Given:
The two points are (-1,10) and (2,4).
To find:
The equation of line which passes though the given points.
Solution:
If a line passes through two points, then the equation of line is
The line passes through (-1,10) and (2,4). So, the equation of line is
Using distributive property, we get
Adding 10 both sides, we get
Therefore, the required equation of line is .
<span>The long piece should measure 7.5 feet or 7'6" (7 foot 6 inches).
If x is the length of the short piece then the length of the long piece must be 3x. The total length of the uncut beam is 10 foot.
This can be represented by :
x + 3x = 10
4x = 10
x = 2.5
As x = 2.5 = length of short piece, then the long piece measures 3x = 3(2.5) = 7.5 feet.
There are 12 inches in a foot so 7.5 feet = 7'6"</span>
Answer:
<h2>C ≈ 12.56 m, A ≈ 12.56 m²</h2>
Step-by-step explanation:
The formula of a perimeter (circumference) of a circle:
<em>d</em> - diameter
The formula of an area of a circle:
<em>r</em> - radius
We have <em>d = 2r = 4m → r = 2m.</em>
<em>Substitute:</em>
<em>Use π ≈ 3.14</em>
Answer:
10
Step-by-step explanation:
6x = 60
Answer:
75
Step-by-step explanation:
We line up the tens place of 33 and 42 as well as the ones place so that it looks like:
33
+42
--------
Then we add first the ones, which is 3 + 2 for 5. Then we add the tens together, 3 + 4 is 7. We put the five first since its in the ones place and the 7 second since its in the tens place for 75.
