Answer:

y = \frac{3}{4} x

Step-by-step explanation:

The equation of a line passing through the origin (0, 0 ) is

y = mx ( where m is the slope )

m = \frac{rise}{run} = \frac{3}{4}, thus

y = \frac{3}{4} x

<u>Answer: </u>

The equation of the line passing through (0,0) and (4,3) is  y=\frac{3}{4} x

<u>Solution: </u>

Given pair of points are (0,0) and (4,3)

Here, x_{1}=0 ; y_{1}=0 ; x_{2}=4 ; y_{2}=3

We know the slope of an equation is given by y = mx+c

Where “m” is the slope of the line and “c” is the y-intercept

To find the value of m, we use the below given formula

\mathrm{m}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Substituting the values we get,

\mathrm{m}=\frac{3-0}{4-0}=\frac{3}{4}

Putting the value of m in the slope intercept form we get,

y=\frac{3}{4}x + c

To find the value of c, we substitute the value of x and y from any two given point. Lets take x = 4 and y = 3

\begin{array}{l}{3=\frac{3}{4}(4)+c} \\ {3=3+c} \\ {c=0}\end{array}

Therefore the slope intercept equation becomes y=\frac{3}{4} x

Interpreting composite functions in the real world The volume of air in a balloon is represented by the function v(r)=4/3 ³, whe
adoni [48]

There are two <em>true</em> statements:

  1. When the function is composed with r, the <em>composite</em> function is V(t) = (1/48) · π · t⁶.
  2. V(r(6)) shows that the volume is 972π cubic inches after 6 seconds.

<h3>How to use composition between two function</h3>

Let be <em>f</em> and <em>g</em> two functions, there is a composition of <em>f</em> with respect to <em>g</em> when the domain of <em>f</em> is equal to the range of <em>g</em>. In this question, the <em>domain</em> variable of the function V(r) is replaced by substitution.

If we know that V(r) = (4/3) · π · r³ and r(t) = (1/4) · t², then the composite function is:

V(t) = (4/3) · π · [(1/4) · t²]³

V(t) = (4/3) · π · (1/64) · t⁶

V(t) = (1/48) · π · t⁶

There are two <em>true</em> statements:

  1. When the function is composed with r, the <em>composite</em> function is V(t) = (1/48) · π · t⁶.
  2. V(r(6)) shows that the volume is 972π cubic inches after 6 seconds.

Twelve pounds less than twice janes weight is 270 pounds. What is Janes weight?
Tpy6a [65]
Janes weight = x
Twelve pounds less than twice janes weight is 270 pounds
12 less than 2x is 270 

2x -12 = 270   (add 12 to each side)
2x = 270 + 12
2x = 282   (divide 2 from each side)
x = 282/2
x = 141

The answer is 141 pounds
