The slopes will be opposite reciprocals.
This means that they will be the opposite sign and the reciprocal.
For example, if the slopes of 2 eqautions are 3 and -1/3, they are perpendicular.
Answer:
x=-2
Step-by-step explanation:
-2x-4=8+4x
-6x=8+4
-6x=12
divide both side by -6
x=-2
Answer:
is the solution to the system of equations.
Step-by-step explanation:
Given the system of equations as:

and

To find:
The solution to the system of equations = ?
Solution:
Here, we are given two equations and two variables i.e.
and
.
So, we can solve the system of equations for the values of
and
.
Let us first consider the 2nd equation.
we already have the value of
.
Now, let us put the value of
in the 1st equation to find the value of
.


So, the solution to the system of equations is:

Answer:
D = (55)(4.5)
425 = 60 T
200 = R (2.5)
4.6 hours
59 mph
217 miles
Step-by-step explanation:
Answer:
1).
2).
Step-by-step explanation:
Here the given equation is 
We have to factor the perfect square trinomial on the left side of the equation
So left side of the equation is 
= 
since [(a+b)²= a²+b²+2ab]
Therefore the factorial form of the equation will be

Now we have to solve the equation by applying square root property
