When planning for a party, one caterer recommends the amount of meat be at least 2 pounds less than 1/3 the total number of gues
ehidna [41]

Answer:

The graph in the attached figure

Step-by-step explanation:

Let

x-----> the total number of guests

y -----> the amount of meat

we know that

The inequality that represent this situation is equal to

y\geq \frac{1}{3}x-2

Note The inequality is "greater than or equal" because the given statement say "at least"

The solution of this inequality is the shaded area above the solid line y=\frac{1}{3}x-2

The slope of the solid line is positive

The y-intercept of the solid line is -2  

The x-intercept of the solid line is 6

therefore

The graph in the attached figure

Remember that

The values of x an y cannot be a negative number

sammy [17]
<span>The Jonestown will be much colder compare to the Cooperville.
See how the solution goes:
At 1:00, the both share the same temperature
Let X = the temperature of both town

Jonestown
=> 1:00 = x
=> 2:00 = x – 10
=> 3:00 = x – 10 – 8
At 3:00, Jonestown dropped a total of 18 degrees

Cooperville
=> 1:00 = x
=> 2:00 = x – 6
=> 3:00 = x – 6 – 2
At 3:00, Cooperville dropped 8 degrees only.</span>

Determine the length and midpoint of the segment whose endpoints are (–15, 9) and (–4, 11).

(-15,9) \\&#10;x_1=-15 \\&#10;y_1=9 \\ \\&#10;(-4,11) \\&#10;x_2=-4 \\&#10;y_2=11 \\ \\&#10;\hbox{the length:} \\&#10;l=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=\sqrt{(-4+15)^2+(11-9)^2}=\\&#10;=\sqrt{11^2+2^2}=\sqrt{121+4}=\sqrt{125}=\sqrt{25 \times 5}=5\sqrt{5} \\ \\&#10;\hbox{the midpoint:} (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}) \\&#10;\frac{x_1+x_2}{2}=\frac{-15-4}{2}=\frac{-19}{2}=-9.5 \\&#10;\frac{y_1+y_2}{2}=\frac{9+11}{2}=\frac{20}{2}=10 \\&#10;(-9.5,10)

The length of the segment is 5√5, the midpoint of the segment is (-9.5,10).
