Answer:.
Step-by-step explanation:
.
Whenever a quadratic equation is in the form
(i.e. the leading terms is 1), you can solve it by looking for two numbers that give when summed and when multiplied.
So, in your case,
So, we're looking for two numbers such that:
you can clearly check that these numbers are 3 and 4.
Depending on if you're solving for X or Y:
X less than or equal to 4y/3 -5
Y greater than or equal to 3x/4+15/4
Answer:
(2a,2b)
(-4a,b)
Step-by-step explanation:
for the first one
the x value of coordinate L is going to be twice the value of the x coordinate of k (a)
That being said the x value of L = 2a
The y value of L is going to be half the value of the y value of coordinate A ( 4b )
4b/2=2b so the y value of coordinate L is 2b
now we put the values as an ordered pair
The answer would be (2a,2b)
