Answer:
D 1.33
Step-by-step explanation:
B and C are less than 1
A is one and .30
D is one and .33
33>30
Yes it is. We know this cause 1 is smaller than 5 and 6 is bigger than 2.

Answer:
y = -1x -4
Step-by-step explanation:
The point slope equation is y - y1 = m(x -x1).
You will have to plug in the points (-3, -1) and (2, -6).
y - (-1) = m (x - (-3))
To find "m", find y over x.
m = (y2 - y1) / ( x2 - x1)
m = (-6 + 1)/(2 + 3)
m = -5/5
m = -1
Then plug in "m"
y + 1 = -1(x + 3)
then distribute the "m" into the parenthesis and isolate y or subtract 1 from both sides.
y + 1 = -1x - 3
y = -1x -4
Answer:(A²-B²) = (A-B)² + 2AB
Step-by-step explanation:
Hi there!
When we have an equation standard form...

...the formula of the discriminant is
D = b^2 - 4ac
When
D > 0 we have two real solutions
D = 0 we have one real solutions
D < 0 we don't have real solutions
1.) Find the value of the discriminant and the the number of real solutions of
x^2-8x+7=0
Plug in the values from the equation into the formula of the discriminant

D > 0 and therefore we have two real solutions.
2.) Find the value of the discriminant and the number of real solutions of
2x^2+4x+2=0
Again, plug in the values from the equation into the formula of the discriminant.

D = 0 and therefore we have one real solution.
~ Hope this helps you.
