15=7x+1-5x
Put like terms together. ( group anything alike)
15+1=16
7x-5x=2x
16 2x
—- ——-
2x 2x
2x/2x cancels itself out.
16 divided by 2 is 8
x=8
I hope this helped!
Find the perpendicular line then find the intersection then find the point
perpendicular lines have slopes that are perpendicular
the slopes multiply bo -1
y=mx+b
m=slope
y=2x-3
2 is slope
2 times what=-1
what=-1/2
the equation is
y-3=-1/2(x-8) or
y=(-1/2)x+7
find intersection
at (4,5)
distance bwetweeen (8,3) and (4,5)

D=2√5
distance= 2√5

Step-by-step explanation:
Answer:
x= 
Step-by-step explanation:
Given: 
This is a quadratic equation.

Taking common 3 from the equation given
⇒ 
dividing both side by 3
⇒
By using different factor, we can observe this trinomial can not be factored.
∴ solving it by completing the square.
⇒ 
adding 9 on both side
⇒ 
To get a perfect square number as coeffecient of x is 4, lets add both side by 4.
⇒
we know, 
∴ 
Taking Square root on both side, remember; √a²= a
⇒ 
opening parenthesis
⇒ 
subtracting both side by 2
∴ x=
