bearing in mind that an x-intercept is when the graph touches the x-axis and when that happens y = 0, and a y-intercept is when the graph touches the y-axis and when that happens x = 0.
Answer:
1st to 4th: Sam, Cras, Randy, Charte
Step-by-step explanation:
The places are determined by putting the times in increasing order.
<u>time</u>, <u>place</u>, <u>name</u>
25.85, 1st place, Sam
25.90, 2nd place, Cras
32.20, 3rd place, Randy
32.28, 4th place, Charte

<em>Additional comment</em>
Sometimes it is easier to compare values when they all have the same number of decimal places.
Answer:
-17
Step-by-step explanation:
ok well I can't really see Sam and John's answer but -3-14 is equal to -17
if you see that there's a negative in front of the first number and its also subtracting you have to make that subtract sign an addition sign then change the second number to a negative like this:
-3+-14 then you just add.
With Sam and John whichever one had -17 as their answer is correct
Answer:
The Slope is
The Equation is
Step-by-step explanation:
Two Point Form
Given:
Let,
point A( x₁ , y₁) ≡ ( 0 ,-1)
point B( x₂ , y₂ )≡ (-4 , 4)
To Find:
Equation of Line AB =?
Solution:
Substituting the point A( x₁ , y₁) ≡ ( 0 ,-1) and B( x₂ , y₂ )≡ (-4 , 4) we get
Equation of a line passing through a points A( x₁ , y₁) and point B( x₂ , y₂ ) is given by the formula Two -Point Form,
Now on substituting the slope and point A( x₁ , y₁) ≡ ( 0 ,-1) and B( x₂ , y₂ )≡ (-4 , 4) we get
OR
Equation of a line passing through a points A( x₁ , y₁) and having slope m is given by the formula,
i.e equation in point - slope form
Substituting the values we get
To solve this, make the equation:
2l+2(l-4)=72
4l=80
The length is 20 meters.
Then, plug 20 in the other equation:
w=l-4
The width is 16 meters.
