + [ 20 x 5 ] < 120

Consider two functions: g(x)=−x2−6x and the quadratic function ​f(x)​ shown in the table.
S_A_V [24]

Answer:

Hence average rate of change is greater for f(x) in (0,3).

Yes. f(x) is greater than g(x) in the interval (0,3)

Yes. g(3) <f(3)


Step-by-step explanation:

To find average rate of change of f and g in (0,3)

f(3)-f(0)/3 = (9-0)/3 =3

g(3) = -9-18 = -27

g(0) = 0

Rate of change in(0,3) of g(x) = -27/3 =-9

Hence average rate of change is greater for f(x) in (0,3)

---

Both f and g have intercepts of y as 0

Hence both are equal.

3) Yes. f(x) is greater than g(x) in the interval (0,3)

Because g(x) <0 for all x in (0,3) while f(x) >0

4) g(3)= -9-18=-27 <f(3)

Given AB=10cm, CD=11cm, and AD=39cm, find the length of BC
liraira [26]

<u>Answer:</u>

BC = 18 cm

<u>Step-by-step explanation:</u>

As we can see from the diagram:

AB + BC + CD = AD

⇒ 10 cm + BC + 11 cm = 39 cm

⇒ BC + 21 cm = 39 cm

⇒ BC = 39 cm - 21 cm

⇒ BC = 18 cm

RUDIKE [14]

Answer: 315 miles

Step-by-step explanation:

let onward speed = x mph, then distance = 7x

return speed = (x+18) mph, (same) distance = 5(x+18)

equating the two,

7x = 5(x+18)

2x = 90 ==> x = 45 mph

so distance = 7*45 = 315 miles
