Answer:
(4,8)
x=4
y=8
Step-by-step explanation:
x is the first number
y is the second number
x+y=12
x-y= -4
Let's add y and 4 to the second equation to get y by itself
x+4=y
We can substitute this value in for y in the first equation
x+x+4=12
2x=8
x=4
We can then use x=4 and plug that into any equation
4+y=12
y=8
The answer is (4,8)

<u>Equation of the line</u>
A line can be expressed in many forms.
The equation of the line in slope-intercept form is:
y=mx+b
Being m the slope and b the y-intercept.
The point-slope form of the equation of a line is:
y-k=m(x-h)
Where m is the slope and (h,k) is a point through which the line passes.
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:
We are required to find a line with slope m=4 passing through the origin (0,0).
Using the point-slope form:
y-0=4(x-0)
Simplifying
Answer:
13
Step-by-step explanation:
5 has been added by the 21 to make 27 to leave with adding 5 to old y and leaving the new variable y 13
Actually Welcome to the concept of Equilateral triangles.
Since, from the name itself, equilateral triangles have all sides and angles equal.
Hence the correct answer is
==> D. All sides are the same length.
