Answer:
0.
Step-by-step explanation:
n^2 - 2n.
The first term is when n = 1 so it is 1^2 - 2*1
= -1.
The second term is 2^2 - 2*2
= 0.
Third is y=-2x-2, second is y+4=-1(x-3), first is y+5=-1(x+4)
Answer:
y=7x
Step-by-step explanation:
that's the most simplified you can get this equation.
Answer:
43
Step-by-step explanation:
65+72=137
180-137=43
Answer: Last option.
Step-by-step explanation:
For this exercise you need to find the Discriminant.
The formula used to find the Discriminant, is the following:
In this case, given the Quadratic equation:
You can identify that:
Knowing those values, you must substitute them into the formula and then you must evaluate in order to find the Discriminant.
You get that this is:
By definition, if:
Then the Quadraitc equation has 2 nonreal solutions.
