The year in which the two quantities will be equal is 2133.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Here we have the following data.

y=0.221x-368.264 For men

y=0.168x-255.196 for women

So when we will equate these two equation we will get the year in which two quantities will be same.

0.221x-368.264=0.168x-255.196

0.221x-0.168x=368.264-255.196

0.053x = 1123.068

x= 2133 year

Hence the year in which the two quantities will be equal is 2133.

Anastaziya [24]

Answer:

\frac{1}{4} lbs/person

Step-by-step explanation:

Here is the complete question: Find the rate of change for the situation:

A chef cooks 9 lbs of chicken for 36 people and 17 lbs of chicken for 68 people.

Given: 1st situation, A chef cook 9 lbs chicken for 36 people.

           2nd situation, chef cook 17 lbs chicken for 68 people.

∴ 1st situation, weight of chicken per person= \frac{9\ lbs}{36\ person} = \frac{9}{36}

  Weight of chicken per person= \frac{1}{4} lbs/ person

2nd situation, weight of chicken per person= \frac{17\ lbs}{68\ person} = \frac{17}{68}

Weight of chicken per person= \frac{1}{4} lbs/ person

In both the situation chef cook same amount of chicken per person, which is \frac{1}{4} lbs/ person

∴ Rate of change is \frac{1}{4} lbs/ person

x^2=6x+1 rewrite the equation by completing the square your equation should look like (x+a)^2=b or (x-c)^2=d
ryzh [129]

Answer:

(x - 3)² = 10

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

  • Completing the Square

Step-by-step explanation:

<u>Step 1: Define</u>

x² = 6x + 1

<u>Step 2: Rewrite</u>

  1. Subtract 6x on both sides:                    x² - 6x = 1
  2. Complete the Square:                           x² - 6x + 9 = 1 + 9
  3. Factor:                                                    (x - 3)² = 10

The area of a rectangle that has a length of 10 and a width of w.
alexdok [17]

Answer:

B

Step-by-step explanation:

To find the area, multiply length by width (lw, or l×w). If the length is 10, that just leaves the width, which is unknown. We can substitute 10 for l, which leaves us with 10w.

F(x)=2x+3/4x+5<br>find f(-9)<br>​
mylen [45]

\implies {\blue {\boxed {\boxed {\purple {\sf { f(-9)= 0.48}}}}}}

\large\mathfrak{{\pmb{\underline{\orange{Step-by-step\:explanation}}{\orange{:}}}}}

f(x) =  \frac{2x + 3}{4x + 5} \\

For f(-9), put "-9" for every value of "x".

↬f( - 9) =  \frac{2( - 9) + 3}{4( - 9) + 5}\\

↬ f(-9) =  \frac{ - 18 + 3}{ - 36 + 5} \\

↬ f(-9) =  \frac{ - 15}{ - 31}\\

↬ f(-9)=  \frac{15}{31}\\

↬f(-9)=  0.48\\
