I mean I think so I’m not completely sure it’s a really hard question
Answer: 13
Step-by-step explanation:
Equilateral triangle means that all sides are equal
Soo
3x + 1 must be equal to 5x - 9
3x + 1 = 5x - 9
-2x = -10
x = 5
Substitute x as 5 into either side value
3(5) + 1 = 15 + 1 = 16
So, all sides equal 16
Which means that y + 3 also equals 16
y + 3 = 16
y = 13
Y(2)-y(1)/x(2)-x(1)
9-7/-2–(-2)
0
It is a vertical line
Answer:
The given function
was replaced with
then the value of k is -3
that is k=-3.
Step-by-step explanation:
The given function is
and when x=x+k then 
Now to find the value of k:
Put x=x+k in the function f(x)
Now comparing equations (2) and (3) we get







Therefore k=-3
Therefore the given function
was replaced with
then the value of k is -3
that is k=-3.
