Answer:
The standard form of the equation for this line can be:
l: 2x + 5y = -15.
Step-by-step explanation:
Start by finding the slope of this line.
For a line that goes through the two points 
and 
,
.
For this line,
.
Find the slope-point form of this line's equation using
, and- The point
(using the point 
should also work.)
The slope-point form of the equation of a line
- with slope
and - point
should be 
.
For this line,
The equation in slope-point form will be
.
The standard form of the equation of a line in a cartesian plane is
where
, 
, and 
are integers. 
.
Multiply both sides of the slope-point form equation of this line by 
:
.
Add 
to both sides of the equation:
.
Therefore, the equation of this line in standard form is .
Answer:
<h2>
60 cm^2</h2>
Solution,
Let ,
a = 13
b = 13
c= 10
then,
s = a + b + c /2
= 13 + 13 + 10 / 2
= 36/2
= 18
Now,
Area of triangle:
Hope this helps ....
Good luck on your assignment...
Answer:
a = -1
b = -9
c = 9
d = 3
e = 3
f = 2
g = 3/2
Step-by-step explanation:
* Lets explain how to solve the problem
∵ 
are rational fractions
- To add or subtract the rational fractions they must have same
denominator
∵ 6 - 2x must be written 2x - 6, take (-1) as a common factor from 6 - 2x
∴ - 1(-6 + 2x) = - 1(2x - 6)
∴ 
∴ a = -1
∵ 9 ÷ -1 = -9
∴ = 
∴ b = -9
∵ The denominators of the two fractions are 2x - 6
∴ We can add them by adding their numerator
∵ 3x + -9 = 3x - 9
∴ = 
∴ c = 9
∵ 3x - 9 has a common factor 3
∴ 3x - 9 = 3(x - 3)
∵ 2x - 6 has common factor 2
∴ 2x - 6 = 2(x - 3)
∴ = 
∴ d = 3 , e = 3 , f = 2
- The fraction has same factor (x - 3) up and down then we can cancel
them together
∴ = 
∴ g = 3/2
Solve for x:
-59 = 7 x
-59 = 7 x is equivalent to 7 x = -59:
7 x = -59
Divide both sides of 7 x = -59 by 7:
(7 x)/7 = (-59)/7
7/7 = 1:
Answer: x = (-59)/7
