Answer:
x^2+6x+3=0
(X+3)^2-9+3=0
since (x+3)^2>=0 for any real value of x
at vertex
(X+3)^2=0
X=-3
i.e y=0-9+3=-6
vertex (-3,-6)
at y intercept x=0
y=3
x^2 coefficient is positive
therefore this is a concave up graph
Answer:
75000(2)^n
Step-by-step explanation:
from the first book she earned 75000 and when she writes another she gets double the amount so X2 then to the power of n cause it represents the number of sequels.

Triangles cannot have two 90 degrees because that would add up to 180 and triangles need 3 angles to add to 180
You can't have an obtuse angle and a right angle. say the obtuse angle was 110, and a right angle is 90. 110 + 90 is more than 180.
Two obtuse angles would be more than 180.
This leaves us with B being correct, because you can have an obtuse angle and an acute angle, and it can be less than 180 degrees.

Answer:
$14.97
Step-by-step explanation:
she downloads three movies at $4.99 per movie
4.99 * 3 = 14.97
Start by solving for x in the first problem:
3x=3+9y
x=1+3y
Then plug that into the second equation:
6(1+3y)-3y=-24
6+18y-3y=-24
15y=-30
y=-2
Then plug that back into first equation:
3x-9(-2)=3
3x+18=3
3x=-15
x=-5
Then I would check your answer by plugging those into both equations:
3(-5)-9(-2)=3
-15+18=3
3=3 CHECK
6(-5)-3(-2)=-24
-30+6=-24
-24=-24 CHECK
So the answer is x=-5 y=-2
