Answer:
<em>(-3, -129)</em>
<em></em>
Step-by-step explanation:
Given
Two lines:
are perpendicular to each other and intersect at point (-8,3).
To find: (P, Q)
Solution:
The two lines intersect at (-8,3).
It means, the equation of line will be satisfied when we put value of x = -8 and y = 3
Putting in the second equation, we will get an equation in P and Q:
Given that two lines are perpendicular.
It means the product of their slopes will be equal to -1.
i.e.
Slope of a line of the form is given as:
So, slopes of given lines are:
Using the condition:
Putting the value of P in equation (1):
So, answer is <em>(-3, -129)</em>
Answer:
A. 9x^4 and 3x^5y
Step-by-step explanation:
there are two ways to solve this:
first way:
You can solve this my substituting numbers for x and y in this case i used 2 for x and 3 for y and see which one is equal to the original equations
the second way is the regular way
when you add or subtract numbers with variables and exponents you want to add the constants and add the exponents in this case is the same as
=
and you can do the same process for subtraction
=
